Gettysburg Plumber’s Guide: Environmental Benefits of Trenchless Repair

Wednesday, March 7th, 2012

Pipe replacement is a messy business. For decades, the only real way to do it was to rumble in with a big machine (or men with plenty of shovels) and dig up your Gettysburg property to access the leaking, cracked pipe. However, with modern technology, trenchless pipe repair and replacement is now possible and while the biggest benefits are to your wallet and your lawn, you might also be interested to know how environmentally friendly the process is.

Less Resources Needed

Have you ever seen someone digging up a pipeline? The equipment needed is impressive. Backhoes, trucks and multiple workers to get the old pipe out of the ground and a new one in. And once the process is completed, the concrete and lawn destroyed by the digging need to be replaced. It’s a very invasive procedure.

With trenchless technology, most of those resources are not needed. This means less fuel used to power large machines, less destruction of your property and no impact on the roadway or sidewalks that would require paving once completed.

Existing Pipe Pathways

Have you ever considered the impact a pipe line being laid has on the ecosystem beneath your property? Digging up all that space and displacing plants, animals and insects alike can have a tremendously negative impact on the micro-ecology on your property.

Trenchless replacement allows a plumber to use the existing pipe pathway beneath your property, which avoids displacing anything with fresh digging. It also doesn’t impact the plants or trees growing on your property. You gain a new pipe line without any damage to the carefully manicured landscaping you’ve done on your property.

Minimal Subsoil Impact

Even when laying new pipes, trenchless technology only affects the space underground where the pipe will be laid. This tears up far less of the subsoil which has a less extensive environmental impact on the water shed around your home.

There really is no reason to use a traditional exhume and pull pipe replacement method when trenchless technology makes it possible to just as easily replace the pipes for the same or less money and minimal environmental impact. Depending on your circumstances and the scope of the work that needs to be done, your pipe repair or replacement may be significantly better served with trenchless technologies.

If you have any questions about trenchless or no-dig technologies, give Larry & Sons Plumbing, Heating & Air Conditioning a call today!

Hanover Plumbing Guide: What to Look for When You Have Water Damage

Friday, February 24th, 2012

Water can be a beautiful thing. But it can be a very nasty thing, too. While water is an essential for life, it brings a high price tag when gone unchecked and allowed to seep, leak, and drain into your Hanover home. Damage caused by water can cause structural damage to a building and destruction of its contents. When left unchecked – over time – water damage can lead to mold growth and have a serious affect on building occupants’ health.

The destructive forces of water leave telltale signs throughout a building. Let’s look at some.

  • Wood damage – water can saturate wood, causing it to rot and decay. Check for discolored wood around plumbing fixtures, a sure sign of an ongoing or older leak that has since been repaired. Just because a leak has been fixed, the after-effects can linger. Soft or uneven surfaces around a plumbing fixture are a sure indication of water damage. Pull back carpeting, pads, tiling, or flooring to get to the root of the problem.
  • Drywall damage – porous material like drywall can leave many signs of water damage and, like wood, can be seriously degraded by water damage. Check for discoloration around plumbing fixtures and soft spots. Don’t assume that a dry surface that is stained is not a structural problem. You may have to cut out the drywall to reach the true source of the water damage.
  • Ceiling tile stains – a sure sign that water is coming in from a source above a roof or ceiling. Ceiling tiles are a porous material that are great for showing every little bit of moisture or water that comes in contact with them. The same is true with plaster or drywall ceilings. Stains indicate a more serious problem and should be investigated right away.
  • Damp, musty smells – water can leave some unpleasant odors, especially untreated water. Leaks or standing water are a source for higher humidity levels in a home. If you are standing in an area where water has soaked into floors or walls, there is often a damp, humid smell. Don’t mistake it for high humidity levels in the home. The smell can come from hidden sources like a leaking pipe joint or broken valve behind an access door.
  • Mold build-up – wood and drywall surfaces provide great food for mold growth when saturated with water. The mold can be of a harmless nature but often can become dangerous black mold. When black mold spores are airborne they can cause respiratory problems and even worse, medial problems down the road. Look for unusual clusters of mold in damp areas and if you find some, immediately call a professional plumber to suggest clean-up and to repair the source of the water leak.

There are many signs of water leakage in the home, caused by leaking or broken pipes, dripping faucets from worn-out washers, cracks in the walls and foundations allowing ground and rain water to seep in, etc. Call a Larry & Sons if you have any signs water damage in your Hanover home.

Mercersburg HVAC Repair Question: What Is Refrigerant Pressure and Why Does it Matter?

Friday, January 20th, 2012

Refrigerant is often called the “lifeblood” of mechanical heating and cooling devices like the heat pump and air conditioner in your Mercersburg home.  The main function of refrigerant is to transfer heat through a closed loop system. Various heating and cooling (HVAC) components require different operating pressures to move refrigerant and process the “refrigeration cycle.”

In a nutshell, the refrigeration cycle involves refrigerant, which changes from a liquid to a vapor and back to a liquid again by the addition of pressure and heat. In a refrigeration system, pressurized refrigerant passed through an expansion valve into an evaporator and pressure is reduced. The evaporator is a tube which passes by the area to be cooled. When the pressure drops, this liquid refrigerant changes into a vapor, which absorbs vaporized heat from the area around the evaporator. After the heat is absorbed by the refrigerant, it flows to a condenser, where it passes over coils, absorbs heat from the hot vapor, and condenses back into a liquid. The liquid is returned to the compressor and the cycle begins again.

Today’s refrigerants – especially those used in residential applications – are broken down into two different types, labeled R-22 and R-410A. R-22 is made up of a chlorofluorocarbon (CFC) chemical, which has been found to be damaging to the Earth’s ozone layer. It has been replaced by R-410A, which is made up of a hydrofluorocarbon (HFC) chemical and will eventually be phased out by the year 2020. One of the biggest differences between the two are their operating temperatures. HFCs operate at much higher refrigerant pressure.

This change between refrigerants has created some interesting dynamics and challenges for the HVAC trade. Gauges used to check pressure readings have all changed. And mechanical compressors do not operate with a variety of refrigerants, so the compressors and coils need to be swapped out, too. To give you an example, let’s say you are shopping for a new central air conditioner. Chances are, the new air conditioner will run on R-410A. Your old air conditioner ran on R-22. In order to “match” the compressor in the your new air conditioning unit to the existing indoor coil, you will need to replace the coil and the lines running from your outdoor condensing unit to your indoor air handling unit, which is mounted to your furnace.

You don’t have to understand the refrigeration cycle to know that today’s high-pressure HFC refrigerants require different test instrumentation and retrofitted or upgraded mechanical equipment. The change in operating pressure is a small price to pay for a safer environment.

Why It’s Important to Think about Plumbing in Waynesboro

Wednesday, January 4th, 2012

If you’re like most people in Waynesboro, your plumbing is usually the last thing on your mind. Until something goes wrong, that is. And it’s pretty much guaranteed that you’ll have a clogged drain or leaky pipe in your home sooner or later. But while some plumbing problems are certainly unavoidable, there are quite a few things you can do to help keep them to a minimum and avoid larger plumbing emergencies later on.

Professional Checkups

For one thing, it’s a good idea to have your plumbing system checked by a professional every year or two. They can make sure that no roots interfere with the pipes in your yard and that things are generally flowing smoothly throughout the system. A professional inspection will also uncover any leaks, cracks or partial blockages that you may not have realized were there but that could cause significant damage later on if not dealt with promptly.

Do It Yourself Maintenance

In addition to professional inspections, though, there are some things you can do on your own. For instance, every season brings new challenges for your home plumbing. Many people know that there are dangers associated with freezing pipes in the winter, but did you know that there are things you can do all year round to help your plumbing work better?

Fall is the best time of year to start disconnecting outdoor faucets and checking them for leaks. If you take these steps before the really cold weather sets in, you’ll be able to get necessary repairs done well before freezing outdoor temperatures become a problem.

This is also a good time of year to check for proper insulation around pipes and to make sure your water heater is tuned up and ready to go for the winter. Sure, you use it all year round, but the colder it is outside, the harder your water heater has to work all winter.

Once spring rolls around again, there are plenty of other tasks you can take on to ensure the continued healthy functioning of your plumbing. For instance, you should check all of your outdoor drains and gutters to see that they’re clear of debris that could have built up during the winter. You can also flush out your water heater again to clear whatever’s accumulated over the winter and check any pipes and faucets for problems that may have developed during the cold months.

Greencastle Plumbing Guide: How to Test for Water Leaks

Monday, December 26th, 2011

A water leak can be a big problem. Not only does it increase your bill – pouring water out of pipes that you now have to pay for – but it puts your Greencastle home and its foundation at risk. Steady water flowing into concrete under your home is incredibly dangerous if left unchecked. Here are some quick tips to check for a leak if you suspect there might be a problem.

Your First Clue

The first clue that there might be a leak in your home is the water meter. If it suddenly starts to rise much faster than normal, you probably have a leak. You use the same amount of water on most days for showers, dishes and laundry. If the meter goes up by double each day, that water must be going somewhere. Many meters will even have a marker on them that indicates a leak (a red flag that you are using too much water and it’s probably a leak).

Finding the Leak

If you notice your water meter rising when all of your water using appliances are off (or the little warning meter is going off), you have a leak – let’s find it.

Start by turning off the main shut off valve to your home. Make sure your shut off valve is working properly by running a faucet after the valve is closed to see if water still comes out. If the leak indicator or meter is still moving after the shutoff valve is closed, the leak is before the shutoff valve, but after the meter. If it’s not moving, the leak is somewhere in your home, after the shutoff valve.

From here, look for signs of water damage or dampness throughout your home (and possibly outside). Most of the time, an indoor leak will manifest somewhere – either in a dripping ceiling or a damp spot on the carpet.

If no such evidence presents itself, look outside for water. Damp spots on your lawn on dry days are a sure sign as well. If you cannot find any signs of water leakage on or around your property, it may be time to call in a professional plumber to take a closer look.

How Do I Check a Gas Furnace Draft Pressure Switch? A Question from Mont Alto

Wednesday, October 12th, 2011

There are many reasons why a furnace stops working and in many cases, a Mont Alto homeowner can perform some simple diagnostics to pinpoint the problem. Finding the problem is one thing – fixing it is another. When in doubt, don’t try it yourself. Call a qualified professional.

But let’s look at one possible problem and solution you may be able to perform yourself – testing the draft pressure switch. The draft pressure switch on a gas furnace allows an electrical current to pass through to ignite the furnace. The pressure switch monitors the draft conditions and won’t allow the furnace’s gas valve to open unless draft is correct.

If the switch is malfunctioning, so too will (or will not) the furnace.

The best way to locate the switch is by consulting with your owner’s manual or by going online and simply typing in the words “gas furnace draft switch.” It is identifiable by its round size and is bolted to the outside of the furnace. It should be nearby the draft inducer motor because the two are connected by a metal tube. The tube may sometimes be the culprit, too. A tube that is blocked with condensation may cause the switch to go bad.

To check for proper function, first turn off power to the furnace, either by shutting down the “on’ switch at the furnace or shutting off the circuit breaker.

Use a volt ohm meter to check if the switch is opening and closing properly. Start by zeroing out the meter’s probes by touching the tips together. Using the dial (could be analog or digital), set the meter to 24 volts. Ground the black probe by attaching it to any metal part of the furnace. Then place the end of the red probe on the metal tube connecting the draft pressure switch to the draft inducer motor.

If the switch is working properly the meter should read at least 24 volts, or very near that. If the reading is short of 24 volts, the switch is not working correctly. At that point you may decide to replace it or call a professional to do the task (recommended).

Always remember that there are many sources which will help you diagnose and repair a problem, especially those available through the Internet. If you search YouTube.com you will find many videos advising you on how to repair certain components. Use all of the resources available to you and keep the phone number of a qualified and professional heating and cooling contractor nearby.

How Much Will a High Efficiency Furnace Save Me? A Question From Chambersburg

Friday, September 30th, 2011

The furnaces you can buy these days in Chambersburg are all much more energy efficient than those available even 10 years ago. However, that doesn’t mean that all of the current models are created equal. There is still a pretty big variation when it comes to energy efficiency and when it comes to price, so you need to really know what you’re looking for if you want to get the best deal out there.

The first thing you should understand when you’re trying to pick out a furnace is how energy efficiency for this type of equipment it measured. All furnaces come with an annual fuel utilization efficiency (AFUE) rating that reflects just exactly how energy efficient they are.

Any furnace you buy today will have an AFUE of at least 80%, but it’s possible to purchase models with AFUEs of 97% or more. Of course, energy efficiency is generally a good thing, but there are some other things to consider when you’re trying to decide just how energy efficient you need your new furnace to be.

What this calculation really comes down to is how much you’ll be able to save monthly and annually with a higher efficiency furnace. While your heating bills will certainly be lower the higher the furnace’s efficiency is, you will also pay more up front for the highest efficiency models.

Keep in mind that a furnace with an 80% AFUE is still quite efficient and will almost certainly save you a considerable amount monthly when compared to the unit you’re currently using. And because 80% AFUE furnaces are so much cheaper than those with upper 90% AFUE ratings, they often wind up as the more cost effective alternative overall.

How Often Do You Change Your Filters? A Question From Mercersburg

Monday, September 19th, 2011

The core component of any good air quality system in your Mercersburg home is the filter. A good air filter removes almost all of the particles that inundate your home every day – from the pet dander that flakes off of your cats or dogs to the pollen released by plants both indoors and out.

But many homeowners are not aware of when they should change the filters in their air quality system. They know it should be done regularly, but how often and when do you ignore the manufacturer’s recommendation to ensure higher quality air?

Know Your Home

The first thing to consider is the size of your home and what types of contaminants you must deal with each day.  If you don’t have any pets and don’t keep any plants inside, your biggest air quality issue is likely dust, and dust will only fill up the filters quickly if you have a large family.

However, if you have a lot of pets, multiple plants and a large family, the odds are that your filter is being put through the ringer every day – asked to filter out a tremendous number of contaminants. This is when you might need to change the filter in your air cleaner or other HVAC equipment more often.

Changing Your Filter

If you have a high quality HEPA filter, it’ll probably work for as long as it’s rated. Only lower quality filters or those not large enough for the space in which they are installed will fail early. However, keep in mind that a HEPA filter, even when it can last longer, should always be changed no later than the manufacturer’s recommended date.

For most homes that timeframe is about 6 months. However, some higher quality filters can last as long as 12 or even 18 months in the right conditions.

How Do I Stop My Pipes from Knocking? A Question From Chambersburg

Monday, September 12th, 2011

Tell me if this sounds familiar – you are sleeping comfortably and in the middle of the night a soft but persistent knock sounds through the pipes in your Chambersburg home. At first it is easy to ignore, but inevitably the sound will grow with each passing night and eventually start keeping you awake. Luckily, there are simple solutions for knocking pipes that do not require a plumber or expensive parts.

First, it is good to know why your pipes are knocking in the first place. In most cases, knocking pipes are caused by variable water pressure in the main supply pipes coming into your home. That pressure is important because it keeps the water moving freely between pipes and into your faucets. However, when the air used in pressurizing those pipes leaks or is depleted, water moves suddenly and violently, creating the knocking sound as it traverses the length of the supply lines.

The easiest fix for this kind of knocking is to first turn off your main supply valve. Make sure you communicate to anyone in your home that you are shutting off the valve as it will stop ALL water coming in. Now, flush the lines by opening all of the faucets and flushing your toilets. Water can still leave your home through drainage pipes and this will ensure all of the supply lines are fully empty.

Once the lines are cleared, feel free to turn your main valve back on. It is important to do this slowly so that the air chambers between and around your pipes have time to refill before the water courses back into them. However, now that the pipes were fully emptied, the knocking sound should be completely gone.

It is as simple as that. In most cases, you should not need to call a plumber to help, but if you have any problems finding your main valve or shutting it off, a plumber can be helpful with the proper tools and the knowhow for various kinds of shutoff valves. Additionally, if you live in an apartment building or a shared space, you may not be able to perform this fix. Rather, you should contact your superintendent or landlord and make sure they know exactly what is happening – with any experience, they should recognize the problem and be able to make similar fixes to your pipes.

Knocking pipes can be incredibly frustrating if not dealt with as soon as they start. Now that you know how simple it is to make the fix, make a habit of regularly flushing your lines and the knocking likely will not start up again.
