Fix Water Leaks Before They Cause Major Damage

Monday, April 30th, 2012

Water leaks are one of the most destructive and frustrating problems in many Lansdale homes. Undetected water leaks can rot wood, destroy drywall, and cause mold to grow in unseen spaces of your home. Spending the time and money to find and fix water leaks before they cause significant damage is one of the most cost-effective actions a homeowner can take.

Sinks

Cabinets beneath kitchen and bathroom sinks are a good place to start. Look for signs of water damage or build up. Mold and mildew are telltale signs of water leaks. Touch the pipes, particularly the areas where they enter the faucet. Run the hot and cold water faucets for a few minutes and repeat the inspection. Finally, fill the sink with water, let it stand a few minutes and open the drain. Now check the drain pipe and the joints that connect it to the sink for leaks.

Dishwashers

Dishwashers can’t easily be checked for leaks without pulling them out from beneath the counter. But you can inspect the water lines that connect the dishwasher to the kitchen sink. For some units, you may be able to shine a flashlight beneath the dishwasher to look for puddles.

Toilets

Toilets can leak from the water supply pipes filling the tank and from the seal between the toilet and the waste pipe in the floor. Flush the toilet several times and carefully look for any signs of leaks in the  joints of the water supply pipe and the floor around the base of the toilet. Lift the lid off the tank and flush the toilet. When the tank refills, the water should completely shut off. If the flush valve or water control unit is old, corroded, or loose, the water will continue to run. Running water cools the water delivery pipe to the toilet and the tank, which will cause them to collect condensation in humid weather. The condensation will drip and eventually cause water damage to the floor behind the toilet. Bottom line – don’t ignore a running toilet. Have the water control and flush valve fixed or replaced.

 Tubs and Showers

Inspect the caulking around the tub or shower. Old, cracked, or missing caulking can allow water to leak into the wall. Water dripping from a leaky faucet or shower head will go down the drain and not cause any damage, but the faucet may also be leaking water behind the tub or shower.

Hot Water Heaters

Finally, inspect the hot water heater for leaks, and the boiler if the house has hot water heating. The first place to look is the floor around the appliance, but also look at the joints where the water pipes connect.

Problems Caused by Poor Water Quality in Open Loop Systems

Monday, April 23rd, 2012

As geothermal heating and cooling systems go, an open loop configuration can be an excellent choice, provided the environment supports it. Open loop systems work very effectively and efficiently because the deep water is held at an almost constant temperature year round. This property makes it a very good source of heat for the geothermal system.

However, an important factor to consider before choosing an open loop system is the quality of the water coming from the source. Although you won’t drink the water, the quality still matters a great deal, as poor water quality can cause serious problems in your geothermal system.

Let’s take a look at some common water quality problems and the damage they can potentially do to an open loop geothermal system in King of Prussia.

 Mineral Deposits

If the water is filled with minerals — frequently called “hard water” — those minerals can be deposited within the geothermal coils. As they build up on the walls over time, they can slow the flow of the water or even clog it completely.

Hard water does not necessarily preclude the use of an open loop system. It just may call for extra maintenance, such as periodically flushing the system with a mild acid solution to remove mineral build-up.

 Impurities

Impurities in water, especially metals like iron, can also cause clogs. Most frequently this occurs in the return well of the geothermal system. Again, these impurities do not necessarily mean an open loop system can’t work for you, but you should consult with the contractor prior to installation for solutions to this problem.

 Particulate and Organic Matter

If you plan to use surface water such as a pond or spring as the source for your open loop system, make sure to test the water composition thoroughly. An excess of sediment or organic matter can clog up your geothermal system very quickly.

Ideally, these are all situations that your King of Prussia geothermal contractor will anticipate and discuss with you ahead of time, so that your open loop system can be installed in such a way as to preempt any problems with water quality.

Heat Pump Tip: Outdoor Maintenance

Monday, April 16th, 2012

Sometimes, the trickiest part about owning your Doylestown heat pump is keeping the outdoor components maintained. Because they are outside and generally out of sight, it can be easy to forget or neglect them. But because they are outside and exposed to the elements, outdoor heat pump components need attention and maintenance to keep them running properly.

The two most important routine maintenance functions you can do as an owner of an outdoor heat pump are keeping it free of debris and keeping it level.

Every month or so, inspect and clean your outdoor heat pump to make sure it is free of leaves, dirt and other debris. These can easily be sucked in by the fan and reduce the efficiency of the whole system. Turn the power off to the unit and use a vacuum or broom to remove any accumulated debris.

Once or twice a year, use a carpenter’s level to make sure the whole thing is sitting level on the pad. Use the level to gauge both side to side and front to back. While you are doing this, check the insulation for erosion or gaps. If you see that it is not level or the insulation is wearing thin, have a contractor come out reset the unit on the concrete pad or patch up the insulation.

These are two small maintenance tasks that you don’t have to do very often, but they can make a big difference in the performance and life of your heat pump.

In addition, you should always have your whole Doylestown heating, ventilation and cooling system inspected by a professional annually in order to keep everything maintained and in good repair.

Common Questions about Heat Pumps

Monday, April 9th, 2012

Even if you installed a heat pump in your Lansdale home years ago, you may still have questions about the normal operation of your indoor and outdoor units. Here are answers to a few of the more common questions we get about Lansdale heat pumps.

Do I need to schedule a heat pump maintenance visit before each season, or just once a year?

Scheduling a yearly maintenance visit is necessary to the proper upkeep and safe operation of your Lansdale heat pump. This also extends the life of the system and helps it run more efficiently. However, scheduling a visit before the heating and cooling seasons isn’t necessary, unless you’ve had any concerns or issues with your heat pump.

Should I be concerned about the steam coming from my outdoor unit?

All heat pumps have a defrost cycle that melts the frost off of the outdoor coils in the winter. The steam rising from the outdoor unit results from the defrost cycle. If you notice that the defrost cycle lasts longer than ten to fifteen minutes, or if it cycles on and off frequently, you should call an HVAC service technician to look at your heat pump. There could be an issue with airflow that is affecting the compressor.

I just installed a heat pump. Why is my furnace running?

Many heat pump systems use the furnace fan blower to help distribute the heat throughout the house. Unless you’ve installed a geothermal heat pump, your furnace is most likely your backup heater, so it will kick on when the outside temperature drops below 20° F.

Is it really that important to clean my outdoor unit? It’s impossible to keep it clean all the time.

Yes, cleaning the outdoor unit is an especially important maintenance task. Not only does a routine cleaning of all the outdoor components maintain your heat pump’s efficiency and performance levels, it also prevents safety hazards. When you schedule a yearly maintenance visit with one of our technicians, cleaning the coils and outdoor unit is part of the service; however, if you want to clean the coils yourself, have one of our technicians show you how to do this before you attempt it on your own. You could suffer from electric shock if you are not familiar with the proper cleaning procedure. You can also help by making sure that the debris is cleared from around the outdoor unit.

If you have any questions about the heat pump in your Lansdale home, or if you’d like to schedule a maintenance appointment, give Carney Plumbing, Heating & Cooling a call any time.

What Exactly Are High Efficiency Boilers?

Monday, April 2nd, 2012

You have already read plenty about how energy costs are rising. You know plenty well that heating your New Hope home is a substantial expense, and that the cost of running a boiler is constantly on the rise.

But as technology has gotten better, so have boilers become more efficient at providing heat. It stands to reason that a more efficient boiler is one that costs less to run…but what does “efficient” really mean in the context of boilers? What makes a boiler “high efficiency”?

 What Is a High Efficiency Boiler?

All boilers are rated according to a standardized system of rating efficiency, called the Annual Fuel Utilization Efficiency (AFUE). Essentially, this rating tells you how much heat energy is produced by your New Hope boiler compared to how much energy it draws. The higher a boiler’s AFUE rating, the more efficient it is.

For a boiler to be called high efficiency, it must carry an AFUE of at least 90%. For basis of comparison, older systems carry an AFUE of about 70%, while mid-efficiency systems run at about 82%.

In addition, a high efficiency system has a second heat exchanger for capturing and condensing flue gases, as well as a closed combustion system.

These three things — an AFUE of 90% or above, condensing flue gases and closed combustion – define a high efficiency boiler.

The initial investment in a high efficiency boiler can be costly, but the savings over time in your New Hope heating bills make it well worth the expense.

If you would like a high efficiency boiler installed in your home, give Carney Plumbing, Heating & Cooling a call today!
