If you have an older home, your plumbing system may not have a pressure reducing valve. A pressure reducing valve reduces the pressure of the incoming water to a force that is compatible with your home's plumbing system. It protects your plumbing and water source.
What does a pressure reducing valve do?
Water from a municipality can come into a home at a pressure that is more than a residential plumbing system is capable of handling. If the water pressure is left unchecked, it can damage more sensitive residential plumbing. This damage can include valves such as faucet valves, which will leak, meaning a constant drip in the sink. It can also damage appliances, most notably the water heater, which was never intended for high-pressure water. High water pressure can significantly shorten the lifespan of a water heater.
High pressure can also cause damage that is severe enough that the water pressure can cause a leak in your home if the weak spot is in part of the system is a part that is indoors. No one wants a flood!
How does a pressure reducing valve work?
A pressure reducing valve can be installed on the water main just before any faucets or devices. This will ensure that all fixtures get water at a reduced rate. Ideally, water pressure will be no higher than 60 PSI. If the water pressure on the city side is higher, a gate in the pressure reducing valve will reduce the water pressure before it can cause damage.
How long does a pressure reducing valve last?
A pressure reducing valve can last anywhere from three to five years. A home with a faulty pressure reducing valve may have problems. When a homeowner notices the pressure reducer valve isn't working, he should have it replaced.
Signs a pressure reducing valve is bad
Low pressure water or no pressure are some of the signs a pressure reducer is flawed. Other symptoms are water hammer, thumping, or chattering in the pipes. Extra high pressure is another sign the pressure reducer has failed. A leak outdoors near the pressure reducer may also indicate that the valve itself is leaking. It could be something as benign as noticing that you have a lot more plumbing repairs than average.
A pressure reducing valve isn't tricky to install, but a professional plumber should install it unless the homeowner has some plumbing and soldering skills. A pressure reducing valve will reduce your water pressure to a rate that will be safer for your plumbing.
