Water Pressure Reducing Valves provide safety, savings and protect valuable plumbing and appliance assets
May 1st, 2012Water pressure is often a problem in residential settings, and sometimes high pressure can cause serious problems like broken pipes, damaged water-based appliances, and even injuries to homeowners dealing with a high-pressure situation.
The basic issue is simple: municipal water systems deliver water at much higher levels of pressure necessary for the average home so there is enough water pressure in the main lines to feed the needs of the fire department at hydrants and in high-rise apartment buildings where the elevation may decrease water flow. This only makes sense.
That’s one reason most homes are equipped with a Water Pressure Reducing Valve. These valves, however, also act as pressure regulating valves that do their best to keep the water pressure within the home on an even keel. Most municipal water systems can deliver water at 200 psi, and a pressure reducing valve is often required if the system psi exceeds 80 psi. A typical home needs something less than 50 psi for normal operation. These water pressure reducing valves will also save money because the higher the pressure, the more water is running through the pipe and fixture: e.g. twice as much water will flow through at 150 psi than at 50 psi. This also reduces the amount of wastewater that is introduced to the local wastewater system, which is a benefit to the community at large.
Water pressure reducing valves are deceptively simple devices. Typically, they involve a spring and a diaphragm connected to a pintle (a pin or bolt) that regulates water flow. The spring is adjustable and is set at the desired pressure and the diaphragm acts as an equilibrium force that readjusts the spring depending on the incoming pressure.
Like everything mechanical, water pressure reducing valves can and do wear out and it is a good idea to monitor the water pressure within a home to ensure everything is ship-shape. Not all homes are equipped with them, however, and it’s probably a good idea to have that checked if there are high pressure problems. The pipes might bang and shake with too much pressure, and it can be noticed in the volume of water and its velocity (pressure) coming out of the spigot.
As stated earlier, too-high water pressure can damage pipes, causing them to burst which is never a good thing. But even moderately high pressure that doesn’t bang the pies around isn’t good for such water appliances as washing machines and dishwashers as it can more easily burst those water connector hoses and joints, as well as the tumblers, spinners and spray jets inside the machines. This could cause a breakdown, of course, but it can also simply shorten the life of the appliance.
Of course, too-low water pressure is a problem of another kind, as it disrupts lifestyle and makes water-based appliances and sprinkler systems to work at inadequate levels. A qualified, licensed plumber can measure the4 exact water pressure in a home and make the necessary recommendations to adjust that pressure to the optimal level for safety, savings and lifestyle protection – including installing or replacing a proper Water Pressure Reducing Valve when the situation calls for it.
