Once the regulator is installed you will want to perform a yearly pressure test to ensure the water pressure regulator hasn’t failed. The higher the incoming pressure from the city side – the higher chance you will have of the water pressure regulator wearing out and becoming ineffective.
Testing the pressure regulator is fairly easy and only takes a simple water pressure gauge (found at any local hardware store) and about 2 minutes. All you have to do is attach the gauge to a hose bibb and turn the water on. You will instantly see the pressure reading to complete the yearly test.
Low Water Pressure – Low water pressure is somewhat a rarity when your water source is supplied via the public water system. In most cases, low water pressure issues tend to be associated with an old water system that lacks volume (pressure is static no matter if its a 1/4in pipe or 10in pipe delivering it), or some sort of restriction caused by a failed water softener or other added device.
Low Water Pressure is more common on high rise buildings and well water systems: as a booster pump of sorts is generally required in order to increase the delivery side pressure. If you have a booster pump the system will generally trigger an alarm indicating some sort of failure and need for corrective action.
Absent a booster pump system application the most common cause of low volume (often confused with low water pressure) is restricted volume caused by an old galvanize water system. The best remedy for an old galvanize water system with restricted volume is a complete water system repipe.
