3/4" Press Pressure Reducing Valve w/ Gauge (Low Lead, Pre-adjustable)

Water companies comply with minimum pressure requirements but don't concern themselves with high pressure, but if you have water filters, washing machines, dishwashers or a refrigerator with cold water or an ice maker, they all are subject to damage if the pressure is over about 120 psi, or even spikes above that level. This is the solution for that at less cost than a service call to replace a refrigerator water valve and much less than it costs to deal with water damage from a leaking filter or appliance. Water companies could, but don't do a better job of regulating high pressure because it would cost them to install pressure regulators. My water company told me that they pump the water out at 175 psi to reach high points in the system and provide fire protection, so I'm left with doing it for myself. You should too if you have high pressure or spikes.

I bought a Caleffi 535951HA pressure reduction valve - it failed within 6 months. SupplyHouse replaced if after I sent in the failed unit. The second unit failed within 3 months. This is simply a poor product, which is why it is so inexpensive. Clearly you get what you pay for. As you can see in the picture the PSI in the gauge is higher than the setting. Often the PSI is closer to 110, which is the city supply pressure we are trying to reduce.
