  • Water Pressure Reducing Valve

  • Pressure Reducing Valves

    Pressure Reducing Valves are designed to reduce incoming water or steam pressure to a safer constant predetermined downstream level. Depending on the type of valve, the downstream pressure is established by a pressure adjustment setting on the valve or by an external sensor.

    Installed directly after the water meter in homes a water pressure reducing valve automatically reduces the pressure from the water supply main to a lower, more sensible pressure.

    There are two types of water pressure reducing valves-- direct acting and pilot operated-- which use globe or angle style bodies.

    Direct acting valves are the more popular water pressure reducing valves, consisting of globe-type bodies with a spring-loaded, heat-resistant diaphragm connected to the outlet of the valve that acts upon a spring. This spring holds a pre-set tension on the valve seat installed with a pressure equalizing mechanism for precise water pressure control.

    Every Drop Counts - Why Install a Pressure Reducing Valve?


    Water Savings

    Twice as much water flows through a system at 150psi pressure than at 50psi. Much of this additional water is wasted and not needed for normal usage.


    Energy Savings

    If less water flows through the system, less energy is needed to heat domestic hot water. Calculations show that pressure reducing valves can save as much as 30% on domestic water heating costs.


    Wastewater Savings

    When the community's wastewater treatment load is reduced, cost benefits accrue to both the environment and your bottom line. Many municipalities prorate sewer usage fees based upon the water meter reading.

    Types of Pressure Reducing Valves


    Water Pressure Reducing Valves

    Water Pressure Reducing Valves are used in residential, commercial, and institutional applications to reduce incoming water pressure to a lower predetermined level, thereby protecting downstream plumbing system components and reducing water consumption.


    Steam Pressure Reducing Valves

    Steam pressure reducing valves are used in commercial, industrial, and institutional applications to regulate steam pressure. Used in applications such as oil lines, testing fixtures, autoclaves, steam tables/irons, single radiators, and vulcanizers.

    I have a well and a pump house. The well pumps into a 200 gallon equivalent pressure tank (30-50 psi),, which pumps into a 1000 gallon holding tank via a Robertson valve (pretty much a large version of what''s in your toilet tank). The holding tank is at 1 bar (14.7 psi) and allows diffused gas to be released from the well water so only water is pumped to the house.

    What gas? Don''t know, don''t care. Chlorine injection: let''s you sleep at night.

    The water from the holding tank is not pressurized (well, maybe, max 2psi) and is sent to the house via a Grundfos MQ3-45 booster pump.

    The booster pump was supposed to keep pressure between 45 and 65 psi, but no. Pressures of 85 to 90 psi seen at house: ruptured toilet feeds; fun, fun, fun ''til your daddy takes the t-bird away.

    Enter our hero: LFN45BM1-U 1" water reducing valve.

    The 1" LFN45BM1-U 1" water reducing valve has 1, 1" union valve. Which is confusing, but it also has two 1" FPT threaded connections on either end (MPT, FPT and NPT are all the same standard -- M == Male, F == Female, N == either or both).

    I chose to make the brass union coupler into a really snazzy Xmas ornament, which I don''t have a picture of, but it''s really fetching.

    Who says pumbing isn''t exciting?

    To connect the pressure reducing valve, I used two 1" Male PVC connectors, which are screwed into the valve (copious amounts of Teflon tape; really torque these down as the NPT standard is designed for this); and glued to the existing PVC between the pump and the house (e.g. torque male PVC to valve, glue slip to existing PVC).

    I also had two 1" slip x 1/2" threaded FPT tees, with brass 1/2" MPT x 1/4" FPT reducer adapters so I can have a pressure gauge before the valve and after the valve for adjustment/fun purposes. See adjustment instructions included with valve, but it''s basically: loosen lock nut, righty highty, lefty lowy.

    Sure, I could adjust the booster pump, but this is a black art and seldom practiced (existing internet sources talk about "adjusting pressure", but not "what pressure" -- low pressure, high pressure??). Besides, if, in the future I want to install some other kind of booster pump, I already have a watchdog to keep the toilets from exploding.

    One solid working water pressure valve. It was a breeze to install right out of the box and I did not need any extra parts. The one I replaced was acting up and after I completely tore it down I found out why. The spring and inner workings had corroded to a point of malfunction.

    Once installed, I then moved on to replace the water expansion tank. When the water was turned back on, I adjusted the water pressure valve to 60 psi. Everything has been working just fine now. Even though the prior water pressure was set to 60 psi, this “new” flow is much stronger and improved. “Should have done it years ago!”

    Pressure regulation works fine, however I cannot stop a leak where the inlet pipe connects to the union on the regulator. Tried teflon tape, pipe dope, pipe dope + tape and nothing will stop the very slow leak. Last resort will be to eliminate the union piece and connect inlet pipe directly. The outlet side is leak-free connected in this manner.

    This is an exact drop in replacement of the old broken Watts regulator. However, it comes with only one O-ring. I have to re-use one of the old O-ring, and it leaks a little bit. Sent email to Watts, and got the O-ring in the mail after a few days. It should have include two O-rings. Many of the usage is to just for replacement, not new installation. Two O-rings will make the life much easier, and the additional cost of one O-ring may be just few cents.
