Water Pressure Reducing Valve Installation

Turn off all the water.

Water pressure reducing valve installation.

It is best to check this before you have soldered up your pipes. Hoses are a common location. Using threaded pipe and fittings attach a pressure gauge to each side of the pressure reducing valve. Use a tubing cutter to remove a section of water pipe as indicated by the marks made in step 4.

Apply the coupling and put in the adapter. Installed directly after the water meter in homes commercial buildings and manufacturing plants a water pressure reducing valve automatically reduces the pressure from the water supply main to a lower more sensible pressure. If you install your valve the wrong way around the flux will not serve to block the water and the pressure will not be reduced. There are two types of water pressure reducing valves direct acting and pilot operated which use globe or angle style bodies.

Hold the valve assembly against a water pipe and mark where to cut the pipe. If the pressure is excessively high install a pressure reducing valve. Shut off the water to the house then drain water from the plumbing system. Mount the fitting upon the water pressure reducing valve and then fit this into position.

So any new home will have one of these valves installed. Warm up all of these fittings with the soldering torch and then apply some suitable caulking paste to the edges of the fittings. The city code for new home construction states the psi cannot be higher than 80. The flux needs to be forced down by the pressure of the water so the valve blocks the flow.

Take the water pressure reducing valve and attach it to the fittings. For the home inspector this is an issue of liability. Take the time necessary to install the extra piping on the high pressure side of your water service line to allow you to keep high pressure at certain fixtures. So the home inspector will always recommend getting the valve installed in any home new or old with a psi of 80 or higher.
