Water Pressure Reducing Valve Installation

If you install a pressure reducing valve before the hose bib branches you will lose your wonderful high pressure.

Water pressure reducing valve installation. 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. If the pressure is excessively high install a pressure reducing valve. The city code for new home construction states the psi cannot be higher than 80. For the home inspector this is an issue of liability.

Warm up all of these fittings with the soldering torch and then apply some suitable caulking paste to the edges of the fittings. Hoses are a common location. The flux needs to be forced down by the pressure of the water so the valve blocks the flow. Apply the coupling and put in the adapter.

So the home inspector will always recommend getting the valve installed in any home new or old with a psi of 80 or higher. So any new home will have one of these valves installed. Shut off the water to the house then drain water from the plumbing system.

Remove the pressure gauges and rubber o rings from the valve assembly. Turn off all the water.
