Use a tubing cutter to remove a section of water pipe as indicated by the marks made in step 4.
Water pressure reducing valve installation.
Shut off the water to the house then drain water from the plumbing system.
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.
Using threaded pipe and fittings attach a pressure gauge to each side of the pressure reducing valve.
Warm up all of these fittings with the soldering torch and then apply some suitable caulking paste to the edges of the fittings.
If the pressure is excessively high install a pressure reducing valve.
Remove the pressure gauges and rubber o rings from the valve assembly.
It is best to check this before you have soldered up your pipes.
Take the water pressure reducing valve and attach it to the fittings.
Apply the coupling and put in the adapter.

The city code for new home construction states the psi cannot be higher than 80.
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 any new home will have one of these valves installed.
There are two types of water pressure reducing valves direct acting and pilot operated which use globe or angle style bodies.
Unions at the valve.
Mount the fitting upon the water pressure reducing valve and then fit this into position.
Hold the valve assembly against a water pipe and mark where to cut the pipe.
Turn off all the water.
Hoses are a common location.
