PRV
The main Pressure Reducing Valve (PRV) can typically be anywhere between the City Water shutoff valve by your water meter (if external) and the first "tee" in the water supply system. Though quite often it is near the main building shutoff valve inside the home.Some fixtures or appliances have their own PRV, like a hydronic heating system.
The Uniform Plumbing Code (UPC) specifies 80psi maximum. If your water service provides more than 80psi, the UPC requires a pressure reducing (PRV) valve be installed. Your 60psi is within code. Excessive pressures can exacerbate water hammer and wear fittings prematurely.
If your pressure exceeds the setting of the PRV or is below the setting
Plumbing top-out is the stage of plumbing that occurs when a home is in its frame stage. There are three stages of plumbing typically in construction. Plumbing rough (prior to the foundation being poured); plumbing topout (bringing ground plumbing up through the vents); plumbing trim (installing fixtures).
Hot water tank? On a water heater tank there is always a extra black plug in case you need to change your way of installing the pipes to it. The plug on most electric water heaters are opposite of your PRV valve (pressure relief valve) so if your PRV valve is on top then your plug will be on the side and if your PRV is on the side then your plug will be on top of the water heater if its electric.
Depending on who is asking and the type of cylinder, w/ or w/out PRV and location of the PRV, acceptable answers: Neck, Primary Manifold Access, Inlet/Outlet, Breach Point, Secondary Valve Access. Charging Access Point
