In response to Re: normal pressure for homes

Normal pressure for a home is 35-65 depending on whom you talk to.
Most PRV's come set for 50 PSI.
When you have a PRV on the line, you should also have an expansion tank.
The water heater will heat up and expand the water, increasing the pressure.
The expansion tank gives a place for the added volume to go.
Rebuild kits may be hard to find, and sometimes it is easier to replace the entire unit.

: I have measured the water pressure at two locations in my home and they confirm that my water pressure is just short of 100 psi. What is the typical psi range for a residential home? You see my hot electric hot water heater's pressure relief valve is dripping at different intervals. It currently reads 100psi at the bottom hose bib. A pressure reducing valve was installed five years ago and I suspect that it is not working. I would like to know if the valve is rebuildable. (Conraco ASSE B356 size 1/2 25psi-75psi
: 400 PSI MAX input 180degree limit) My basement is finished and the exisiting valve is almost imposible to replace, but it has a removeable dome and I am wondering if a rebuid kit is available?
