Hello,
My first post -- good site!
I have had problems with a vibrating sound in my house's plumbing, which I eventually realized was due to thermal expansion (I have a Watts PRV). The noise is relieved by opening the hot water tap for a second or two.
I bought a 5-gal expansion tank from Sears as I have 2 40-gal water heaters. In reading the instructions, they say that I need to make sure that I have a bypass- type PRV, which seems to me to negate the need for the expansion tank. Also, I'm supposed to permanently install a water pressure gauge and make sure PRV is set for a house pressure of 40 PSI.
Is this all liability prevention on the part of Sears, or do I need to do all of this? I have no idea what my current pressure is, but 40 PSI seems low to me, esp. with a sprinkler system. (Of course, I could reroute the sprinkler system to tap in before the PRV, but I am trying to do this job as simply as possible...)
Thanks!
