    Just installed a Pressure reducing valve.. now have spiking psi from 60 to 150psi!
    Hi Folks,

    Will an expansion tank be able to absorb a 90psi pressure difference? I have 2 50 gal WH's and the static pressure is 60psi, but spikes to 150psi when both are firing. The pressure subsides about 10psi per 15 minutes, or if when the I relieve it using a cold faucet in about 4 seconds.

    T and P is still leaking when the pressure is high, so would a Exp tank help, or do I need like 2?
