    MasterTemp inlet=outlet :-(


    During the pool build, the plumbers plumbed the heater incorrectly. We've been feeding water from the filter through the outlet of the (unused) heater for 3 weeks. They finally came and fixed it, now the pressure reads 10# lower. Should I be concerned about the heater and the effects this might have had on the internals of the heater? It seems to heat the pool fine now, but I did begin to hear rattling from the heater 2 weeks into it.

    Hey, Ron,

    What was your psi prior to the fix? Did it really drop 10 full pounds?

    Hi Dave,

    It was at 36, now it's at 26. I hope this is a non-issue. Appears to be thus far.
