    Watts Fill Valve 1156, or SB1156

    Hi gang, any feedback on these? They are basically a set it and forget type of valve. Have had a few instances over last couple of years where the rod/diaphram will not maintain set pressure, even at factory set. When troubleshooting, that assy is shot, and they aren't expensive enough to haggle with warranty so they get replaced with the same. Anyone seeing the same thing? Am I missing something?

    1156's

    Usually the only time I see trouble with the Watt's 1156 is when the backflow preventer is downstream of the fill valve or there isn't a backflow preventer at all. With the backflow not isolating the fill valve and the boiler side from the open potable side, they will rust out internally and never send make up water to the system. I see it a lot out in the field.
