    Who else has seen this?

    I would like to hear the reason as to why you think they are in the valves always closest to the PVB..

    my thoughts: Bad Boiler drains > high air pressure and constant water pressure over the years> screw falls out right into my flow pro's/ irritrol Jartops,1 inch.

    what do you think?

    Also, What is you first thought when you see an old controller
    (lets say a toro vision or a weathermatic) with the 1 and a half amp fuses?

    And said controller keeps popping fuses...What is your next step...

    I know mine, and I also know how i found the problem...What would you all do in a situation like that? con first or field first?

    dunno on the screws, seems like a Northern US issue deal.

    As for the amperage problem, I would meter each solenoid for mA draw.

    If I saw a 1.5 Amp fuse in a Toro controller, I'd be wondering if a smaller value hadn't been incorrectly replaced.

    Those fuses only blow when big problems occur.

    The loose screws can go back to day one of the install. Never hurts to see if your cheapo import boiler drains are properly assembled.

    If it's a Febco PVB, a lot of time the screw will come out of the bottom of the check valve, and then move and get stuck down stream. Also the little fork/prong (name is passing me right now) that the screw holds in place will get lodged as well. Both can then damage the diaphragms
  7. Ditto on the TORO... If a 1.5 amp fuse blows I'd think solenoid short. By the way the SmartLine can de changed to a 1.5 amp fuse for older solenoids.

    Yet one more reason to love Febco PVBs

    FOr some reason they only appear in irritrol valves.
