Growling 47-2

Every once in a while . It shakes the piping ,there is nothing else in the pipe that would cause it . Could it be high water pressure or just a bad seat.

  • Water pressure

    I always liked to see a PRV ahead of any feeder, electronic included. This allows control over feed rates, eliminates the singing and water hammer associated with float fillers.

    Simple boiler feeds with the factory 12# work well

    see if you can disconnect the piping on the leaving side of the feeder all the way to the pipe that enters the boiler. You tend to get a calcium build up right where the cold feed water enters the boiler and it creates a back pressure on the valve. Clean up the fittings and piping if scaled up. This some times leads to a boiler that over fills too.

    The 47 & 51

    valve & strainer assembly has a plastic hexagonal poppet that closes against flow. It's a sloppy little bugger, & can shake the c/w feed line so it can be heard over much of a large building. Been there done that.

    H. D. is right. A pressure reducing valve ahead of the feeder takes care of the problem.

    make sure the arrow is pointing towards the boiler --usually its the higher pressure on the inlet side prv will help --but i have run into a few where they were installed backwards -
