too much pressure causing vibration

johnjoe 123 · 2010-08-07 13:57:25

im at a job today the house is fed off a 9" water main. and when the mains is used it starts to vibrate and is very noisey. i think the pressure reducing valve or auto fill valve might be causing it. any ideas?? asap please.

Is there a pressure reducing valve fitted on line?

You could fit an anti water hammer valve.

i didnt know until saturday that theres a difference in an auto fill valve and a pressure reducing valve. afv - euro14 prv - euro70. i replaced the afv with an exact replacment and it stopped the vibrating it was faulty or couldnt handle the high pressure. . if it happens again il replace it with a prv!! by the way whats an antihammer valve??
