    Toilet water hammer
    Hi hope you can help... I have recently had a new torbeck valve fitted in my toilet and ever since this the toilet bangs when the valve shuts of on the toilet.. I have had a water hammer arrester fitted, also the valve has been checked on the stop cock.. that is OK... so I had the pressure reducing comb (for high pressure) taken out of my torbeck now I get a bang when it flushes and one when it shuts off, also all my pipes have been checked and are all secure... I noticed when I had my old torbeck removed it had two washers behind the blue retaning nut,. also why can you buy two types of torbecks one with a metal pin which holds the black shut off washer in place the other one has a black shut off washer with a small plastic pin in it which locates in a hole in the flush stork... would it help by putting the low pressure comb in instead of the one for high pressure, because the toilet without one in sounds like a jet wash when filling up,. please I need help before I put a sledge hammer through my toilet.:(

    What is your water pressure, should be about 40-45 psi.

    How high, exactly, is your water pressure? Another solution would be to add a air chamber, (see image) just ahead of the angle stop. Good luck, Tom

    Please tell us you psi. Even if it doesn't cure your immediate issue a pressure reducing valve can be easily, inexpensively installed to provide protection from many other possible plumbing problems. A buddy of mine had a pvc toilet supply line bust at his weekend retreat. By the time he got to the cabin 350,000 gallons of water had flowed through the house for a week causing over $300,000 damage. Insurance paid for evrything except his $3000 water bill.
