water hammer Allan?...if so then the culprit is often the bog tank...fit a torbeck valve or you can get a little plastic hose that dips into the water...preventing the hammer...but if you fit one of these...dont forget to put a non-return valve in the feed pipe to the bog....
Thanks mate but you missed the beginning of the thread.............no banging going on in my kitchen lol
