Ireland. 30 years.

It didn't sound like you were in the states. Is your system gravity fed or do you have a booster oump? Over here we install air chambers, (shock absorbers, see image) on all bathroom sinks and the kitchen sink. These are hidden in the wall so you won't be able to see them. Can you call a plumbing shop and ask if you install them in your country? Regards, tom

Hello Tom.
Thank you for your reply. I know the air chamber you are talking about,
We do not use them in this country.

Then your best bet is to make and install one of your own. Cut a tee into the supply from the storage tank and install a 3/4" pipe with a permanent cap about 14" long. This should absorb any shock caused by water hammer. Good luck, tom

Michael this is just a thought but could it be possible that the pressure tank in the attic could be becoming "Waterlogged" if you are not familiar with this it is when the tank loses its air space and has too much water in it. Normally the air in the tank acts as a cushion when you turn off the water, because water does not compress it will ram the end of the pips and make a hammering noise.
Not knowing what you have as a system it is hard to tell you how to remedy the problem if indeed this is the problem. But in short you have to introduce more air into the tank, normally a tank only fills about half full with water... the rest is air.

There is no cover on the tank,so air pressure is not the problem.
Thank you.

1.You closed your tap to quickly.
2.The pipes are not well fixed into its saddles.
3.Your tank is made of metal and is fix on Iron sheet roofing.
