I have a 50mm PVC ringmain which has two places where i have branched off the ringmain. One to the front of the house which feeds two bathrooms and 1 geyser. I have a water hammer in the ceiling.
The other branch off the ringmain is at the back of the house and it feeds 1 bathroom and 1 geyser. A bathroom consists of a shower, toilet and basin.
off the ringmain there is 1 garden stand pipe in front and one at the back.
The water tanks are on the ground that feed the house. There is a pressure pump (3 bar) where the water tanks are that feeds the ringmain.
I have a water hammer at the front bathroom in the ceiling and at the back. I have put a pressure relieve valve just before the water enters the geysers as per the diagram that came with the geysers. The pipe that comes from the water supply into the house has been built in the wall and goes up to the ceiling and then back to the wall surface where the pipe then enters the geyser. I have used a T piece to make the water go in two ways. One down into the geyser and the other down to the bathrooms.
the water hammers are in the sections where the supply for the geyser and the bathroom come out the wall.
No matter where a fawcet is opened in the house or the garden, the water hammer happens before reaching the geysers.
This happens without water being drawn from the geyser.
The pressure does not hold its pressure continuously, its pressure goes up to 3 bars and when a tap is opened it drops its pressure and this restarts the pressure pump up again. Do i put pressure release valve just after the pressure pump or must i put a larger pressure pump unit in?

The terms you use in your post are unfamiliar to those of us in the U.S. Can you explain to us what a Geyser is? Also what is a Ringmain? Then someone might help you.

I assume a "ringmain" is a main line that circles the building on the outside, but 'geyser", possibly a water heater/storage tank, is not a common term.
