AristonWater Heater Expansion Vessel Kit A

Q: Is this expansion vessel is pre-charged on delivery and what is the pre-charged pressure?

The pressure vessel is pre-charged at 3.5 bar.

Q: Will this stop continual dripping from pressure relief valve on my 10ltr unvented water heater

Yes. It is necessary to allow for expansion. Hot water expands by up to 10% and the vessel allows for this. If you don’t fit then the pressure forces it’s way out via the tap (dripping) or out of the pressure relief valve.

Q: what fitting do i need to connect this to my 15mm pipe work?

I suggest you take the vessel to a plumbers merchant and ask them to give you an adapter from the thread on the vessel to 15mm pipe.

Q: Is the membrane made from epdm rubber?

It is synthetic rubber but I cant say if it is EPDM, Nitrile , or something else. I cannot think of any water component that would cause a problem with those.
