## Questions & Answers

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