I'm back. Can anyone tell me the dangers to health if hot water from a cylinder mixes with drinking water. Also, we have two cylinders side by side - with one cold feed supplying both. Do they have to have separate expansions all the way up to the storage tank. Couldn't they not just be...

Yipee. success. It was a cold mains supply running through one of the showers right enough. Non-return valve fitted on hot water supply, and job done. Cheers for everyone's advice.

What a day.... I again put a non-return valve on the cold feed to the cylinder, and next thing like before the expansion started running into the storage tank. Originally I thought the coil was burst and the hot water entering the tank was coming from this. But I subsequently turned off the...
