Copper hot water cylinder

Posted by colin stacey, on Wed 08 Jun 2016 10:01am

Water is travelling in the wrong direction up the cold feed pipe from the bathroom airing cupboard sited cylinder to the ceiling tank, causing water to flow out of the overflow particularly once the heating system is pressurised/on. I have replaced ballcock valve and reduced water level temporarily in the ceiling tank however it refills once the water / heating cycle is on. indirect system is from approx. mid 1980's.
