Then just unscrewing the flexihose from the cylinder and capturing all the water that comes out, then screwing on the new one once it has been compression tested.

At this point the membrane is back to its initial dimensions, the pump starts again and a new cycle begins. The main purpose of the vessel is to compensate for the increase in volume of water due to the varying water temperatures in the system, e.

This seems to be a simple job of emptying the cyclinder below the line in the picture and islolating the feeds.The bracket setup for this one is well dodgy as if it breaks off the wall it will fall on the other pipes and I'll be in a whole lot of trouble!
