Hi, can anyone help me with this? I recently had a new shower pump fitted. Today it suddenly stopped working; it wouldn't come on when I wanted to have a shower. I have worked out that it comes on when turned on to cold water only, but when moved to hot water it stops. I have opened the hot water inlet to make sure that the filter isn't clogged. It isn't. Is there an air-lock? If so, how do I get rid of it? Please help! Thanks
