Just moved into a new house which has a mixer shower however we only get cold water. We can get Luke warm water if we flush the toilet at the same time.
A friend has told me the shower water feed is the wrong way round. I have included a pic.
Any help would be appreciated
It sounds as though you have the cold feed to the shower from the mains and the hot feed from a tank. When you flush the toilet you reduce the mains pressure which is then closer to the hot (tank) feed pressure. Both hot and cold feed should originate from a tank to be at the same pressure. Guessing a bit but I hope it helps.
