Evening all So, My Little boy was in the shower this evening and all of a sudden red hot water started to flow out of the little plastic overflow pipe which is next to the main shower out let. He was not scolded but it gave him a bit of a shock I can tell you (he is only 3 1/2 afterall ) Does anyone know what might be causing this problem? There is no blockage in the shower outlet pipe and both warm water and hot water come out of both the pipes at the same time It is a Triton AMber 2 electric shower with a mains cold water feed. Any help or advice would be appreciated. Thanks. David.
