Baffled

[leelister6]

Working in a large house, Alpha 50cd boiler feeding utility, kitchen, cloakroom and 2 bathrooms, 1 with a bath and shower and one with just a shower. Problem is, we're getting hot water from some of the hot taps and lukewarm from others, even in the same room I.e. bath tap red hot, basin lukewarm. Any ideas? Thanks Lee

Back flow from the cold usually a shower where you are getting lukewarm water turn the shower or mixer tap to cold only then run a hot in the same room but at a different point see if it comes up hot.

also could it be higher flow rate at the lukewarm outlets?

Have you got mixer taps installed?

Could be s stuffed cartridge, depending on the location along the line as to where you are getting a cross connection.

Fit check valves on mixers and showers
