All taps in house lukewarm since work done in bathroom

[Deleted member 96713]

Hi all!

Recently had some work done in the bathroom (retiled floor, new sink and toilet put in).

Since then ALL the hot taps (shower, bath, bathroom sink, kitchen sink) in the house are producing water that could at best be described as warm.

We have a combi boiler new in 2015 but it was fine before this so I'm assuming the boiler's not at fault. Also, the heating is fine.

Is likely to be a master mixer somewhere that would control the heat of all the taps? I'm a complete dunce when it comes to plumbing I'm afraid.

The house itself is a Victorian terraced house in East London if that helps.

Thanks!

is it a mixer tapthat was fitted
check if boiler is ok to do this check how hot the hot water the pipe leaving the boiler is.
if that is ok then it could be a mixer tap or shower passing cold into the system causing the water to cool, either way get plumber back

If you can, isolate your hot water supply, and then turn on a hot tap. Water should stop coming out after 5-10 seconds. If cold water continues to come out, then as said above, you have a mixer which is incorrectly passing water from cold to hot. Usually a stuck NRV.
