    Get yourself an engineer out mate. Probably for the best.

    Tmv only on new. Replacing an existing doesn't need one. Do you have a shower or anything similar. Could be mains cold back feeding through cooling hot.

    The photo was further back in the thread. I have arranged for a plumber to visit tomorrow but just wanted the heads up on what the problem might be.

    None of us should assume but you are right. But we don’t know what was there before the bath swap but as the OP doesn’t know what they’re looking for it’s all a bit finger in the wind

    Based on that set up I would agree with Simon thinking cold backfilling

    There is a separate mixer shower above the bath taps which seems to be fine.

    Could be thermostatic though so is capable of dealing with the cold Mains

    In that case it could be the hot NRV in the mixer shower that is causing the problem.

    Goosed check valve. Changed a shower last year. All outlets in bathroom not very hot. They spent a fortune on visits to fix the combi. I was referred to change shower and swap taps. Phoned me after to tell me the water had never been so hot in the bathroom. All down to shower.

    Check under bath and see if you have on of these.

    If you don't have a TMV send a picture of bath taps and could you try get a clearer image of the cylinder and pipework later on, take a step back and include as much pipework as you can

    Does anyone else see two pumps? Maybe a thermal store with a mixer on the side...

    Do you install a tmv everytime when fitting a bath??

    You don’t have to but on the rare occasion that I have done baths in recent years I have just from a safety perspective because they tend to be elderly customers

    Thanks for all the advice and prompts. I’ve worked out there is a TMV on the cylinder pipework and think this might be the problem. I’ll let you know how I get on.

    How did you figure that out?

    Isn't it a thermal store, hence the two pumps? Rather than just a traditional cylinder.
