    Dear Experts !

    Situation: I am re-doing my kitchen, but the previous house owner had a butcher fit the boiler and pipes.
    these pipes are currently running outside the wall , in a haphazard way.

    Question: should the pipes be running in a channel in the wall or outside ?

    Once I know this, I may have a job for you experts :)

    Thanks
    Mickey D.

    Thanks Rob :)
    That is what I had in mind. Was not sure if I should channel out the wall under the boiler and lag and plaster in the 5 water pipes, boxing in the gas pipe. This would however create a lot of work (channeling out the wall) for little gain (smaller box).

    Would you lag the water pipes and then box them ?

    you really need to get behind the sink drainer so yup loose them in the wall - use a pipe bender it does not have to be pretty. dont use plastic its too close to boiler imho. wrap the pipes in tape before you sink in the in wall behind drainer you have a gas pipe there u MUST get a gas fella in let him do the lot - wont take long and will be cost effective

    Gas pipe Looks undersized.
    As above. Drop straight down and run behind the units. As long as there is no built in appliance, will be an easy job.
    Please get a gas safe guy to do it, as i suspect that gas pipe is insufficient.

    To be honest if your going to go through the effort I would get a new boiler whilst your at it. Otherwise when your due a new boiler, as chalked said that gas pipe will probably need upgrading.

    I agree with you and as well with chalked.

    I’d also upgrade the boiler with a new one and add a filter to spähen system too. Looks just shocking the install

    Thanks gents for the advice
    I agree the plumber who did this botch should probably not have been a Plumber.
    I will do the following :
    Get hold of a plumber/ gas fellow
    Ask him to upgrade the gas pipe and move the water pipes

    should be an easy and inexpensive job.

    Thanks again so much for all your input ☀️☀️

    If you asked for quality works with good materials then nothing is cheap and inexpensive. I would rather spend more money for good quality materials and get a good engineer.

    Hi I am new on here, this thread is similar and i couldn't work out how to upload mine....yesterday the plumber cut out our old copper pipes and replaced them with plastic ones. He is telling me that the pipe/connection where they join at the top can be plastered straight over. is this correct, i'm not entirely convinced he knows what he is talking about. I have been on line all night trying to find the answer but there is so many conflicting statements. a) can you plaster over the connection bits, he said he just has to tape them up b)is there anything you need to put over the pipe to stop heat transfer/plaster cracking in some places it is very close to the top of the plaster board either side of it c)should he have included an inhibitor for the pipes in the installation d)these are barrier pipes, how will they be traced in a wall? any help appreciated thank you Lindsay

    Plastic pipe will soften and move when heated and as a rule of thumb burying joints is avoided, that's not to say it will definitely leak but doing so increases the risk. It may cost more but I'd have it soldered and re-piped with copper. Why was it removed in the first place?

    The pipes were on the outside of the wall, there was a few leaks on the copper ones so we opted for plastic so they could recess them so we can have them skimmed. The joints stick out somewhat and plaster board will not go over them. i can see there is not enough depth so they are saying they can be plastered straight over, joint and pipes. I'm not convinced

    Get a straight edge and bridge it across the highest points (pipe clips), if it's a couple of mm that isn't enough should be at least 5mm preferably more. They could've recessed the block work to give more space, plastic or copper.

    Never bury compression fittings

    What I would do and it works fine is get some of that white plastic wire cover strip chase that into wall over the top of the pipes - leaving them to heat up and move about. Then when all is good get some bonding plaster or car body filler and trowel it over to a smooth finish
    flush with the wall, fine wall filler, paint - job done. less theory and more practice Rob Foster aka Centralheatking
