    I am currently extending my bathroom and have had a plumber in to remove the old radiator and fit all the new piping. The problem i have is that since everything was reconnected my combi boiler (camray 5) is isnt playing ball, when i switch the heating on the hot water comes on aswell although it is in the off position, i have to move the switch on the electric flow valve to get the water flowing through the system but it doesnt reach the two rads upstairs and the most alarming thing is the system pressure is set to 1.5 bar but will climb to over 3 bar which it never used to do and i have to switch it off, im hoping someone can help b4 i call in an engineer.

    It seems that you are now realising the difference between a plumber and a heating engineer!

    Unfortunately for the plumber, it seems that he has been doing work beyond his capabilities!

    My view is that ( unless he warned you beforehand ) then its his responsibility to pay someone with the necessary skills to put it right!

    sounds more like he's mixed up the hot water supply and the heating supply lines

    Now that wouldnt surprise me cos the boiler was working fine before he started work, just aswell he didnt get full payment cos il have have to get someone done to inspect the work, thanks for your post.

    Whilst in my view its his responsibility to correct the problem, you should still give him the opportunity to put it right as he thinks best.

    Anyone with such limited capabilities should have a mentor to help him every time he gets into difficulties like this.

    If he can mess up such a simple task then he probably gets into lots of these difficulties.

    What is his reaction to it not working properly???

    This "plumber" should be told what to do, as he is too dumb to figure it out.

    Iv just been under the house to have a look and to my untrained eye it looks like hes hooked everything up correctly, theres no way he could have linked the heating to the hot water so kudos there.
    Im wondering if its a fault with the boiler or the clock, the heating and hot water were independant of each other but now when i switch the heating on the hot water comes on even when its switched off yet the hot water remains independant of the heating???
    and of course the pressure rising is still an issue, theres no airlocks anywhere in the system, all rads bled and the pump in the boiler itself.

    Err, I may be missing something, but as it's a combi boiler, the DHW will be on only when you turn on a hot tap, regardless of what the heating is doing.

    Unless there's something you're not telling us, like you have a Megaflow or somesuch. (Electric flow valve is a bit of a giveaway.)

    If all he's done is remove a rad, replace with another of a different size and repipe for the new rad, everything should work as before.
    Did he drain the whole system?
    Did he balance the system after the alteration?

    Apologies and thanks to all who posted, my lack of knowledge didnt help. The wife started breathing fire and iv just had an engineer down, it turns out it was a faulty clock, expansion tank full of water and an airlock in the system so the plumber is off the hook he did a goodish job, he just didnt have enough knowledge of the boiler. Once again my thanks for posting.
