    Which plug to screw fix into ceramic tiled plasterboard?

    Hi This will be to put up cabinets, towel rails, shower rail etc. I have looked at the plasterboard fixings that are available but the tiles are approx 9mm thick so I would have to drill a big hole through the tiles and another smaller hole through the plasterboard. Not sure I can manage...

    Warm Water in Cold Cistern!!!

    Masona, it would be ideal and then I could fit a twin impellar booster but i couldn't get a supply from the cistern to the taps without major disruption and messing up existing decoration and flooring. What I hoped would be a fairly simple job has turned in to a right royal pain in the ass...

    Warm Water in Cold Cistern!!!

    Any views on whether the eq. valve is faulty and should be replaced or go with the check valve? Which of these would be suitable? No1: http://www.plumbworld.co.uk/344-1881 No2: http://www.plumbworld.co.uk/344-1884 Thanks again for all the help.

    Warm Water in Cold Cistern!!!

    Sorry to question your recommendation but I just want to be sure I get it right.... If the pressurised cold is going into the eq. valve and passing across the valve and back down the hot supply pipe, if the check valve is fitted after the eq. valve and right by the mixer taps, surely it will...

    Warm Water in Cold Cistern!!!

    Hi Rob884 Do you mean after the eq. valve and before the shower or before the eq valve? I suspect the former as it seems to be the valve that is at fault? Anyone know whether I have a faulty valve? Seems odd that it should do this considering the purpose of the product...? Many thanks.

    No Hot Water after draining down system

    I've had a similar problem. On the pipe that supplies the coil, I have a T junction with a vertical pipe and an automatic air valve. Strange place to put one so I suspect it was installed to overcome historical problems. I took the valve off and connected a hose to the pipe and forced cold...

    Can I use a Twin impellar pump to boost hot pressure only..?

    Right... The twin pump has gone back and I've ordered a single pump and the Pressure eq valve. They should arrive during the week and will be fitted next weekend, assuming Baby doesn't put in an appearance in the meantime! I'll let you know if it works.... Fingers crossed. :?

    Can I use a Twin impellar pump to boost hot pressure only..?

    Thanks for all the replies. From what you have all been writing, as I can't get the cold supply in without lifting flooring, T&G Floorboards etc it seems the easiest practical solution is to take the pump back and get one of these https://www.plumbworld.co.uk/0-298 and run the hot...

    Can I use a Twin impellar pump to boost hot pressure only..?

    How about if I pass both hot and cold supplies through one of these and then through the pump? http://www.plumbworld.co.uk/5-230 Or hot through the pump in parallel, then into the valve. Cold direct into the valve... As you can see, I am out of my depth here and have a 38 weeks pregnant...

    Can I use a Twin impellar pump to boost hot pressure only..?

    Me neither! I assumed it would be gravity... Should have checked it first! What do you think of the connecting in parallel idea?

    Can I use a Twin impellar pump to boost hot pressure only..?

    Thanks Watersystems. Just to clarify are you siggesting: Split the hot supply to 2 pipes. One to each side of the pump. Bring the output of the pump together into 1 pipe. Fit the hot and mains cold to the pressure equlalisation valve and then feed to the mixer tap.... FWIW I have a tank...

    Can I use a Twin impellar pump to boost hot pressure only..?

    I have bought a twin impeller pump to boost pressure in a first floor bathroom shower (via mixer tap) Its a ShowerFORCE Turbo 2 from B&Q. Having plumbed in the hot, I've just realised the cold is mains fed! (Never assume!!) Can I just use one side of the pump to increase hot pressure...
