    Shower Mixer valve issue

    I want to swap over a shower mixer valve and it appears the previous installer got the hot and cold the wrong way round. The pipes to the valve are fed directly from a Stuart Turner twin pump, is it as simple as changing the outlet pipes over on the pump to correct this issue

    Brittany bar mixer valve fluctuations in temperature

    Shower valve off combi boiler goes hot/cold and is never constant. Does anyone ever “service” these or is it quicker and cheaper to replace whole thermostatic valve? Can’t imagine there’s much to them apart from the cartridge and inlet filters.

    Problems with Drayton MA1 mixer valve

    Hi from a new member and thanks for taking the trouble to read this. Problem is that the water has not been heating.
