    Water pressure low upstairs

    Put your hand on the top. There'll be a big plastic cap not a little tyre valve cap. These sometimes pull off rather than unscrew. The schrader valve will be there below this cap. Tap the EV with your fingernails at the top... Does it ring or sound dull?

    Water pressure low upstairs

    Then it may be that it is blocked or has failed. There's a gauze filter inside. That can be checked (sometimes easy sometimes not). Also Air charge on EV should be checked... Shut off cold feed to uv, open hot taps and use a tyre gauge to check EV pressure. Regen as necessary.

    Water pressure low upstairs

    Have you noticed a drop in pressure/flow at the kitchen cold tap recently? It's fairly likely that water authorities have been reducing network supplies due to the drought conditions recently. As someone joked to me yesterday... "anyone who's disposed of a body in a reservoir must be very...

    Help Identify This Pipe Type

    The inserts were redesigned to provide a "positive stop" ensuring pipe is pushed fully home into the fitting. When you turn the fitting around the pipe you should be able to feel those bumps on the face of the insert undulating which indicates proper assembly. Personally, I don't like the...

    I take it you don't have an unvented hot water cylinder, your boiler being a combi doesn't rule that out!

    Gunge in 40mm pipe

    Find a way to connect a washing machine hose to a cold mains tap and onto the 32mm waste... I've done it with a mixture of bits from my van stock. Then you can connect mains to the drain and flush it through. Or just stick the end of your pressure washer lance into it, make it watertight and...

    Worcester Bosch Greenstar 4000Combi Boiler PRV

    If you've had a condy pump fitted, those external terminations are fairly likely to now be redundant. If you shone a torch down into the floor directly below the new discharge pipe, you might be able to see where the old one was cut and is still there. Could also put a wet vac on it and go...
