    Leak through mixer tap

    Can't tell for sure, but likely that: 1. Using the bath, water does not splash by the base of the taps. 2. Using the shower, water does splash by the base of the taps, and is running under the base of the hot. If the above, try slackening the back nut securing the tap, lifting the tap and adding...

    VIVA Skylo Dual Flush Nightmare

    1. Do you have a syphon, or a flush valve? 2. If a syphon then the WC can leak water into the bowl only if the inlet valve: 2.1 Is adjusted so the water level is too high and the water is gong down the internal overflow into the bowl. OR 2.2 Is faulty and letting water through when it should...

    Leaky elbow in tricky position

    1. Nothing wrong with push fit provided it is used in the right circumstances. I wouldn't use it where its subject to high water temperatures (e.g. secondary circulation systems, within 1 metre of a boiler) or where rodents are not rare. 2. I prefer copper, mainly because I think it is neater...

    Leaky elbow in tricky position

    One possible option: 1. Cut the longer arm (going towards the back wall) about half way. 2. Heat the elbow close to the other arm and separate elbow joint. Reheat elbow end of stub (shorter arm) and wipe off old solder. 3. Use a slip coupling and some new pipe to extend longer arm. 4. Solder on...

    532/I high/low pressure. Fix or replace?

    You have 3 options: 1. Have the pressure vessel in the existing boiler replaced. Assumes the engineer opened the system while re-pressurising. 2. Install an additional expansion vessel exterior to the boiler. 3. Replace the boiler. Hard to say without seeing it but I would try option 2 first if...

    A couple of wash basin issues - removing a back nut from a tap and a slight leak from the waste

    1. That looks like a Vado "Elements" basin mixer. If so, the cartridges can be replaced. The round chrome plated shrouds below the handles unscrew (normal right hand thread) and the handles come with them, revealing the tap works which can be removed and replaced in the usual way. 2. If you...

    Could I use this to prevent backflow in a rubber hose?

    1. All plumbing non-return valves, except the flap type which must be oriented the correct way, are spring loaded, and require a sufficient pressure of water to open the spring. The pressure behind a water softener overflow pipe is very low, and I suspect would not be enough to open the valve...

    Move combi boiler to top of cupboard

    1. Look up make and model of your boiler, look up the installation instructions (internet) and see if there is enough clearance above if you move it up. 2. With the make and model, see if flue kits are available. Bit dodgy if the boiler is of some age, and generally the old flue cannot be...

    Aqualisa 900 concealed shower valve leaking?

    1. It could be a number of things, including the screws which hold the cartridge cover in place or the cartridge gasket. 2. Replacing the fiddly O ring is probably worth doing as a first step. 3. Take the front off and see if that reveals where the leak is coming from.

    Old car or motorcycle inner tube cut to shape.

    Does the shower hose on a bath tap need to have a nut at the end?

    The shape of the end fitting on the hose doesn't matter, provided it's female thread matches the male thread on the taps. Usually 1/2" BSP

    Tap with double check valve, should it be internal?

    1. If it's a new installation, the check valve must be within the thermal envelope of the building. 2. If it's a replacement of an existing tap which itself had a built in check valve, then another tap with a built in check valve is allowed. 3. Water Regulation 15.20 refers.

    Vintage Hot and Cold Tap Washer, What type of Washer it is? Where to buy?

    1. They look to me as if they have had two washers fitted. The larger one which fits into the brass "cup", and a smaller one fitted on top. 2. I'd suggest getting the larger ones and fitting them inside the cups after removing all the existing washers. As Rodders53 states, they will likely be...

    Leaking concealed cistern with no thread on the pipe going to the flush pipe

    If you carefully measure the outside diameters of the part with O rings and your new flush pipe, you will probably find a "Fernco" coupling to fit. If this looks feasible and you have enough access to tighten the clips, remove the O rings and fasten the coupler above the upper groove or between...

    Leaking concealed cistern with no thread on the pipe going to the flush pipe

    1. I've not seen one like that before. Is it possible that the white plastic part with the two O rings is itself screwed onto the more normal threaded end of the syphon or flush valve within the WC cistern? Is it possible to remove the insulation jacket and have a closer look? 2. The Mcalpine...

    Can not find tap gland/cartridge in the right size

    1. 5/8" BSP threads have an outside diameter of just under 23 mm, so allowing for some tolerance I suspect the thread is 5/8" BSP. 2. Its an unusual size for a tap, which are nearly always 1/2" or 3/4" BSP. There are, or rather were, some 5/8 outside taps made. 3. A photograph / description of...

    Fitting Tee in Existing Pipework

    I may have misunderstood what you want to do, but don't forget that normal fittings have a stop at a certain depth for each entry point. What you need is a slip tee with no stop on the "straight through" leg. However, so far as I know you cannot get such a fitting. If this is the case you...

    Noisy Pump

    1. Techflow was acquired by Stuart Turner around 2010. 2. I doubt it is the pipework transmitting the noise. Even if there is little longitudinal room for the flexi pipes, they are still made of rubber which tends to be sound deadening. 3. If you were able to move the base of the pump to the...
