    Should I drain my cold water tank?

    I'll be going away on a short holiday soon, but I'm concerned about my pipes or cold water tank freezing and bursting in the cold weather whilst I'm away. I'll be leaving the heating on in the house to reduce the risk, but I'm considering turning the mains water supply off and draining down the...

    Insulating outside copper pipe

    I've got a short (1 foot) run of 15mm copper water pipe outside, along an external wall. It goes between a spur from the outside tap into the conservatory, where it feeds the washing machine. At the moment, it's uninsulated, but I want to protect it before the bad frosts arrive. Do I need...

    Cracks in external render

    I noticed a decent sized crack in some render on the outside of my property this morning. We have a balcony on the first floor of our 1900s brick house, that sits over a bay window on the ground floor. It's the ceiling of this balcony area that's cracked. I don't know what the render is bonded...

    Is my CH system sealed or not?

    I've just moved to a new house, and the plumbing system is completely alien to me. I've only ever used combi systems with TRVs on radiators before, but now I've got a hot water cylinder and a cold water tank (but no immersion), no TRVs and a room thermostat. I think I understand how this...

    no hot water and low pressure

    Well, the pressure gauge on the boiler is there to indicate the pressure in the closed central heating system. 1.5 bar is about right when cold - it may well rise to 2 or even 3 when the heating's on. The fact that the central heating works fine helps to work out what the problem might be -...

    Cold radiator

    I had a new radiator installed yesterday in the bathroom - it's a Hampton towel rail radiator, see here - http://www.plumbworld.co.uk/0-2438 It replaced an old towel rail that was going a bit rusty and was past its best. Because the new rad was a slightly different size from the last one...

    fitting bathrooms

    My problem was that I had to remove a partition wall simply to take the old bath out, and then make good the walls to a vaguely reasonable standard. Plus the rest of the part-tiled walls had to be made flat for new tiles to be applied. Then the new pipework, assemble the new fittings and remove...

    Leaking soil pipe

    I'm in the midst of installing a new bathroom suite (and it's taking an absolute age - I can't believe how much work is involved) and everything seems to leak. I'm replacing the leaky joints in the pipework one by one, but the leaks in the new bathroom appliances are a bit more of a problem...

    Check valves/non-return valves

    Thanks - I'm only thinking of fitting these to the pipes in the bathroom, so I don't think this will apply?

    Panel showers and combi boilers

    Is it possible to use panel showers with a combi system? There are a few at Screwfix - here - all of which claim to work with combi boilers provided that the pressure is about 1.5bar. I have a Worcester Bosch unit - I think it's a 24i, and so would supply hot water at about 9.5 litres per...

    Check valves/non-return valves

    I understand that these valves only allow water to move through in one direction, and so prevent "backwash". Is there any merit in fitting one of these to every pipe immediately before it goes into an appliance, e.g. shower, toilet, sinks etc.? Would it reduce water hammer, and prevent the...

    Tiling a bathroom

    I'm about to retile the bathroom. I'm planning on stripping the existing tiles out and simply retiling over the surface underneath them (which on three sides should be concrete or brick, coated with plaster and old tile adhesive, and on the other side will be plasterboard). I would normally have...

    Best type of connection?

    I'm about to refit our bathroom, and I'll completely replumb the place. I've used both soldered joints (the type that come pre-soldered and which you just clean, flux, heat with a blowtorch and add more solder to) and compression joints, but never pushfit/speedfit etc. What are all the...

    [b]Dripping noise in radiator[/b]

    I have this problem, and it does coincide with the boiler going off; I've always assumed it was just the pipes contracting as they cooled and making a sound like dripping. Am I wrong, and is it anything to worry about?

    Replumbing a toilet cistern

    Sorry, I'm not being clear. The cistern is boxed into a cabinet - it's the cabinet that I'll need to drill a hole in, not the cistern itself
