    With no visible nut, how can I remove waste

    1. Click clack wastes, in my experience, rarely work for more than a year or two. 2. If you are really lucky, you might be able to unscrew the fitting from inside the basin. This will be relatively thin, probably chrome plated, metal with five or six holes in it. Normally this is held in place...

    Changing Kitchen Tap.

    If you have a tank fed system for the hot (cold almost certainly mains) turning off the stopcock will not turn off the hot water. To turn off the hot you would need to close the valve (if any) feeding cold water into the very base of the hot water cylinder.

    Fully Pumped Sealed System / Potterton Suprima 60L / Replace expansion vessel?

    1. Central heating systems without a feed and expansion (F&E) tank but with an expansion vessel are called sealed heating systems rather than unvented heating systems. 2. Hot water systems without a vent (generally over the cold water storage cistern CWSC)) are called unvented hot water (DHW =...

    How much stored hot water

    Depends on how much they are used, how they are heated, heat recovery time.

    Any ideas how to fix this leaky tap and what the part is called?

    An update to my previous post. Armeg "jaw droppers" do not have a spanner to fit the spout's back nut so not suitable for that part of the job.

    Fully Pumped Sealed System / Potterton Suprima 60L / Replace expansion vessel?

    1. As its coloured white, that is probably the expansion vessel for an unvented cylinder, not for the boiler. 2. If for an unvented cylinder, there should be a tun dish near the hot water cylinder through which any drips should be visible. 3. If the drip is coming from a copper fitting outside...

    Any ideas how to fix this leaky tap and what the part is called?

    1. That's what is known as a three hole tap. I find them difficult to work on. 2. Unless you are a pretty experienced DIYer and have a good set of tools, I'd recommend getting a plumber to do it. 3. If you intend to DIY it you are likely to have to do a fair bit of dismantling to get at...

    Stumped - closely coupled cistern has no holes for donut bolt-on kit

    1. Not all cisterns are fitted with bolts through the base passing through the back of the bowl. 2. The alternative is a metal plate. This is oval shaped, has a large hole in the centre for the pipe and a slot in each of the "wings" of the oval. 3. These have square shanked bolts. You fit the...

    Odd size radiators

    Where is the water dripping from? Photo of drip and of boiler filling loop would be useful.

    Odd size radiators

    1. If that tape measure in your picture shows the length of the existing radiator, it is 4' 2 1/4" long, not 5' 2". Equivalent to 1,276 mm. If you got a 1200 wide, you would need to "make up" 76 mm. One 1" and one 2" extension = 76.2 mm, so should do the job. Not symmetrical but you might be...

    Potterton Boiler Valve Configuration.

    1. There are two valves with blue handles. 2. The one closest to the yellow handled (gas) valve is the one I refer to as the inner. 3. These valves are normally: 3.1 Off (closed) when the handle is at right angles to the long body of the valve. 3.2 On (open) when the handle is parallel with the...

    Leaking from outside boiler drain after refilling central heating

    1. What is dripping? 1.1 The outlet of the pressure relief valve. Usually copper turned back to a wall with an elbow. 1.2 The condensate pipe. Usually white plastic and should go to a drain, preferably internal. 1.3 A drain cock attached to the boiler feed or return. 2. If 1.1 then check...

    Screw in the middle of bath plug

    1. That screw is what holds the waste fittings in place. There is no "hair trap" below it. 2. If you did not unscrew it fully, and it has screwed back up fairly tight, you shouldn't have any problems. 3. If you are unfortunate and there is a leak, the options may be: 3.1 Remove the bath...

    "Daisy-Chaining" switches/ supply for two immersion elements

    1. Almost certainly not OK. 2. From your description it would be possible to have both immersions running off one supply from the consumer unit. 3. This would give a load of around 26 amps, each normal immersion heater being 3 kW. This could lead to: 3.1 Overheating of the cable from the...

    Air lock i think

    Sounds as if the pipework between the Feed and Expansion (F&E) tank and the system is blocked. Try running a magnet over the pipework starting at the outlet from the F&E and working down. If it seems to stick in places, that is likely where the blockage is.
