    pumping over when hot water selected

    fully pumped system, sunvic 3 port valve,grundfos 15/50 pump,worcester greenstar boiler. I've noticed recently that the vent pipe to the F&E tank is producing a constant trickle of water when I select for hot water alone or heating & hot water. Heating alone does not produce this flow. I also...

    exposed mains cable behind boiler

    I've recently had a new boiler fitted in a downstairs kitchen. The new position of the flue meant the disturbing of what I believe to be the mains supply to upstairs. This cable was originally just buried under the plaster as it is an oldish house. Now the cable emerges just above the boiler...

    boiler leak

    My 14 year old gloworm spacesaver kfb 50 has began to drip quite a bit from within the body of the boiler when turned on. The engineer that came to have a look said immediatly that it was the heat exchanger leeking, that it was terminal and that I require a new boiler. He did this without...

    basin bottle trap size

    I require a bottle trap for a bathroom sink but the waste pipe is 40mm rather than 32mm. Are traps available which are 32mm basin end and 40 mm waste end? Also, are there traps which push fit on to the waste pipes? The ones I see all seem to be compression.

    how do i attach aquapanel?

    How do I attach Aquapanel sheets to a brick bathroom wall around a shower? Can i just use screws and plugs and if so of what size? The manufacturers seem to prefer attaching them to timber battons but what size should these be? The panels will then be tiled. Thanks.

    which plaster should i use before tanking?

    Which type of plaster should I use to repair an area of around 2 square metres prior to tiling and tanking in a shower area? Manufacturers advise not to attach tiles to base coats so do I have to use a finishing coat also? Do I need to add a finishing coat to a much larger area ( 3 or 4 square...

    render/plaster/aquapanel?

    I've just removed the tiles from around my bath which is bordered by brick walls on two sides and a plywood partition with shower on the third. I plan to replace the plywood with Aquapanel but am not sure what to do with the wall which runs the length of the bath and takes the brunt of the...

    can you move the feet of a bath? (a bit)

    How much leeway or scope for adjustment is there in the feet of a bath? I'm after a new one , maybe a Kaldewei Saniform 1700x750 and am concerned that the feet of any bath I buy might not fit around the existing pipework under there. Can they be slightly moved by a few mm up or down the length...

The fittings and pipe work are all situated in a cramped airing cupboard with the controls and shower head fitted to the...

    hot water/no heating-diverter valve?

    I have a Gloworm spacesaver kfb50, Grundfos 15/50 pump, Sunvic SD 2701 three port actuator. The hot water works fine but the heating won't work at all. I've put the thermostat right up and switched the heating on either with the hot water or on it's own but cannot get any heating. The pump...

    Gloworm spacesaver kfb 50 wailing/whining

    I have recently drained the central heating system several times as I have been replacing some old radiator valves. The boiler then began to make a crackling/creaking noise when in operation which I think was "kettling" due to a build up of sludge in the system I may have disturbed. I got a...
