    DN70 adapter

    Please could you tell me where I can obtain a DN70 (70mm) to 40mm adapter? It is for an overflow so it will not be under pressure. The only ones I can find are rubber adapters 60mm OD to 40mm ID. Thanks in anticipation

    First floor decking

    Sorry to bother you again Woody but I didn't realise there was so much to learn about screws! Screwfix sell a screw (50954) that's specifically for securing chipboard floors to joists. It's 4mm x 55mm (which fits your criteria) and has an unthreaded portion near the top of the shank to prevent...

    First floor decking

    Thanks for all this good advice. I've already bought the sheets of chipboard (sorry Noseall!) and I agree that screwing them down is probably the best option. I've looked in the Screwfix catalogue and although they have an extensive range of screws, none of them mention BS1210. Please can you...

    First floor decking

    I'm building myself a house and I've reached the stage of installing the the first floor decking. The house is weather-tight and I intend to use 2400x600 sheets of 22mm thick moisture resistant T&G chipboard. Someone told me that in addition to nailing the sheets down I should also glue all the...

    Pressurised DHW system

    I'm building a 4-bed house that is going to have underfloor heating on the ground floor, radiators on the first floor and a pressurised DHW system. I would also like to use two sources of heat, a gas boiler and a wood burning stove connected to two indirect coils in an unvented cylinder but...

    Triton T80i Low Pressure Problem

    Hi, I've just completed a minor plumbing repair that was nothing to do with showers but involved turning off the main stopcock. Before I turned the stopcock off, the lady mentioned that the shower head attached to the Triton T80i in the main bathroom was leaking and asked me to look at it...

    Low Voltage Transformer Problem

    Hi BTG, Yes, I did fix the problem. I replaced the old crappy light switch with a good quality new one (which I think was the main problem) and just to be on the safe side I also replaced all the 50W lamps with 35W. The customer said the bathroom was too bright anyway!

    Thanks for all your help guys, I think Deluks' suggestion is probably the one I'll go for.

    Soakaway near concrete raft

    Hi, About 4 years ago I had a detached garage built on a concrete raft. The rainwater from the roof runs into a soakaway that I built about 1.5m away from the raft. The Building Inspector says it is too close and that it should be at least 3m away but it is impractical to move it because it...

    Plasterboard on top of tiles

    Excuse my ignorance Aqua, but what is board adhesive? You advise not to leave any in my bucket so it sounds like something that has to be mixed? I've been on a couple of websites and all I can find is PVA Building Adhesive that comes ready mixed in 2.5L tubs for about £8. I had thought of...

    Plasterboard on top of tiles

    Thanks for all your help. I can't find anything on the internet about Evo-stik 918 tile primer but I have found something called WSE Primer/Adhesion Promotor from www.decoratingdirect.co.uk that is designed to be put on glazed ceramic tiles. Then there is the problem of which adhesive...

    Plasterboard on top of tiles

    I've been asked to convert a downstairs bathroom into a study! This involves removing a very expensive looking 4-piece bathroom suite (dark red) and a shower cubicle complete with mixer shower. The walls are tiled from floor to ceiling and instead of taking the tiles off the walls, I wondered if...

    Header tank

    Someone has asked me to replace the domestic hot water header tank in their loft because it looks like it is made of asbestos (surely its not) and it's started to de-laminate. The house was built in 1948 and I think the tank is original. The outlet pipe is underneath on the bottom of the tank...

    MEM Memera 3 CU

    Sorry, I forgot to thank everyone for all their help. I found that one of the ways on the CU actually has a re-wirable fuse holder and I was going to move it to the spare way at the end of the CU to feed the new shower RCD/MCB unit and buy a replacement 30A cartridge fuse holder for the...

    MEM Memera 3 CU

    I have one spare way on a MEM Memera 3 CU fitted with cartridge fuses (circa 1990) that I want to use to feed an MCB/RCD shower unit. My local electrical wholesaler sold me a 40A MCB (Eaton ALB401) but it doesn't fit. What I need is either a 40A fuse carrier and fuse or a 40A plug-in MCB. The...

    Main trip switch problem

    There are almost certainly more experienced people than me who read this forum who will be able to resolve your problem but as a first stab:- Q1) When your main circuit breaker trips (presumably it's the 100mA RCD that's tripping) does your neighbour's lawn mower stop? Q2) Does the same...

    Switched FCU with RCD - is there such a device?

    Yes I can, and if I can't source a switched FCU with RCD then that's what I'll do. I just thought it would look neater (and save time) if there was such a device. Thanks for your help and if you do happen to find a device in the next couple of days, I'd be grateful if you'd let me know.

    Switched FCU with RCD - is there such a device?

    I'd already looked at these (and the other RCD protected FCUs) sold by Screwfix but I'd assumed that it wasn't good practice to use the RCD test button as a switch. Am I wrong? (The water feature will probably be turned on/off every day.)

    Switched FCU with RCD - is there such a device?

    I want to connect an ornamental garden water feature to the lighting circuit in a garden shed. It has to be the lighting circuit because that's all there is, run from a 6A MCB (without RCD protection) from the house CU. The water feature draws milliamps so I intend to put a 1A fuse in an FCU. I...
