please get some help. no, you can't do this because in the switch, the red is live and the black is switched live to the light (not neutral). Connecting up like this wouldn't cause the power to trip, it just wouldn't work or two lights would be working in series :shock: so you must've connected...

socket outlet heights only apply to new construction, you can match the existing height in your house.

If it was wired in the 60's, is the cable grey PVC or grey rubber? If it's rubber there may be some real problems. The later grey rubber cables tended to hold out a lot better than the black VIR ones though, so they may still be ok. Otherwise, it just isn't earthed, so any light...

Over time, I'm CERTAIN a HepvO trap will get a nice layer of dirt, grime and hair stuck all over the rubber flaps, and stop working, that or the rubber will perish with all the hot water, bleach e.t.c.

When I first installed a fan duct, I made the same mistake everyone else does, and used that white vinyl duct through the loft. In the winter, water started dripping through the ceiling (just the moisture in the warm air from the room condensing on the walls of the cold duct through the loft...

yes, you literally remove the 40mm waste from the trap, and slot in the AAV inline, as it drains, it allows air into the pipe, no more gurgling and sewer smells

That's reinforced concrete isn't it? You can get it tested for about £50, just google "asbestos testing lab" in your area, and send them a sample if you're worried

I have about a half dozen like this in my kitchen, its been that way for 5 years

it's just common sense really. How would it be any different to putting one of these over it? http://www.screwfix.com/p/halolite-downlight-insulation-guard-220mm/97932?kpid=97932&cm_mmc=Google-_-Product%20Listing%20Ads-_-Sales%20Tracking-_-sales%20tracking%20url&gclid=CNHpsd7A0LgCFSTKtAodPEwAzw

Dunno if you still need help with this, but I'm a bit of a pro when it comes to ducting :) The duct should be 125mm for that extractor. You need to use proper foil duct tape like you mentionned (Duck tape isn't duct tape, and neither is PVC electrical tape!) a pvc duct hose is no good (it'll...

Simon, thanks for all your help. Big learning curve. I will be hacking into my airing cupboard shortly. Going to attempt to put all the pipes in a nice neat series, supported by unistrut channel and munsen rings something like this lol. I'm a bit obsessively neat. wish me luck.

OP, is your cold tap water warm, brown and murky? If not, just replace the ball valve (s)

lol, only if the boiler header is higher than the cold storage tank and the coil has corroded in the hot water cylinder, (the cold tank is full of warm brown murky water) or someone converted the boiler loop to a pressurized one with expansion vessel and filler and left the header up there doing...

guffed? Is that a technical term? lol

I did this in my own home. It's obvious really. A huge metal RSJ will very quickly dissipate the heat from a halogen downlight. What do you think's going to happen to it? It's not going to catch fire lol. The space requirement is for usual circumstances where it could be in close proximity to...

simple air admittance valves inline with all the traps will prevent syphoning. "anti-vac traps" often do nothing, just use a 32mm AAV instead. These work brilliantly: http://www.wickes.co.uk/invt/424904/?source=123_75 http://www.wickes.co.uk/invt/424903/?source=123_75 These have to be...

replace both ball valves. The large tank provides gravity-fed potable water for the hot water cylinder and taps. The ball valve that fills it has seized open, causing it to overflow. The small tank is designed to fill up the radiators and heating with water (and should be full, with inhibitor...
