Hi, What is this device? 22mm inlet. . From memory I think it comes from the cold header tank. I think it dates back to about 1985. Thanks!

I've stripped out the kitchen and found this behind one of the cupboards. It is back from when the house had an old air ventilation heater system I think. Not required anymore and has been blocked up as shown presumably for many many years. There was a few mould spots on the back of the...

Every few weeks at the moment I notice that the cold water flow upstairs is getting slower and slower until it stops. I have a CWT in the loft, 22mm feed comes out and down into the airing cupboard. There is a tee at about shoulder height with 15mm off the side that feeds into another gate...

Hope this is the right forum, I need to vent a tumble dryer through a single thickness wall that has been tiled with 16" large tiles. I have a 107mm diamond core drill bit designed for going through walls and works well when I have used in the past with my makita sds (with clutch). Im...

I want to have 2 x 1g 35mm box with 3 switches each 2 way switched from either end of the room. Im concerned about cable density in the back box so was considering fitting 3 x 3 core +e 1.5mm (because i have plenty) to each switch and do the rest in a wago box / in ceiling rose. This would...

So I'm chasing out for a rewire. Reusing existing fittings where feasible, but cannot decide about this one. New chase down to work surface done. Note the old cable going off diagonally at 7 o clock.... White socket bottom left i have reinstated as I found the ring main there hidden...

I am new to soldering with a blow torch (I'm much better with small electronics) , and have been replumbing a radiator. Everything was going fine until it came to joining the new pipework to the old. I thought that a bit of moisture in the pipes may be the issue, so ive blown out as much water...

I am planning on removing a radiator in the living room and moving the pipes to a second radiator in the hallway. System is an old boiler, immersion tank and cold header tank. Current piping is 15mm copper. I was planning on chasing in the new pipes from under the floor boards on 1st floor to...

Is it notifable work in England to fit multiple LED spot lights to replace a single light fitting in a kitchen and dining room? I think i have concluded that it is just an amendment to an existing circuit, a kitchen is nolonger a special location, im in England rather than Wales, and the...
