I was under the impression the earth was to protect the cable/flex if you cut through it not the device its connected to as these tend to be plastic nowadays, although the back box is metal so will need earthing

I need to relocate the programmer from inside the airing cupboard to just outside, unfortunately the cable/s are just too short so I thought I'd just replace them. Turns out they are 2 T&E cables with both earths used as switch lines, hence the programmer is not earthed! I've tried a few...

I've hammered a chisel between the head and valve body all its done is bent the head back plate which is now shaped like a banana. The head base will move freely and rotate but the shaft is firm, defiantly feels clipped in somehow. Did they make an all in one unit that couldn't have the head...

yes its got a dimple on the cover and i put it into manual position first. It's locked solid like there's a clip or something holding it?

Yes that's identical to mine, right up to 1:47 where he pulls the cover off! I've removed the 2 screws diagonally opposite each other, but the head is firmly attached to the brass valve body somehow? Any ideas?

Just put my hot water on for the 1st time in about 4 weeks (we've got solar thermal so don't use the boiler much in the summer), and noticed the radiators getting hot. Looked at the 3 port valve and is was really hot to touch. Thought I'd order a replacement head, as it's a newer style 3 port...

I've just picked up a 2nd hand pool heat pump, its a bit tatty but I was told it just had a faulty water flow switch. I have removed the water flow switch and tested it and it appears to be operating as if I move the paddle in the direction of the water flow it's resistance changes and it...

No there is a heat exchanger for the 4000l pool and the solar tubes use the primary coil inside the 200l megaflow tank. I've not put any glycol solution in yet as I don't want to spend money if it doesn't work. On days like today with the tubes in full direct sun the circulating pump will be...

I've been messing around with some 2nd had solar thermal tube collectors I've been given and found. So far I've got 60x 1.8m Kingspan thermomax tubes in 2 30 tube manifolds heating a 200l megaflow cylinder and a 4000l water storage tank I've converted to a hot tub / pool. I've only cobbled...

so if the Americans say to use "kerosene K1 clean burn clear". Its basically the same as clear paraffin here in the UK. I'm assuming that the lamp oil you see for sale in the little 1 litre bottles in garden centres and such is also UK paraffin although the indoor one as you say is more purified...

I'm not sure which category this would go in so I though I'd post it here and hopefully someone can point me in the right direction. I've got a few Aladdin lamps...

Thanks for that. It was kind of what I was thinking but its nice to know other people think the same. Good spot with the photo RandomGrinch

I looked at those and it seems a lot for a 10m bit of cable. The plug on the hoover end I will have to cut of as it goes straight into screw terminals inside and I've already got the 3 pin plug. I can get 10m of 2 core 1.5mm² flex for less than £10 online. It's only an old hoover i keep in the...

I need to replace the cable flex on my Henry/Numatic hoover. I can't find any lettering to identify the old cable but by comparing the conductor size to a bit of 3core 1mm² i've got, it look to be the same, just 2 cores not 3. However the motor is rated at 1000w, max 1200w (from the data plate...

I've got a problem getting access into a part of the roof to work on the chimney and gain access to insulate the roof properly. It's a bungalow with dormers built into the roof where the chimneys are. Basically the jack rafters which are 4x2 are too close together to allow access through so I...

The main oven on our new Smeg range cooker has stopped working a couple of weeks ago. The rest of the cooker induction hob and 2nd oven and grill are all fine, just the main oven seems dead. I removed the back panel and disconnected the main element, put a multi-meter across it and there was no...

I'm after some advise, I'm just planning out a shed/workshop and I've got a load of 100mm polystyrene sheets left over from another job, i was going to put them under the floor so that the floor slab was insulated. I've seen this done for extensions and new builds where it goes on top of the...

the PIR's are along the side of the drive and i walk up and down the drive to test them so they are at 90 degrees to the normal direction of travel. They seem fine when i initially set them up but when i come home in the evening or early morning in the dark and walk or drive up the drive they...

It's not reliability i'm after improving. The PIR's don't fail they just don't seem to work when you want them to and then then they go off all night when a gnat flies past. I'll try a sentinel and clipsal. The load is only 10 3w LED's so 30W and a 300W LED on another one

Can anyone give me some PIR's they have installed and know work reliably, I've tried a few different ones from Toolstation, Screwfix and TLC and they all seem to be a bit hit and miss. They come on and off all night causing a nusience to the neighbours, but when i walk down the drive directly...
