Would anyone be able to recommend a shower tray repairer who does not charge an arm and a leg? The shower tray, since fitted a year ago, has developed two hairline cracks around the waste, which is in the middle. The tray sits on plywood, but is not well supported (fitter used foam), and in...

In the UK, incoming water and gas have been plastic for decades, since at least the 80s. Then it was black and yellow, now it is blue and yellow, but plastic all the same. In the TN-C-S supply, which I assume is what I have in the UK, the E only exists as long as the supply's N is intact. If...

Yes exactly. The supplier's N gets disconnected away from the house. The house's N and E are intact and shorted together inside the meter's housing. The house's own E, in my case a rod in the ground, obviously has some resistance, which has not been noticed, not until the supply's N got...

It was my bad description. I was trying to describe that the supplier's N got disconnected away from the house (overhead cables). I was also trying to describe that the supplier's N joins the house's N and the house's E "at the meter" (3-way connector inside the enclosure which houses the...

It happened to us! I did not know this could ever happen. Supplier's neutral snapped off away from the house. We did not realise. For many days some people were getting mild shocks in the shower when touching the shower tap, but nowhere else. Finally, one day, we got a *much* larger shock in...

Pumping from storage tank into house. The pressure switches are mechanical and adjustable, from what I understand.

I have a 50L expansion tank, and have bought 2 pressure switches (in the post). I have a non-return valve at the pump input, and a 6 bar pressure valve at the pump output.

I want to detect "no water reaching the pump" in general, so as not to run it dry and burn it. It could be an empty storage tank, but it could also be a closed valve or a blocked filter etc. For that I *think* I need another pressure switch to break contact at low pressure, rather than make...

It is a normal water pump, 1100W, intended to take water from a tank (about 900 litres) and feed it to the house. The tank is about 1.5 floor levels high and there is enough gravity pressure to run the ground floor taps, but not upstairs. The tank is needed to alleviate water shortage related...

What happens then? Edited title to clarify it is the electricity company's neutral at/near the meter, or somewhere away from the house

I have now realised the switch/controller (WAPS002) is not possible to adjust manually, and it is set at the factory for 10 bar... I need to buy an adjustable controller.

I have a 1100W water pump and a water pressure switch which fails to control it. The switch supposedly starts at 1.5bar and stops at 10bar (it is not clear when it stops, but it says "10bar, 10A". The pump can never reach 10bar, and a good thing too, and so the switch never stops it. I would...

It was not teed-off my pipe, it appears it ran from the street and under my drive, for about 30 meters, then veering off under flowerbeds and terraces into the neighbour's land, under his drive and eventually to his gas meter. It is unreasonable to expect myself to know and take precautions...

I presume this was done in the 80s when the two houses (mine and neighbours) were originally built. Someone at that time must have given them permission. I will email them yes.

If you recall, a couple of weeks ago we broke through a yellow gas pipe. The gas pipe fed a neighbour's house, and its presence was unknown to us, as it travelled a significant distance under my driveway, which is a very odd thing as the neighbour's house has its own driveway. The pipe...

If I am not mistaken there is no requirement for having fans permanently operating. I could have vents over all windows and keep them shut, and could have extractor fans in utility rooms, kitchen, bathrooms and keep them all switched off.

The ground is sloping upwards to the left of the photo. There is a terrace/flowerbed on the left of the photo and a retaining wall (which I am rebuilding). They originally passed the pipe "under" the terrace. I removed part of it and exposed the pipe. Without the flowerbed the pipe is above...

The glove was used to stop any dirt going into the dead part of the pipe in case they needed to connect it back. On the live side of the pipe we used a yellow end cap fitting I luckily had lying around. But gas pressure is very low, I think it is like 60 mbars before the gas meter compare this...

And why do we need a utility room fan, come what may? We do not cook in the utility and we have window and door.

SGN said are coming tomorrow to disconnect this gas pipe completely and dig out a new path to service the neighbour (as it should have originally been). I hope they fix it tomorrow! Currently they left it with barriers all around (exactly where I am digging my new wall foundations).
