Is there a simple way to drain an indirect hot water cylinder when there is no drain cock fitted to the cold water inlet?

I have a problem with the rcd tripping on the downstairs ring main. I have taken every plug out of every socket and it still does it. It doesn't trip straight away it takes about 5 seconds before it trips. The rcd doesn't trip at all if I have the downstairs mcb in the off position. The...

I have a system that has a pump for the central heating and also another grundfos pump built into the hot water side of the system. The tank is a two part one with hot water below and I presume the f&e tank above. The hot water must be linked to the mains as there is no header tank to feed the...

At present the soil pipe in the house is internal and runs up the corner of the bathroom exiting through the roof. I want to know if there is a way to re route it through the wall (above floor level) in the bathroom and continue up outside the house. This would give more space in the bathroom...

Foe some reason the builder of our estate has used small copper tanks the size of a toilet cistern for the F&E tank of the central heating. The tanks are located in the airing cupboard above the hot water cylinder (which is pressurised hot water). Is there any reason why they used copper or...

I am removing a back door with a 30cm high window above it. I will of course remove the old wooden door and window frame and use brick ties. I would like to know if you can brick up the entire doorway in one go including the 30 cm high window above it, or should I stop part way up and...

I was doing some work at a customers house today and they said the house had only just been rewired. I casually asked about the work and was shocked/amazed to hear that the two electricians who came to do the job rewired a three bedroom house in two days (staring at 8 am and finishing at...

The upstairs lights at my parents house have developed a problem. The consumer unit has an RCD on it and it tripped out. It is fine on every circuit until you switch the MCB for the upstairs lights on then the main RCD will trip. As nothing has been done to the lighting circuit I guess the...

Here is an odd one for you. My brother plugged in his vacuum cleaner about a month ago to a downstairs socket and it tripped out. The MCB didn't flick off but all the sockets stopped working.. About an hour later though they started again. Then yesterday he plugged the cleaner into a...

My neighbour has a Potterton Prima F boiler (not combi) the problem is that they can only get the central heating on when the water in the cylinder requires heating. If you run hot water off or turn the thermostat up then the pump and boiler will kick in and all is well. But as soon as the...

Can anyone tell me if you can run two radiators in parallel from one drop of 10 mm pipework, or does it have to be 15mm to do this? Thanks.

I came across an interesting one the other day. It was a faulty Triton shower rated at 9.5KW. However the MCB for it in the consumer unit was rated at 32amps. (Definitely the shower one as when switched off the power to the shower was off.) Now if you take 9500watts and divide by 240...

Any help appreciated here. The central heating system is fully pumped and has two x 2 port valves. One for the central heating which is motorized and the one for the hot water works with a remote sensor on the tank but shuts using the same system as a TRV (not sure of the correct term for...

Hi, the problem is this. The boiler is a Glow worm space saver mk 2. A while ago I had the problem that if you put it on for hot water only the pump does not seem run and after a very short time the hot water starts venting into the overflow tank and the boiler you get loud banging noises...

Hi, at my office there are 3 radiators at the end of the central heating run that are cold. They all have thermostatic valves on them. The flow and return pipes are hot up until the radiator (which gets hot) before these three but are cold from from there on. Could it be that the...

Hi I want to put some granite tiles on the back wall behind my cooker (which is no problem) but I also want to tile the two inside panels of the cupboard which is bare timber. What is the best adhesive or method to fix the granite tiles to the timber sides. It's only about a meter high of tiles...

Hi, my central heating is coming on when it is not required. When the electronic programmer tells the heating and hot water to come on but the thermostat is down lower than the room temperature the radiators still heat up. I have checked the three port valve and that is moving freely across...

Hi, I want to know if there is a maximum distance that a consumer unit can be installed away from the meter (the property is on the Isle of Wight). The property has an existing fuse type consumer unit (with only 3 fuse ways) in the integral garage. I want to put a new consumer unit inside the...

I need to turn the stopcock off outside my house. It's a new(ish) house so it only affects my property. My questions are: 1. do you just use the long stopcock key and turn the handle clockwise to shut the water off, and do you turn it until it is fully down like the stopcock handle in the...
