    Cold Radiator - questions regarding valves

    Hi all, I'm hoping someone here can help. The radiators in my living room aren't heating as well as the radiator in bedroom, hall and bathroom in my flat. I've checked and both seem to be free from trapped air (tried to bleed and water came straight out). Now one radiator gets a lot warmer...

    Moved in to bungalow recently and 1 radiator is cold. All the others get really hot when turned on. Gas system boiler, header tank in loft. I tried balancing, turning off other radiators, increasing pump speed, but best I could get at high pump speed is a tiny bit of heat in radiator, barely...

    Cold radiators balancing

    Our upstairs radiators were getting much hotter much quicker than down stairs. To try and balance I altered some of the lock values on the upstairs rads (not fully closed though) this seemed to work and the downstairs rads were much hotter however one of the upstairs rads was now totally cold...

    Some rads cold at the top, and some at the bottom.

    Hi, We had all the rads replaced in the spring. They had this issue from day one but, tbh, I thought once they start getting used in the winter, things might sort themselves out. That hasn't happened. It's a weird situation where some rads heat up only at the top, and some only at the...

    Radiators top half hot & bottom half cold/warm---to do power flush?

    Hi all, I had my new boiler and 13 radiators installed in July last year, but since installed all the radiators always top half hot and bottom half cold or warm. I know that if radiators top half hot bottom half cold/warm, it indicates there's sludge in the system. But as the radiators were all...

    The hole in the slab for cold water shower tap inlet is 1200mm away from where it needs to be. Is this a problem? The bathroom is on the second storey (concrete slab) and it looks like the builders may have put the plumbing for the shower inlet about 1200mm away from where it needs to be. Is...

    10mm not 15mm cold water to fridge

    Divy here thought his cold water feed was 15mm.. so bought a 15mm - 1/4" reducing tee to plumb a fridge. It's 10mm!! I've already cut it so stuck a stop end on. What options do I have as I can't find a 10mm - 1/4" reducing tee... Do I get some 15mm pipe and use 15mm - 10mm reducers ?

    Why hot water copper pipe is 22mm and cold is 15mm?

    Hi All, I have this silly question. Water pressure for hot water is a bit low while cold water has a decent pressure. Why do they put 22mm copper pipes for hot water? It seems detrimental for already low pressure. Best regards
