After moving a set of draws I've found a spot on my one pipe central heating flow that's rusted and leaking very slightly. I was planning to cover the spot in epoxy repair paste and hoping that stops further damage, but is that a good idea? How big of a job is it to fix this otherwise?

We had two rads taken out to do some insulation. The plumber drained the system, took the rads of and then capped them off. He didn't refill the system, and I don't think he realised that the boiler also fed the HW tank. As of this morning, the boiler won't fire and we have no HW. Having...

I have poor flow through some of my radiators in a one pipe system. The actual pipe is blisteringly hot, and it's almost as hot on the return valve too. Some rads pump out heat, but most suffer from poor flow and the water isn't even getting to the lockshield return. A Plumber came out last...

I've had a few leaking TRV's recently. On the more traditional ones, I unscrew the top cap and then use a spanner to remove the nut. If I remove this cap, I'm left with a spindle and no visible nut. How do I get this thing off?

I was just reading the manual for the two Grundfos pumps I have on the heating system, and the manual suggests using constant pressure mode for a single pipe setup. It was previously set on constant speed 3. My bills are currently £800 a month, so I am desperately trying to make sure...

I have an old Single Pipe Central heating system, being fed from a newish Worcester Greenstar 8000. I've included some pictures of the boiler and the connections underneath it. My first question is...it says 25.5 BAR pressure, that cannot be accurate, can it? Is there a way to double check the...

It's not pouring out but it's a slow trickle of water. I have never noticed this happening before and I'm not sure how long it's been happening. The water tank is a Joule Cyclone indirect 250l. If I turn the red part of the valve, it releases hot water as I persume its supposed to. The water...

Someone has pulled the flush handle too hard and snapped it off from the mechanism. I've tried to google but a lot of the results don't match this type of toilet. What is the actual part called that I need to replace, so I can buy it and find the right tutorial?

I have a Honeywell Evohome, connecting to several HR91 TRV's across the house. The hallways and a couple of rooms don't have TRV's, and the EvoHome controller acts as the temperature sensor for those rooms, labelled as 'Common Areas'. I want the 'Common Area' zone to be able to call for heat...

We had a smart meter installed on the 6th. Since then, the boiler has been constantly ignited, despite all hot water and heating switched off. I think the culprit is a Grundfos pump. I am absolutely clueless on plumping, but need to get this fixed as our boiler is a 50kw unit and gas is...
