valve problem

Hi all. I've got a problem where my boiler is running 24/7. The issue seems to be with the Honeywell motorised valves. On 2 of the 3 zone valves, there's no resistance when using the manual lever, so I assumed 2 of the valves were stuck open. However, I've taken the motor off and there's still...

Today I drained my CH/HW. This is a standard vented, pumped S plan with two electric valves, and I'm in UK. I was lucky enough to have a drain valve underneath ground floor, relatively accessible, see pics: However, upon refilling the system, I found out that that valve will rotate...

Hi all I’m hoping somebody can help? We have a towel radiator in the bathroom (pictured) which is leaking from the top right valve. Obviously with current COVID restrictions we thought we would have a go ourselves. Can you please advise the steps we would need to take ie what do we need to turn...

Good evening all, I’m after some advice, my biasi riva compact he mk2 m96a 24sm/c. Has a issue with the heating coming on when any hot tap is been Run in the house. I have done some homework and came to the conclusion it’s the divertor valve. I brought a divertor valve cartridge and fitted it...

Hi all, I believe we have a Vaillant Turbomax boiler although I'm unsure of the exact model number. The pressure has been low for a couple of years but only recently on a couple of occasions it has failed to fire up. I just pressed a button and it switched back on immediately. A gas safety...

Hello, I am going to need to replace the two in my airing cupboard and I've been informed I have to replace them with Sunvics. I can't use other manufacturers as it would mean replacing the valves as well. Is that correct? I have an SZM1802 and an SZM1803. Thanks.

Does one in the land of the free not know about water valves? :D:rolleyes: Skip to 6:00 for the fix!

I have a Honeywell v4073a1039 3 port valve in my heating system and now the hot water and the central heating work intermittently, though banging the valve with my hand seems to bring it back to life, sometimes briefly sometimes until it switches off whereupon on starting again many hours later...

Hi, One of my radiators is not working, completely cold while the others are blazing. I have read that this could be caused by the pin inside the valve being stuck. Unfortunately I cannot remove the old Giacomini head - does anyone know if there is a knack to doing so for this particular model...

in my house we have hot water and heating both on constant, but about a week ago they both suddenly stopped working. the pilot light was still lit in the boiler, so i power-cycled the programmer, mid position valve, and pump in the airing cupboard. i' managed to get the heating or hot water...

Evening all. Think I might be going out of my mind! All my radiators are baking hot - except for one upstairs. It has a valve on it like this (as do all the rads): I've fully opened the tap and both input and output get hot. The radiator remains stubbornly cold. I opened the bleed at the...

As my hot water is from solar I only need the 'central heating' on. But now I find the boiler will only fire up and the central heating work if the 'domestic hot water' is turned on too. It has been fine before but now when I need heating on more it refuses to fire up unless the hot water is...
