    Changing a 3 port actuator valve

    My 3 way actuator valve has gone on my central heating. I think it's a combination of the valve motor burning out due to a stiff valve on the pipework. I'm considering doing the fix myself but wanted to check I know what I'm doing beforehand or whether I should get a plumber in, have I missed...

    2 port valve fault finding?

    Hey guys. What’s the easiest way of determining that a 2 port motor has failed? I know that if the stat is calling and the arm is set to open on the valve and the actuator is ok it will fire. Is it purely a case of checking whether 240v is at the brown and orange when heat is called for? Any...

    How long do honeywell two port motorised valves last?

    Ours are lasting between a year and two years and then I have to replace. Is this normal or should I be investigating our central heating system to find out why? Which motorised valves do you recommend I use?

    Three Port Valve bang when heating switches off.

    I have a Y-plan system with a Honeywell 4073 three port valve. The valve is several years old. There is a bypass gate valve across the HW cylinder coil. It is cracked slightly open as it always has been. The pump has always been on minimum speed and has not been changed. Since starting to use...

    Flow rates through 2 and 3 port valves.

Now I can see that being valid if both heating and hot water are called for but if only one surely the flow rate will be the same for both plans? Finally are there any makes...

    Port valve cable extension

    Can I ask what you guys use if you need to extend the cable that comes with a 2 or 3 port valve? I cannot find a 5 core or 6 core that has an orange core. All I can think of using is 3095Y cable and sheathing the black in orange sleeve.

    Honeywell 2 port zone valve not turning on

    There's power going to the valve head but the motor won't activate to turn the spindle to open the valve. The manual override will not activate the valve either. Should I replace the valve powered or Whole valve unit with pipe/spindle attached. My initial thinking the valve motor died and I...

    Hi again I'm on a roll with the plumbing questions today! So here's query #2... We've not used our hot water for quite some time, and it now doesn't work. From what I can gather based on what I've learnt in the last hour or two, I think the problem is with the 3 port motorised valve. When...
