Leaking UFH Manifold

[John_C]

Hi, we have a leak from the underfloor heating manifold. It appears to be leaking from one of the thermal actuators (please see photos). It’s leaking about a cupful every day. So far, I’ve talked to about 10 local plumbers:–

• Contacted original installer. The admin person kept telling me that the boss would come back to me with a call-out appointment. Still waiting 3 1/2 weeks later.
• One plumber came out, said he’ll order some parts and get back to me – over the course of last 2 weeks, every time I called, he said he didn’t have the parts. Stopped taking my calls.
• Another took details, and said he would get me a quote – 5 days now - nothing!
• Arranged call-out with another plumber – he never turned up for the appointment yesterday.
• Awaiting quote from another company.

Can someone please advise:

• What may be the problem – is it the actuator, the manifold, or some sealing component (o-ring or washer). If it’s simple, I’m tempted to have a go myself.
• Recommend a capable and reliable plumber in Cheshire who’s not going to send me around the houses.

Thanks in advance.

Thanks. Does the gland come with a new actuator? The Uponor 1013006 on there is now superseded by 108773. Will it be worthwhile replacing them?

Actuators are seperate, if it still works you don't need one
