I have an open vented Y-Plan CH system, now 15 years old. The house is a mid-terrace two bed 2 floor house It's been running OK apart from issues with the Myson 3 port valve, sometimes the actuator doesn't turn unless persuaded with a punch! I have noticed the spindle on the valve body was...

... all is fine, I've removed the bolts, rotated the pump head and retightened=... ready for P-Day!

Oh yeah I know that now... I called their tech support just now and a kind young lady told me that was normal. :oops:

Don't fancy taking a new pump apart! I get a little airlock on hw only after a drain and refill. It goes eventually after flicking pump speeds up and down. Cheers

I'll be replacing the old Myson CH pump next month and wondered if a Grundfos Alpha 2L smart pump would be suitable. I have an open vented Y-Plan system, small 2 bed house. The pump flow is from top to bottom. Grundofs' online document indicates not to install an Alpha 2L upside down: on...

Room stat is in the lounge 5 metres from a large double radiator with a thermostatic valve (which I keep on full blast). Heating in house is well balanced. Just wondered if old shield valves were worth replacing :D

Hi I added Sentinel X400 in preparation to clearing muck out the heating system (vented) and after re-filling and adjusting one lockshield, the lockshield failed and couldn't be repaired (the thread for the packing nut on the valve body sheared off). So I had to get a new lockshield, another...

Seeing as they are both likely to fail after a few years perhaps a pipe to pump connector without any valve would be a good thing :roll:

Hi What are best: gate valves or ball valves for CH Pump? Ta

Thank you for the offer - but I bought it today so too late. Tidy airing cupboard here we come... Never thought I should get the boiler serviced twice a year!

5 metres should do it - if I do the same for water pump. About time the airing cupboard was tidied up. Talking of helpful plumbers as you are, one came out on Friday to advise why my boiler wasn't firing up and was due to a struggling actuator (5 years old). I asked if he thought boiler...

Hi The cable for the actuator currently lies untidily on the airing cupboard floor and I would like to put it in some trunking behind the hot water cylinder. Where can I buy cable to extend it? Cheers

Hi Sorry, it was removed long time ago :(

Thank you for your insight, which obviously highlights the need to get a qulified electrician in to check everything out on this kitchen / boiler ring. I have to say the house was built by Wimpy 14 years ago (I have lived in from new) and the MCBs were not labelled in the consumer unit...

Thanks for getting back. . Yes, a blank cover. Thanks.

Hi I would like to add a single socket spur on otherside of a plasterboard wall partition (from kitchen to lounge.) Before I get a sparkie in I wonder what you guys think of the set up. In the kitchen there is an isolator switch to the freezer, my idea being to spur off that. This...

Yes I did :oops: not a combi boiler...

Hmm thanks for that. I have a combi boiler, 14 years old. So the water is coming from the hot water cylinder, would it benefit from flushing out? Cheers

Hi all Has anyone had a red / orange scum build up oni the floor of a bath when the water dries out? Is this some kind of rust? Thanks! Marcus

Hi I had a new exhaust system from cat replaced, everything OK with that. After the new exhaust was fitted, on idle and on accelerating the engine hesitates / misfires and judders a long, worse when cold. Problem was not there before. Could this be the MAF? V reg Ford Fiesta 1.25...
