Thanks very much boilerdokto. I have a question: in the installation instructions for the syphon it says "Note: Do not use lubricants or sealing compounds." Just wondering why they say not to use silicone grease and you recommend it? A thought..... would I be right in thinking that the...

I have recently had my 2 year old Worcester greenstar 30si serviced. The syphon was quite dirty so was taken out and cleaned. The day after I noticed a drip from the bottom of the boiler. Investigation showed the syphon leaking from where it connects with the sump, trickling down the side...

Thanks for the advice one and all.

Fair point that they do own the Worcester... I guess in dog terms you could probably say the it's a cross between a British Bulldog and a German Shepherd! Thanks for the advice. What makes the Drayton RF's so bad?. I've heard the (American) Honeywells are pretty good.

I'm looking to get a programmable RF room thermostat to connect to my Worcester Greenstar 30si combi boiler. Being a patriotic chap, I'd like to get something UK made or from a UK company. The Drayton Digistat+3RF...

I'm looking for a low-mid priced TRV. Ideally British made. I hear the Drayton TRV4's are highly recommended. But they are a bit pricey at £18 each...

I have to change a few leaky rad valves that tightening/packing the gland nuts hasn't fully resolved. If anyone could be kind enough to fill in the blanks it would be most helpful.... 1. From what I've read, a rad should have a lockshield valve and a control valve. Is this the same on...

I did the PTFE repair on the suspect valves, turned all downstairs rads off and pressure stopped dropping. Have turned rads on one at a time and I have two suspect rads that I will replace the valves on. So, phew, looks like it's not the pipework in the screed.... this time.

Bit of a long lost this one... so hope you don’t get bored :) We've had the pressure dropping in our sealed system for the last couple of months. It's ranged from between 0.5 and 2 bars depending on how much we use the heating. The more the heating is on, the better it seems. The old...

I loosened the gland nut, twisted some PTFE tape into a strand and packed it in tightly round the base of the spindle. No leak now. Thanks chaps.

Long story..... but, in short, I'm trouble shooting the pressure dropping in a sealed system. If have turned off a few radiators. If the rad valve is leaking around the spindle, would the water be coming from the radiator side or the pipework side? Or could it be either or both?

I'm wondering if I might be better going for a new boiler?

I posted over the weekend regarding my Ravenheat CSI 85 condensing combi losing pressure. //www.diynot.com/forums/viewtopic.php?t=202613 I got an engineer round on Monday who really didn’t have a clue what he was doing. I was hoping he could confirm if the cause of the leak was the...

Ouch... the parts £145 on ebay http://cgi.ebay.co.uk/Ravenheat-CSI-Condensing-Heat-Exchanger-0002SCA06005-0_W0QQitemZ220376796708QQcmdZViewItemQQptZUK_Home_Garden_Hearing_Cooling_Air?hash=item334f7b0e24 Any idea how long removal, test, refit would take?

Was it the fact that I didn't go right up to 2bars or did I misunderstand something else? It didn't really seem to want to go higher than 1.9 and there was a lot of creaking. Just to be crystal clear, this is what I did: 1. Bleed all rads 2. Turn off electricity supply to boiler 3. Pump...
