thanks for the replies guys. The filling loop was still on a small amount. I drained using pressure relief in the end. Ta

have a feel of the flow pipe coming out of the boiler. If this is getting VERY hot during the times when the boiler is firing then the chances are your pump isn't shifting the water round fast enough. Could be a knachered pump. Could be a fuzzed heat exchange impeding flow. Also - I would...

Vaillant TurboMax 28 combi When the CH is on, the pressure goes up to about 2.8 bar. When things are dormant the pressure is still above the recommended operating thresholds. Is there an easy way to reduce this pressure a bit? Can I just bleed one of the radiators for a bit? What...

Thanks Nige - think I'm going to re-route the pipes and seal the chimney.

Thanks Nige - So if i re-route waste round, is it a tricky job to seal the holes left by the soil pipes?

Didn't explain myself did I.. Actually - its a maisonette.. :wink: I own 1st and 2nd floors. Its not a duct housing the soil pipe - that flows through to the back of the house - but nice theory. Its a chimney. Owner of downstairs currently awol. SO.. 1) Is it dangerous 2) Is...

Anyone out there? Have you all been gassed by faulty chimneys...

Hi all - wonder if you can shed some light. 100yr old terraced house. I just knocked down a stud wall to expand a 1st floor bathroom into where a water tank used to sit (I've gone combi). I have exposed an area of pipework that runs from the kitchen at the front of the house, along the...

thanks kevplumb, thanks chrishutt :oops: had visions of my boiler imploding if I drained DHW with mains water in set to off. never had a combi before - its modern and a scary. cheers!

OK - dumb question so I am really sorry - I did a search but couldn't find it. I have a Vailant 828 Turbomax Combi. I have a leaking HW tap in the bathroom (sink) I also have a stopcock which is so old it won't budge. How can I safely turn off the HW in order to change the tap...

Thanks for the responses. Worked was booked back in March chrishutt. Corgi, yes - certificate, yes. Dudes in Spain until next week so I wanted to see if there was something I could do. Not sure what filling loop is but will investigate. Hot water tap in bathroom has started...

Hi I have a Vaillant 828 Turbomax Combi, installed 3 weeks ago. The pressure was at 1.5 bar on installation. I just checked it and its above 2 bar (2 bar marks the end of its "green" operating range). I wanted to know if it is normal for pressures to fluctuate (maybe I caught it at a...

Hiya Got a new system running off a Vaillant 828 combi. Shower is ok but at some point in the future I want a bit more POWER! 12 inch shower head and corner bath etc. What are the ways of achieving this? Do i need to add a tank, off which I can run a fat pump? Or are there other ways...

"Sorry, there are no adverts for this area"

chris, croydon thanks very much (again) for your help. I think I've got enough free advice from the plumbing trade - its time to put something back so I'm getting a bloke in to have a look. One final question - and I appreciate you guys aren't telepathic. From the symptoms described...

OK - simple question. I had to drain the system to get out some x400 that had been in there for a few weeks. Refilled and added some x200 + x100 via F&E tank. Valve in mid position for refill, bled rads downstairs, then upstairs, then pumps. Boiler fired for about 1 minute, then off...

hi gasman the 22mm coming off the left of the air seperator is the output from the boiler, which is a floor below the pump room, in a kitchen. Can you be more specific? What is wrong with the setup? Thanks

Hello again. Its been "working" for about a week on timed CH+HW, but when the heating comes on in the morning the rads all make a kettling type noise (maybe transmitted from boiler?). Pump on 3 (fastest), Boiler (Thorn Apollo) on high The boiler itself is cycling quite rapidly - on for...

Wo hoo! :D Experts in disagreement is always excellent to behold. Guys - thanks very much for your help. I will be printing the entire thread and settling myself in for some serious head scratching over the w/end. Well - an update. I left the system on its boiler-low, pump-medium...

Ha yes this is dragging on a bit isn't it?? At least your hair isn't frozen to your forehead though (mind you - you are from oop naarth aren't you. Nothing wrong with that.. :? ) OK pump is right way round - an expert fitted it. 3 way valve - the pipes on each side are getting hot...
