A supplementary question: Should I apply a small amount of low modulus clear silicon in the butt joint? I've seen conflicting advice, advising a completely dry joint or using some silicon near the top of the joint. Thoughts?

Cheers, reason I ask, Apollo worktops instructions use glue, which confused me. I just wanted it confirmed Ta

Folk, very quick question: To glue a 90 degree butt joint on solid wood worktops (using biscuits), or avoid glue and use a dry joint? Thanks

Thank you - well if there's anyone in West of Scotland wants a small job, let me know! Parts and fittings supplied :-)

Thanks, and yes that looks like the problem. Without ripping walls and ceilings apart to move the F&E pipes, I think a sealed system looks like the best and possibly the simplest answer?

Apologies, when I started emptying the loft and airing cupboards, I mistook other pipes for the F&E pipes. The feed pipe vanishes into the floor in the airing cupboard, and the expansion pipe looks like it goes into a pipe chase that runs through my bathroom. Sorry for misleading in earlier...

Has a combined feed/vent or feed only alteration (with air separator) been suggested. No I haven't considered that.... seeing the photo of the expansion tank,it looks like a short open vent pipe liable to sucking & spitting water. The vent goes quite high into the loft, but yes it does sucked...

Sorry, yes both pipes run beside each other into my airing cupboard and connect quite close into the system. To be honest, I've had this air problem for years in towel rads, however I recently fitted a new towel radiator in my utility room, which seems to collect much more air. It's the furthest...

Thanks mate, done all that. Pump is on minimum and pipes are clear.

On start up from cold, the pump sucks around 3" from a bottle half filled with water from the overflow, then after a few minutes, some water squirts back in. (See my other post on this). This is the probable cause of air being sucked in and down the vent pipe.

Mines is a strange one, it's really only a towel radiator in a utility room, and same in the en-suite. I've posted details in another thread, but couldn't find anything conclusive.

Tried mate, but couldn't establish where air was getting in. Posted previously on this.

Picture of f&e tank in loft, intention is to use 22mm copper for pressure relief line using same cut out in soffit. The pump is around 3M below the f&e tank.

Thanks mate, I'm going to get the Altecnic 18 litre kit, which has the expansion vessel, pressure gauge, pressure relief valve and filling loop with n/r valve. My loft is easy access, so going to keep it all up there. My GS mate reckons using the existing f&E tank feed pipe will be fine, and...

Thanks for that, sounds encouraging!

Thanks for your input, but I have had issues with air getting into the system. You're lucky I guess. So back to my question.....

Thank you for that. Many of my radiators have been swapped out, but understand risk of leaks etc. Last question; for space reasons, I'd like it fitted in the loft where the current F&E tank is, would that pose any problems?

& Just seen this, same boiler and exact same fault here. Flow switch is a magnetic swing micro switch. Mines had become gummed up with iron oxide particles and had seized. Took various engineers few visits to fin the fault and fix it.

Does anyone have a link or could assist with assessing size for the expansion vessel? It doesn't look as though it'd be too expensive. My boiler can be used in a pressurised system, and I'm keen to convert to a sealed system to stop air getting into rads, see my other post. I've got 12...

Excellent thanks. I think I'm going to investigate this further. All the rad valves are no more than 3 years old, and most of the radiators have been replaced. Could the expansion vessel, filling loop and pressure release line be fitted in the attic? That is, smply fit the filling loop onto the...
