    I need 3 auto air value for my CH system. Any suggestions to a good quality 15mm product. I was going to buy the unbranded screwfix ones but some of the reviews are terrible.

    Thanks folks.

    Manual air vents with an upstand tube once bled you won’t need to bleed them again

    As shauncorbs says, go for manual ones, theres nothing to really go wrong with them, auto ones are to prone to leaking for very little benefit over manual ones.

    Manual air vents never seem to last 2 mins on a mucky system.

    Prefer a nice manual air vent, nice bit of pipe underneath.

    Put a decent lever valve before the auto air vent. Will make future maintenance easier. They all leak sooner or later.

    As above really. Most cheap AAV's will leak eventually and become a nuisance or do damage. There is a Commercial one I do rate quite highly but it will cost a pretty penny and probably be overkill on domestic. I would go for the manual as other suggest. Once vented a system should not suffer with air issues, as long as it has been installed correctly.
