Rated 4 out of 5 by from Bottle air vent Bought this to vent my destratification pump on hot water cylinder worked perfectly as soon as I opened up the isolating valves. Great value looks well made.

Rated 1 out of 5 by from A liability - do not use First time I've not fitted a Callefi AAV (from Plumb centre), I thought I'd try a different cheaper brand, what a mistake...... Fitted this cheapo AAV 4 days ago, I then get a call from the customer saying that water is pouring from the top vent. Not impressed at all, I'd understand a weep after a year or so as these are almost a consumable, they don't last long, but 4 DAYS!!! As the title says, a liability, pay the extra few quid and go for a known brand form Plumbs or the like.

Rated 4 out of 5 by from Good value - hope it lasts! Needed in a hurry, so no time to shop around for a specific brand. Some reviewers have mentioned leaks, but who knows whether this is the same make? We'll see.... Screwfix are usually very good on returns though - but it's still hassle!

Rated 5 out of 5 by from Very good quality I was pleasantly surprised at the quality of this unit. I fitted it to help limit the amount of air in a Client's old CH system when refilling. As a word of advice, I fit this after an isolation valve in case it ever does start to leak or isn't needed.
