Rated 4 out of 5 by 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. 9 Sep 2016
Rated 4 out of 5 by good value I have used many of these. Always work. Good value. 12 Aug 2016
Rated 1 out of 5 by 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. 11 Aug 2016
Rated 4 out of 5 by 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! 26 Sep 2015

Hello Totoboy,

Every installation is different due to the varying circumstances of the site and environment.

Therefore we advise that you contact a local tradesperson who will be able to view and assess your particular requirements. They will be able to provide further advice for the installation of the Bottle Air Vent.

Thank you for using Q&A.

Hi Dancingdog,

With a product like this it would be best to refer back to the manufacturer of the heater and make sure that they are happy for this product to fit.

Thank you for using Q and A.
