auto air vent valve this does what is says it does with no problem.. invaluable if you have a trapped air problem 15 Jan 2015
good 15mm bottle air vent It was easy to fit and certainly lived up to expectations. Although it was inexpensive the quality looks fine, as far as reliability goes we shall have to wait and see. 9 Nov 2014
Plug'n'play Bought as a replacement for an identical (?) valve fitted five years ago, which had begun to let water vent as well as air! The replacement was straightforward to fit and appears to be working fine. However, if the earlier valve is identical, I'd question whether the new one will prove to be reliable. Can't be sure it's identical, because Screwfix has a habit of changing suppliers for commodity items, so I may be being unfair here! 4 Nov 2014
Leaking fitting I tried fitting one of these to vent an up and over section of pipe on my shower to replace a manual air vent. It fitted easy enough, however it leaked water straight away from the air vent valve on the top, so I had to screw in the plastic stop valve to prevent the leak. Then having read all the other reviews for the product realised other people had had the same problem so I decided to return it, Screwfix refunded the cost without problem as usual, well done Screwfix. I replaced with another fitting from reputable manufacturer from a plumbers merchant, no problem with that one, very little price difference as well. If you use these I'd keep a close eye on them after fitting. 12 Oct 2014
