Rated 1 out of 5 by 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
Rated 5 out of 5 by Removes air locks fast Heating circulation problems are often due to air locks caused by trapped air pockets at high points in the system. e.g. when a pipe goes up and then down again. The use of this magical air vent in this situation remedies the problem and prevents its recurrence. 25-Aug-2014
Rated 1 out of 5 by Not of merchantable quality One valve leaked immediately after installation, the other failed after 6 months. I now have to drain the system to fit some proper ones. 10-Jan-2014
Rated 5 out of 5 by Maybe little but big job Had a problem with trapped air in the heating system following the boiler change. Advised that this is what is needed to solve the problem, really pleased with it. 06-Jan-2014
