Rated 5 out of 5Â by catweasle 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.

One valve leaked immediately after installation, the other failed after 6 months. I now have to drain the system to fit some proper ones.

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.
