1-1/4 In Vent Dia. Brass Automatic Vent Valve, 1/4 In Inlet Size is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Works great. I have a small air leak before my pool pump that allows my filter to fill with air over time. Now, the system just evacuates the air on its own and I no longer have to go manually discharge the air with the valve at the top of the filter.It took 5 minutes and a few dollars worth of brass connectors to install.
