Taco 400-4 1/8-Inch-NPT Float Air Hy-Vent

Works well. Before I installed this there was some gurgling in our hot water heating system due to trapped air. Shortly after installation that all stopped. This is our second season of use with it.

This valve was an exact replacement for our old, rusted, leaking one. Installation was not too tough, but be prepared for some squirting water! It works perfectly now.

Works great on hot water systems

I just installed them. I really havent had a long use out of them but they are preforming well at this time.

Good quality. The item worked as expected.

Works fine for me, exact replacement for an old, corroded one.

Faster shipping than reported. The part was exactly what we needed

I installed the vent in a low pressure in-floor heating system that has never been without air problems, including leaky vents.. This vent was perfect from the beginning and has been over the winter. When releasing the small air bubble, there is never a water leak. Excellent value for the money.

Good product for the price point, highly recommend it

Seems to be a good Vent for my boiler and still working today !
