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

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

Product was poorly packaged with no protection. Luckily the item wasn’t damaged

works good

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.

I shut the system down, ordered this part, it came in the next day, I installed it. It does what its supposed to, end of story.

1/4

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.

Direct replacement. And prime next day for the win.

still have air in my system and not sure how long it takes to help get it out.

exact replacement - works fine
