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

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

Perfect replacement

Exact replacement

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

Replaced my Maid-O-Mist, that came with my house. It was old and crusty, and I would have to press the schrader valve to let the air out periodically. I havent heard any gurgling at all this fall from the pipes. I almost want to introduce air to the system to see what happens. So far so quiet...

works great

good product

I installed this at the junction point of the feed manifold from my boiler to all the zones in my house, a direct replacement of a failed automatic bleed valve. This Taco 400-4 works like a charm. Upon refilling of the system, it immediately started hissing, which is good. Overall it took about 20 minutes to purge all the air out of the system. Very impressed. The material, construction and heft of this Taco 400-4 is quite good.

Worked perfectly. Easy to install and no issues at all.

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