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

Whats not to love about a Taco vent? They last for years. Fast delivery - direct replacement.

Yup works just like the last one I changed

Bought to replace old vent i had

works great

I was struggling with air in my baseboard heaters and kept trying to bleed the system and the noises kept coming back. Someone suggested I give this a try. I installed it, which was very easy, and the noises immediately went away. Wonderful! Couldnt be happier.

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.

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

I have really bad water (chlorine), and I go through a lot of these. They plug up and/or fail quickly, and Ive had faulty ones right out of the box. I recommend the Watts FV-4M1. The Watts work better and last much longer, theyre just hard to find and cost a few bucks more.

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.

Exact replacement
