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

works great

Works as supposed to. Comes with literature to explain operation.

It works like it should.

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.

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

Good product for removing air from hot water heating system. Durability may be an issue as sometimes they will stick and fail to remove air. But overall it work well and doesn’t let water spray out everywhere

Works as expected and price beats local plumbing outlets

Im buying this for the second time in 5 years - to replace the original which lasted over 20 years. Same brand / same part number, but no longer made in the USA, hence the much shorter life.

Worked well

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.
