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

Excellent quality, same as original on my furnace. Very good price. Be very careful when rplacing yourself, make sure water pressure is released & no HOT water in furnace or you will get burned.

Taco 400-4 1/8-Inch-NPT Float Air Hy-Vent. This Taco unit works! I have used this Air Vent for at least 10 years and I am a satisfied customer.

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.

My home hot water heating system is 25 years old and the air vents green, crusty and plugged up solid. These Taco easily screwed right in and are working well.

Yup works just like the last one I changed

Worked well

works as it should. Had to change ex tank and auto fill valve and in a short time air was out of system

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

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

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