“Used in my home to keep air from building up in heat system...just bought the house and seller just had new one put on 2 months before I bought it, other valve was less than 8 months old (no name seen on it). I bleed system a number of times would not work right, Put this Vent on has been working Great since...No air build-up in system”
“I'm 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.”
“It fit as expected and worked perfectly as part of my preventive maintenance. I could hear the air coming out of the vent after the boiler was filled with water.”
