Can't beat a classic
By John in Building Maintenance
from Los Angeles, CA
Used to vent the main steam and return lines in our apartment buildings. Vent capacity and reliability second to none in this class.
Works like it should
from Ann Arbor, MI
Had to replace a #76 valve that was used on a system that was originally coal. Used the #75 as the boiler is now natural-gas powered. It installed without a problem. So far there are no issues with the valve, and I am very happy with the results.
I would definetely recommend
The product worked as advertised and the price WILL BEAT ANY COMPETITOR.[...]

This is what I'm talking about
from Boston, MA
At first I thought, "Do I really need a [$] vent?"Worth every penny. These and some pipe insulation did the trick. Regular vents just don't let the air out of the system fast enough. Now I'm heating my house and not my basement. Looking forward to a toasty winter in our 4,000 sq ft 175 year old home, at last.
