long runs with monoflo tees?

d henry

i just completed sweating a 1 zone loop of five radiators. one of the radiators was a bit out of the way, so i put in two 12' foot runs, with a monoflo tee on the feed and return (1 x 3/4)

has anyone done this? will it work? or have i probably plumbed a radiator that won't get hot?

Sure using two tees is what you can do on down feeds, long runs and tough base board runs . The second tee increases the pressure drop more then one tee does . The pressure drop is what moves the btu's into the radiation. It should work with-in reason as long as the risers are not too long and that you did not leave any air traps to block the flow...

Monoflo tees...

If you have trouble eliminating the air from this setup, you may have to cut in a purge valve set on the return from the heating element and purge it out as a separate zone off of the main.
