I need a valve to stop the flow of water if I have a line break.

Is there a control valve that will shut off the flow of hot water between my home boiler and the zone heating unit if there is a break in the line resulting in a drop in line pressure?

    Thank you for the information. I recently had a 1.5" Plex connector break and it almost caused my house to flood. The pumps kept pumping hot water and it as almost a disaster! I am looking to add some safety devices. Thanks again!

    I'd be wondering why a 1 1/2" PEC connector broke.

    If the fill valve to the system was turned off, it wouldn't be draining out.

    I still want to know why a 1 1/2" PEX fitting broke. Was it under torque stress? Was there not enough room for expansion?

    Its a fine idea to leave the fill valve off, as long as the boiler has a LWCO and alarm, and is piped properly to not let the boiler water all drain out. I'd be figuring out why it broke. Its highly unusual for a PEX fitting of that size to break. There had to be a contributing cause.

    IMMO.

    I've seen several safety devices designed to stop major flooding once water is senced at predetermined locations. Neptune, Flood Stop, Quisp. Not cheap, but sound interesting.

    We've been using Axiom glycol feeders whenever we put glycol in a system. Might not be a bad idea on straight water systems either?
