Zone Valves

JimboJimbo Member Posts: 201
Doing new boiler system, hot water fin tube, with 2 zones valves. installing the zone valves on the supply manifold, do I need check valves between the manifold and the zone valves?

    You should not need check valves. Not flow can occur with the valves closed.
