Insert check valves.

JohnNY

Has anyone tried using a plastic insert check valve, like the ones found in cartridge pumps but sold loosely, in a valve/nipple/flange anything like that? I have to use a UPS26-150 pump which doesn't come in an "IFC" type version in a tight space where I'll have to pipe in an 1-½" check valve instead.
The 26-150 volute won't take an insert.

These are our new checks, available in all sizes and any connection.

Same Neoperl check as found with circulators, low pop, soft seal, conical "flow friendly" shape.

Unions to service easily, like when teflon tape or other crud gets inside

12 pipe diameters from a circulator discharge, ideally for a check.

Those are pretty darn, too. Thank you, Bob.
