Insert check valves.

JohnNYJohnNY Posts: 2,364Member
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.
