Abstract
A system for quickly removing and installing check valve parts without disturbing system piping attached to a pump. The system includes a first adapter attached to the outlet of the pump head. The first adapter includes a valve seat and a housing with a side wall having external threads. A second adapter includes a hollow body with a space for a check valve. The body has an opening in the side wall for inserting the check valve. The second adapter fits over the first adapter and the adapters are attached by means of a collar. Tightening the collar onto the threads on the first adapter causes the check valve to be held firmly between the valve seat and the top wall of the second adapter.
