Check Valves
Inlet Check Valve
The inlet check valve is a bought-in item, and is not readily user-serviceable. To remove:
1. Disconnect nylon tubing from connector (9), by pressing in the collar at the top of the
connector, and gently pulling on the tubing.
2. Unscrew and remove connector.
3. Remove check valve assembly (8).
4. When replacing the check valve assembly, take care to remove all traces of PTFE or
Teflon sealing tape on the mating threads of elbow (7). New tape (or similar sealing
method) must be applied to ensure a pressure-tight joint.
5. Reassembly is the reverse of removal.
Outlet Check Valve
1. Remove screws (7) and pump check flange (6), taking care not to drop the check
valve bullet (3) and spring (4).
2. Inspect the parts for cleanliness and damage—particularly the sealing surfaces.
3. When removing O-rings, take care not to use any tool that may have a sharp edge that
will scratch the surfaces of the mating groove, otherwise it may leak when
reassembled.
4. Reassembly is the reverse of removal, but care mast be taken to ensure that the spring
and bullet are seated correctly.
