Disassemble Outlet Check Valve Assembly
Not all systems will have this outlet check valve assembly installed;
some systems will have the outlet fitting or the relief valve adapter.
1. Unscrew the retainer (4101-17-1) with a hex wrench while the retainer side of the check
valve is facing upward.
2. Remove the spring (4101-16-1) and S.S. ball (9201-1-7) from the check valve and
inspect them. Clean or replace the spring or ball if necessary.
NOTE: The two O-Rings on the check valve will need to be replaced during reassembly.
