Safety: Turn off main water and relieve pressure before disassembling the bypass.

Exercise bypass: Gently move the bypass between service and bypass several times to free it. Do not force it.
Inspect for leaks: If leaks occur at the stem or body, the internal seals may be worn.
Rebuild or replace: Many Culligan bypass valves can be rebuilt with new O-rings and seals; severe cracking requires full replacement.
