5.9. By-passing
A bypass valve system should be installed on all water conditioning systems. Bypass valves isolate the
softener from the water system and allow unconditioned water to be used. Service or routine
maintenance procedures may also require that the system is bypassed.
Caution
Do not solder pipes with lead-based solder.
Caution
Do not use tools to tighten plastic fittings. Over time, stress may break the connections.
Caution
Do not use petroleum grease on gaskets when connecting bypass plumbing. Use only 100%
silicone grease products when installing any plastic valve. Non-silicone grease may cause
plastic components to fail over time.
