It is recommended that any devices installed which could create a closed system have a by-pass andtor the system have an expan- sion tank to relieve the pressure built by thermal expansion.

Thermal expansion tanks are available from Sears stores and through the Sears Service Centers° Contact the local plumbing inspector, water supplier and/or the Sears Service Center for assistance in controlling these situations.
