need to fit an automatic bypass valve on an s plan 2 valve system as one was never fitted also pump overrun was not working as who installed this never put a separate feed mains to boiler and separate live demand from the wiring centre ,pump overrun now works but bypass needs fitting asap.
all I want to know is there a minimum length of pipe work required valve will be fitted near to pump outlet and back to return on boiler which is a Worcester bosch r1 18 heat only thanks baz
