Hi I've just joined this usenet group.
I would be very grateful if anybody could help me with my problem :
My current central heating system has two pumps : SMC 3 Port Pump and
an SMC 2 Port Pump,
the 3 port pump has failed, and as SMC do not make pumps anymore. Can
you suggest fitting an alternative to the 3 port, ie Grundfoss, or if
anyone knows of a supplier/stockist who still has old stock of SMC
Any help or suggestions would be greatly appreciated.
