Additional Flowswitch


Out of stock


It has been increasingly obvious that we needed a better solution for negative head situations and situations where with some shower and tap mixers the cold mains pressure cold overpowers the gravity hot.

The solution to both problems is to sell an additional flow switch which is fitted on the cold and so this can activate the hot pumps. With a SP21S on the hot the two 0.5 bar pumps on the hot will give you 0.5 plus 0.5 = 1 bar which is the equivalent of mains pressure on the hot and with mains pressure on the cold you will have a smile on your face.

The flow switch comes with 22mm to 15mm adaptors plus 2 number 3 way adaptors plus two 3 way cables to link the flow switch to your pumps on the hot.
