for winter setting drain down
some Eriba folk
fitted a switch to disable pump while taps left open.
other eriba folk have fitted a relay to save the micro switch from wearing out
if your pumps running without turning tap on, it may be the switch in tap at fault, to temporary stop the pump the 2 wires go up to the tap our are connected to the tap wires by a block connector, one of the wires hopefully the negative (tape the end just incase) could be disconnected while you seek a repair or fit a isolation switch
taps can be purchased from eriba dealers and leisure shop direct
eriba folk use a screw driver to gently turn the propeller to get the pump working after being stood over winter, if that's the fault..
more details required to give better help
