HiI bought a 230 volt solenoid valve from http://www.airlines-pneumatics.co.uk/webcat/Detprod.asp?ProductCode=S07012210 = 1/2" Normally closed order code 106904. It doesn't need a transformer. It is mounted on the mains supply to my RO unit in the garage.I got a float switch - the same as used on submersible pumps to operate the solenoid valve in the IBC tank from Machine Mart.http://www.machinemart.co.uk/shop/search/filter/float%20switch/type/any/page/6 item at bottom of page product: 051040000The float switch has 3 wires so can be connected to switch the power supply off when the tank is full. (opposite to the operation needed with a submersible pump)I find the float switch is ideal as the IBC tank needs to be emptied by about 300 litres before it kicks the solenoid valve on so the Ro is being operated for long periods of time so works more efficiently than a stop / start microswitch would IMO.Spruce
