I got mine from pure freedom. Your need a tranformer (maplins)

Maccess near me (Southampton) has the power inverters (12v to 240v) for £12!  Bargain!

Hi
I 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: 051040000
The 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.

I am wanting to set up twin 4040's with 8 ibc tanks using a booster pump to fill then shut the lot off, would this work for the shut off and pump also ?

Hi
I imagine there would be no problem with this. (I presume that the tanks would all be on the same level and would be linked together.)  I am not an electrician but would operate the booster pumps through the float switch as well. Use a junction box for this. It will probably need to be wired to a seperate 13amp socket used exclusively for your booster pump.  I can't remember offhand but I think the float switch was rated at 10amp so you will need to know the specs of the booster pump you are using. I phoned Machine Marts technical help line and they gave me the info I needed about it. ie the 3 wires. The solenoid uses only a small amount of current, but the coil does get warm.

My float switch is fitted through the top of my tank. The float valve is held submersed by a short length of 20mm plastic electrical conduit and the cable gripped with a cable gland. There needs to be enough cable extending passed the end of the plastic tube to allow the flow switch to 'swivel'.
