Hey guys,
Recently got my 4040 to system and it works great without a pump.
What parts do I need to make it turn off when my static tank is full, I've seen a lot on pure freedom, but was hoping to source parts and make my own.
Cheers, Gary

Honestly, just buy the kit from PF. You then assured of the right solenoid valve, ie normally closed.
12 years ago I made my own up using a float switch
https://www.machinemart.co.uk/p/float-switch-230v-2m-cable/
and a 230v normally off solenoid valve.
(I can't remember where I bought the solenoid valve from. It was much more expensive than the PF kit. I heard of someone who used a cheap solenoid valve out of an automatic washing machine.)
I supported the float switch on a length of 300 conduit with a connector on each end to pivot the cable on one end and secure the conduit to the roof of the IBC tank.
This allows me to take around 200 - 300 liters of water from the IBC tank before the r/o kicks in.
Its lasted 12 years but honestly, it wasn't worth the chew.
Secondly, I'm told that even although the float switch is the same as is used on a 230v submersible pump, my contraption doesn't fit in with electrical safety standards using 230v under water. This is why manufacturers and suppliers use a lower voltage solenoid valve with a transformer.
I have it covered with rcd protection.

I rigged up my own 12v one a few years ago. Still going strong. You need to be familiar with electrical diy & plumbing but if you’ve built your own static I guess you are.
I’d use a 12v normally closed solenoid similar to this: http://www.solenoid-valve.world/selection-guide/material/plastic/nylon/1175BC?gclid=Cj0KCQjw_r3nBRDxARIsAJljleG2Ym2uBLh1COwOAcqvjN4bm9Of39WoX0dlREzCRV-xjOcjQyZrAA8aAt2tEALw_wcB
and with a vertical mini float valve so you can fill the ibc to it’s max. I can’t find the one I have but it’s smaller than my thumb! Goes through the top of my ibc.
I’d also remember an overflow as mine failed once & when I entered my garage the next morning I stepped into an inch or so of water. Obviously make sure you drill above the max of your float valve once full else it’ll never switch off. Common sense really.
