RODI Auto Shut Off Valve

[Curren007K]

Enjoy this crudely drawn diagram of my RODI and Booster pump.

I want to install a auto shut off valve and float switch on my storage container.
Could someone verify where the valve should be installed, is this correct?

I never drew in the waste line from the membrane to the booster, but you get the idea.

Not sure I understand what you mean by shutoff do you mean this.

OR this?

The second one.

That's where I would place it, only ever used a booster pump not the RO buddy booster pump like it looks like you have so not sure how that will affect it, but the placement inline is correct. I build these as my job so I hope I'm right! Does the pump have a waste line restrictor built in or is it just missing from the diagram?

I also just remembered does the pump have a built in high pressure switch? I remember reading they have a built in low pressure switch to prevent pump damage in the event of no water but doubt they put in a high pressure switch. When I build a system with booster pumps it gets both a HPS and LPS

The booster does have a built in restrictor for the waste line.
Also it does have both high pressure and low pressure built in, does this render the autoshut off useless?
