RO Unit storage tank upgrade?

[digi]

Hey all,

I've bought myself a kenmore RO filter system about a year ago, and was using it for my 9 gallon nano system. It works great, but I've now sold off the nano tank and am thinking of going much bigger... probably around the 90 gallon area.

I'm wondering if the storage tank from my RO unit can be upgraded? Its only got a 4 gallon tank right now, which could be difficult to work with for a 90 gallon tank.

A link to the product I've got is here: http://www.sears.com/shc/s/p_10153_1...2&blockType=G2

Any ideas anyone?? Has anyone done this?

Get yourself a large rubbermaid or other container and install a mechanical float valve in it and simply hock it up to your RO unit.

I don't understand how this would help... there's no electrical plug-in for my current RO system. Therefore I can not turn it off or on with a float switch.

The float switch only turns off the physical pressure of water going into the tub through the hose. It is a mechanical shut off.

Something like this, no power needed.

Crazy! I was under the impression that the tank was pressurized... was about 90% certain.

This setup with the float switch shown - Is this the case for most RO tanks?
