Auto Top Off via RO line?

[Delphinus]

I just use a furnace humidifier float valve, costs around $10-12 at HomeDepot/Rona/etc. Just the black plastic one.

I keep my bucket on a stand that's just a tiny bit higher than the sump. Gravity does the rest.

Reviving an old thread....how do you plumb that set-up? Have any pictures?

Here are some pics of mine, its pretty simple. I have the RO reservoir up on a small table so I can gravity feed the sump and not have to use a pump.



I just use a rubbermaid tub, it holds about 10-12 gallons and the john guest fitting is an inch or so above the bottom.



I just drilled a hole in the rubbermaid with a drill. I made the hole a bit smaller than the JG fitting so it would be a nice snug fit and then siliconed around it:



A friend built a bracket for me so that I wouldn't have to drill the sump and it works nicely.





I have the level set up so that if the power goes out and the tank empties somewhat and the skimmer as well, the sump won't overflow.

Hope that helps

That would be great to see!

Thanks for the pics! I picked up a float valve like Mark's at Home Depot today, but I was not sure how to put everything together until Christy posted her setup.
