I just get excited , my DIY "project" :)
Hope this would help someone .
And a Big Thank You to everyone who had helped me (you know who you are :) )

The cost :

2- Float valve on Ebay $5 + $3 for shipping = 8
3- 1/4 Fitting ( John Guest Fittings) $3 at Lowes or HD
4- 1/4 tubing , 2 feet long, free
5 - piece of acrylic , free
6- bracket, glue on side to the sump

It is an excellent start. Might I suggest a 2nd shut off valve? As with all mechanical valves, it will fail. Ask yourself what the consequences will be if the top off completely drains into your sump.

Hi RocketSurgeon
Good to hear from the DIY-Pro ! Are you building ..rocket in your backyard now :)
So, place the second shut off valve about 1" or so above the first one ?! What kind of shut off valves are most reliable? Thanks.

In theory, you are correct, similar to this picture:

I'm not sure there is an easy way in your particular setup. I would have to do more investigating. Maybe someone else will chime in.

There have been many posts where the entire reservoir was dumped into the sump. Typically, if it is only RO/DI, it would cause a swing in salinity. If you have Kalk added to it, things can get real complicated real quick.
