Quick update

Last Sat night I meant to top up the ATO tank, but a box of beer got the better of me
I went into my office (sump room) Sun morning to do something and the flashing LED was there to remind me of the low level

Gotta like it

I have to tell you that I have had some really bad luck with diaphragm valves. But if you are running RO/DI water through it you should have no problems. But I ran water to be disposed of, and I kept ketting crap growing in the valve and sticking it open!
