DIY Float Switch for ATO. For X'mas, my husband ordered 3 float switches (cost him a total of $8 or something). We're just now getting around to putting it together.
He took an extension cord, exposed the wires, hooked it up to the switch, sealed it, and put electric tape just as added protection, even though it was already sealed.
To give the switch a smooth water surface, we took a spare PVC pipe (4" diameter", drilled a big hole to let water in, and attached an acrylic base to help steady it. Hopefully the water inside will keep it stable that I don't have to anchor it to the side of the sump.
Then, we cut slits at the top of the PVC, slid another piece of acrylic that will hold the float switch in place.
The idea, of course, is to give the float switch a smooth water level because the water in the sump is turbulent from all the water flow.
It will be hooked up to the dosing pump, which will of course pull water from my rodi water reserve, and into the intake part of the sump.
That's the idea LOL I'm waiting for the silicone to dry & cure overnight, then I can test it. It's not the prettiest, but who cares....no one but me will see it, and it was dirt cheap! :mrgreen: Total cost, including the dose pump, probably $20-25 in parts.
A shot of it before we siliconed it together. The hole, of course, is to allow the water to enter. The slit on top is where we put in the piece of acrylic that will hold the float switch. You see the float switch on the tabletop next to it.
A view from the top...testing to make sure everything fits. See how the acrylic was slid into the slits.
Waiting for the silicone to dry at the base :) The PVC and acrylic base are the only things siliconed in. The float switch and its acrylic at the top are removable.
