The prototype was successfully deployed, and just in time too, as you can see the well was flooded again when I arrived. The setup is very make-shift, but only needs to work for 2-months. I’ll continue to work on a more polished design for next summer.

There were a couple integration headaches to deal with, mainly finding couplers to connect the hose to the ½’’ pipe threading on my solenoid. Even with the couplers, the hose was fairly leaky so I’m a bit worried about water getting into my enclosure. Luckily I had some marine sealant/epoxy.

For the next (non-prototype) version I think I’ll try to mount the PCB directly to the solenoid and place a gasket against its side to seal it off. I’ll also need to find a better way to set the float switch’s position. I’m designing a PCB on the side here, so once I’m about to order I’ll post an update. I expect it’ll take awhile though, especially since I have to do some 3D modelling.
