Thanks for the write up! I’m currently working on rewiring my valve boxes with some terminal blocks from Lowe’s. I made jumpers from some of my leftover thermostat wire (18 gauge) to connect each of the sections together on the terminal block.
I’ve got:
- COM from Rachio in to terminal block
- Each solenoid COM wire is wired to the next open spot on the terminal block
- Last jumpered section on terminal block is wired to COM wire travelling to next valve box
I might go back and have the in/out COM be the first two spots on the block, just in case there’s ever an issue with the jumpers down the line, but it is working so far, for the first 3 valves that I completed last night. And the screw terminals seem to hold the wires very well.
If it develops moisture related issues in the future, I’ll look into making a waterproof box for it, or look for some kind of marine-type terminal block. But this looks like it might work great for this season at the very least.
