1/4" tubes/connectors/shut off valve


General Notes

I used 1/4" water line to feed my system. My friedgerator already had a line feed to it that I just T'd off of. I then used the shut off valve to also act as a cheap regulator. I did this so the water just trickles out vs blasting out at full pressure making a mess and scaring my cat.

12v power supply brick to run to relay/solenoid valve. Cut 12v wire to plug into relay. Then relay to the solenoid valve. Then Ground wire from solenoid valve back the power brick ground.
