Control city water supply with 12v water valve

afidel, Thanks for the information about the psi of 12v solenoid valves. My thought is to locate the valve in the wet bay. Even though when shut off there will be pressure to the valve so if there is a failure/leak at the valve or water supply to the valve, the water will run out of the electrical and sewer service holes in the bottom of the wet bay compartment and cause no damage. In the wet bay the valve will be out of the weather elements.
