Water shut off solenoid on timer

LOL - Dont worry you are not over my head with your design. I just think its stupid and unnecessary that's all. So you traded in one potential problem for another - hitting your switch every 15 minutes. hey whatever floats your boat I guess. I'll stick with just flipping off the already built in switch like I have been doing.

Actually, I think it did go over your head, at least a little. Why would he have to hit his switch every 15 minutes? That would only be necessary if he wanted a constant non-stop flow of water all day long. And your actions of hitting the "already built in switch" is irrelevant to the OP's city water hookup.

You flip a switch (for your water pump) EVERY time you want water...then you flip that same switch AGAIN to turn it off EVERY time. Fine. But for those RVers who use City water, that's not an option; the only way to turn off the water is by going outside and turning the faucet off.

The OP's system requires only a single button press when he wants water (just like you pressing a switch), but he doesn't have to do anything to turn it back off (unlike you, who has to press your switch again to turn your pump off); his turns itself off automatically after 15 minutes. Actually pretty smart; Virtually no risk of water damage from a plumbing leak, without ever having to remember to turn anything off.

Of course, his system only works for city water, but the same idea could be adapted to the onboard system easily as well, automatically turning the water pump off after 15 minutes.
