Water switch

The Camp Inn has a switch that powers the water system. The folks at CI installed a water system in my friend Lori's TD. I was going to ask Craig about it last weekend but was distracted and never did ask him so I will here.

The switch needs to be powered on to operate the pump, it then must be turned off when not in use so that it will not keep pressurizing the tank. Maybe some have heard the sound, a little buzz as it maintains the pressure. It obviously draws power to keep the pressure up. Here is the question: Is there a switch that will automatically turn itself off after a reasonable delay in use so as not to use up the battery when I forget to turn it off?

Jim,

No. Actually, one could make one, but you don't want to go there. The pump does not pressurize the tank, just the delivery system like a fuel pump in a car. If the pump turns on by itself there is an open valve or a leak in pressure - maybe back through the pump.

The battery doesn't care much. If you don't have any leaks, consider the little buzz as a reminder to turn the switch off.

Unless your tank is empty and the pump can't build up pressure, it won't run for more then about a half second - unless you have a leak, like Hildtich said.

With the switch on all day, the pump might run for about 10 seconds extra that day. I can't imagine that the LED is using much power either.

All that being said, I actually like the idea - one less thing to have to remember to turn off.

 

If you leave the switch on wont it burn out the pump.??

 

The water pump switch has never been burned out in the 5th wheel owned as a married couple.

 

The pump is a pressure pump and does not run unless it's internal pressure switch calls for it. The pump will not run as long as the water line are pressurized. When you open the faucet it relieves the pressure and turns the pump on. When you close the faucet it turns off again.

The lit switch for the pump is so you can kill power to the pump when it is not in use. We have found that the pressure will relax in the lines enough to briefly run the pump every couple of hours when left on. So, when finished with it for the day turn the power off to the pump. It has a light on it (LED now) that indicates if it is on or not.

I have a timer switch on a bathroom fan (110v), it turns the exhaust fan off ten minutes after I switch it on, is there a similar switch for 12v applications?
