Cheap flood insurance

[avanti]

I just came across this interesting device:

https://www.amazon.com/UCTRONICS-Tac...3PKKZCDN9HCH1K

It is a little timer board that can be configured to limit the amount of time a 12VDC device will run after power is applied. It would be very easy to use it to limit the amount of time that a rig's water pump can run in a single power cycle. This would be valuable protection against pumping the whole fresh water tank onto the floor of your rig in case of a plumbing failure in an unattended unit.

I know that many people power off their pumps when leaving the rig, but even if you do so, this mod would provide a valuable and extremely inexpensive backup.

So you would put this between the pressure switch and the pump itself? Otherwise you would have to turn the pump on and off after every use, depending on the setting.

Yes.

P.S. -- Why does the list require a minimum of 10 characters in a reply?

To prevent certain "four letter" replies??

I recently used one to create a delay for the A/C initial turn on to give the generator a chance to warm up. Works great. I like your idea for the water pump. On our last trip a guest used our toilet while we where all sitting at the park bench. During a lull in the conversation I heard the water pump running. Toilet paper had stopped the flush valve from closeing completely. What a mess! Must order another module.

Great idea Avanti.

A family in a Class A pulled into an overnight spot (hotel parking lot) next to us that only had electric hookups for RV's, no water & no sewer. They had started the trip with plenty of fresh water. Something in the bathroom fell - I think it was the shower head - anyway, whatever fell hit a tap and turned it on. They had left the pump switch on so when they got to the overnight spot there was no fresh water left in their tank.

That timer board would have saved the day!

Pretty low tech and not nearly as good as a passive safety device, but I changed our water pump switch for a lighted one. We have made it a habit to glace at the switch whenever we hit the road or leave our van.

If it's glowing red, it's rock/paper/scissors to see who has to step to the back to turn it off.

I have my water pump always on and never had a problem, lets cross fingers. I lost all water when a loose shoe kicked by a semitruck hit and broke my strainer on the highway. I use this strainer to drain water from fresh water system so located it in an easily accessible place but unfortunately it is vulnerable. Since this episode I carry a spare plastic strainer cover.

I think having a timer to shut off the pump would be great additional protection for flooding and the pump life is a very good idea. I am not sure how easily accessible is wiring from the integrated into the pump a pressure switch, but will add it to my to do list.

We have pretty much trained ourselves to turn the water pump off if we leave the van. They are just ingrained in us now in other things like not leaving our keys in the van.
