Water Pump Questtion
I have a new 2013 23B and my wife said she ran out of water and the pump kept running for about 15 or 20 minutes. It seem to work fine for several camping trips. When I went to winterize and put clear tube in anti freez it seem like the pump had trouble sucking the anti freeze out of the jug. Did the pump get damaged by running dry? Thanks

No 1st hand experience here, but all methods and instructions say not to leave pump running empty for more than like 30 seconds during certain procedures. I can see where running it dry for 20-30 minutes could certainly damage the pump. If it's not priming and pumping, it's obviously not working regardsless of reason. Probably will have to replace. Luckily not too expensive and can be done with little mechanical complications. Kind regards, Doug

I hope your pump is ok. In order to suck the anti-freeze out of the jug, you must ensure that the valve on the tube to the jug is open and that the valve to the fresh water tank is closed. If this isn't the case, the pump won't suck from the anti-freeze jug.

I have mistakenly left the pump running with no water supply for much longer than you did, and didn't have any problems with it.
Try pouring some antifreeze into the tube and hold it higher than the pump (gravity feed the pump). If it pumps it through you can eliminate a pump problem. If the pump works, you might have an air leak on the suction side.

Sureflow pump Dry running
Twice we ran out of water while my kids were showering and they never told me until hours later and the pump continued run and work after we added water. I got onto them, about how it will ruin the pump. I then looked up the pump on the internet to see how much it might cost me someday and it states that the pump can be run dry.
SUREFLOW 4008-101-E65 The 4008 Revolution fresh water automatic demand pump is super quiet, thermally protected and can run dry without damage.

Due to an "OPPS" I left one of my pumps running (dry) all night... that was a year ago... it is still pumping fine... I do not recommend doing that.. but I doubt you have hurt the pump.

They are basically a diaphragm pump with several chambers so they won't be damaged running dry like a centrifugal pump with a mechanical seal would. Probably an air leak on the suction side as others have stated.
