I also had to replace the pump several times. So far this one has lasted about 10 months. We seldom dry camp, but use the pump when traveling for bath room etc. When they work they are great, but when they act up your about ot of business. I try not to let mine sit to long before I have it run for awhile. Dont know if this has anything to do with it, but going strong for 10 months so will keep up with letting it run for a few min every once in awhile. Good luck with yours and let us know how you make out.
