It only runs constantly when it is not producing water. You are right that it is built to run only until it builds up pressure, then stop. And that is the way it works when it works! My problem is that if I do not use it for a week or more because I have city water, it won't prime. I have sent an email to the customer service rep at Shur-Flo asking about how long it should have to run before it starts producing water if I have not used it for a period of time. I was told by one mechanic I had burned the motor up by letting it run for too long without producing water. Well, I would not have to let it run if it DID what it is supposed to do!!
My first pump started out working fine and would produce water after only a couple of minutes, but pretty soon it took 5 and then 10 and finally half an hour of running to get started. Once it got started, it worked fine, but I got really tired of all the waiting. And when I replaced it, I had left it on an hour-and-a-half before I got water, which is ridiculous! I was told various things by various mechanics: 1) it must have a leak in the diaphragm, 2) it was my fault for burning out the motor, 3) these pumps fail all the time, etc. I have done the opening and closing taps to reduce trapped air and that does not work either.
I always make sure I have enough fresh water in my tank. (Had a mechanic accuse me of burning the motor up because I had let my tanks go dry. Mechanics seem to have a repertoire of excuses, don't they, for blaming women. ) I mainly use it when I drive between campgrounds or when I get to a campground without city water hookups. The thing is when you need it, you REALLY need it. Because it is so unreliable, I have gotten into the habit of taking jugs of water with me for toilet flushing on the road, and avoiding dry camping, neither of which I want to do.
And my cousin has had his motorhome for 14 years and has been full-timing for 10 years on the same water pump, so I do not understand this. My RV is three years old, and this is the third pump. The Shur-Flo guy has been very helpful. He even sent me some free most-commonly-replaced spare parts and told me to save the old pump if I had to replace it again, so I could put new parts in it and/or send it to them for inspection.
Next time I go to the Fleetwood factory service, I am going to ask them to reroute the plumbing and pump so I can more easily reach it. Even one foot closer would help. Then I could take the three screws out the rep told me about and replace the innards myself!! As you discovered, Velda, it is not that difficult. I think it is smart to have an extra one with you. Oh, and mine is in a dry bay, not the wet one. I think it makes sense to have it in a place where if it sprung a leak, it would not get everything wet. I store stuff in there, but ONLY in plastic bins because I am afraid of leaks.
No, I don't have a washer. Used the next-door campground washer and dryer.
So, seriously, how long do you ladies have to run your water pump before it starts pumping out water the first time you use it after several weeks? I would really like to know. And what brand is yours?
