On our last trip out, our water pump seemed to go crazy when we took showers. The sound was awful, and I could actually hear the sound of PEX tubing rattling against the shell of our unit. It was a rat-a-tat-rat-atat sound.
Crazylev, i have been having the exact same problem. I used my shower for the first time today to test it out (one neighbor saw me heading out to my trailer with the towel and soap). The shower flow starts out fine, then once the pump is nearly finished with it pressure cycle, rattle-rattle. It's hard on the plumbing, and harder on the pump. Listening to the pump up front, it is rapidly 'clicking' with a relay like sound.
Here is what I done prior to today's shower to try and correct the situation.
Check and clean all filter screens on all fixtures
Check and clean filter/strainer on the vacuum side of the pump.
Make sure all air is bled out of lines and fixtures
adjust the pressure switch set screw (per manual) about 1/2 turn clockwise
Pray to any god of my choice
The manual says NOT to adjust the screw more than 1 1/2 turns. I'm 1/2 way there, assuming that it was at the neutral position before I started turning it. I'm going to give it another 3/4 of a turn to see if it fixes the problem, otherwise, I'm thinking about putting in an accumulator tank. That should take care of the problem.

"Keeping an open mind is important, but not so open that your brain falls out."
I am revisiting this thread because while camped along the Missisippee river, I went to use the shower, the same awful sound and banging re-surfaced.
We are boondocking. Using the Honda for power while cleaning (showering). Water runs for about 5 seconds and goes into vibrator mode. This time I noticed that if you open another fawcett somewhere the shake rattle and roll subsides. I don't think it's a generator thing.
I have checked the outside city water inlet and it is secured. Another thing noticed is that normally when I open a fawcett, water will run for about 2 seconds BEFORE the pump kicks in. On this trip, the moment you open the fawcett, the pump starts up, and does not turn off until fawcet is closed.
Is this air in the lines?, Would adjusting the set screw on the pump 1/2 turn solve this as mentioned by Westfalia et al?
BTW- I checked the low drain valves, front and back, and all seems OK and I don't see any (visible) leaks, or water dripping out of the trailer anywhere.
This is driving us crazy!!!! And I don't smell so good because I'm hurrying in the shower!
Help improve our air quality by helping me if you can.
Thanks.

I was wondering why my pump was running on and on then I noticed water outside the trailer. Make sure your outside water hookup is capped. If the cap isn't on tight the water will pump outside and you will see a puddle(Classic trailer). I happen to do this every once in a while, turn my pump on, it keeps running, and I know right away that the cap is off or not on tight.

The other place to check is your low water drain valves which you use when you winterize. I remember one of those not being entirely closed. A slow drip was enough to make that pump occasionaly run. Those valves are near the streetside front wheel on the tandem axle trailers. Drips from those are not easily seen.

Base---if you have water coming from your water inlet you have a problem too! Even if you leave the inlet cover off there should be no water coming back out.

Thanks folks - pump rapid cycling problem seems to be fixed. Thanks for all the wise words! I got the pump model number from the pump ( standing on my head while holding flashlight, mirror and pencil while reading numbers backward in the mirror!!!). Went to the Shurflo web site and found pdf document which described the exact problem and how to adjust the pump. Just as Xray suggested, there is a phillips head screw in the center of the end of the pump. A small clockwise turn while the water was running reduced the cycling of the motor to about 5 sec on - 2 sec off. That seems to be Shurflo's recommendation so I'll leave it at that.
Thanks again for all the help!
