Hello everyone, I have a new to me 04 Alpenlite Aspen 28RK, and I'm a little worried about the way the water pump runs.
First and foremost, this is not the original water pump, as the manufacture date is 2010. Pump is a Shurflo 2208-422-444, 2.8 gpm 45 psi. It doesn't matter which faucet I'm using, the pump cycles on and off about every 2-3 seconds, creating a surge-fade cycle. My concern is this will wear the pump out early, and I almost exclusively boondock, so I need the pump to last. Aside from removing aerators at the faucets and boring out the shower wand, what can I do to stop the cycling and get smooth water pressure? My old 91 Wilderness 24C didn't have this issue with any faucets so I'm at a loss here. Is my only option an accumulator, or the aforementioned "modifications" the only options?

The answer is that you have a leak in your water system someplace at or after the pump. The pump is trying to build pressure but it can't because the pressure is leaking out someplace. Start ar the pump and make sure all fittings are tight and keep an eye open for wet spots.

If I understand correctly, this surging happens while you are using water, and not when the faucets are turned off. There should be a pressure adjustment allen screw on the pressure switch. Turning clockwise will increase the pressure at which the pump will turn off.

There are a few videos on YouTube.
I recently bought a new pump and had to adjust it.

No that would be cycling when I'm not using a faucet, that I'm aware of and all lines and systems have been leak checked.

Thank you, I'll search them up and get an idea before I go back to the trailer.

Check out "attenuators" they use a compressed air pocket to smooth out the pressure. It can also provide a short time of pressure for those late night trips.
You splice it in line after the pump.

This is the accumulator I mentioned, and might be another option. I'll try adjusting first, then use this if needed.
