I have a display in the bathroom and one in the wet bay.  Both are not too far from water pump switches.  One wire from a momentary switch on the SeeLevel panel to a ground line on the switched side of a water pump switch is all it needs.

Don't you also have to include a +12VDC at the switch if you want to have the LED indicator to show the status of the pump?
Don

Well yes if you want an indicator light.  That +12v comes from the latching relay as does the power to the pump.

This diagram is for the fill valve but it is the same as the water pump.

I definitely want the indicator light... our humble U270 only came with one water pump switch in the kitchen. I want to add one to the bathroom, and one by the exit door. Now I need to figure out if our coach has the wires already present in the bathroom, as I know the harness is the same in many respects across the model range. That would make a bathroom water pump switch an easy install if the wires are there. I figure I will have to run a pair of wires to the front for the extra switch by the exit. Thanks for the info!

Don, add this little programmable timer to the circuit.  Plus 12v starts the timer, when it goes off it closes a path to ground (just like pushing the pump switch again) and the power to the pump and the indicator light and the timer goes off.  Very simple add on and we never worry about "did we leave the pump on?".

I have thought about putting in your timer idea, but how do you keep the ice maker happy with it?

Unfortunately my coach has had the water pump upgrade and no accumulator. From what I have read on the Forum, it is not recommended to add the accumulator to my pump. Sometimes there is a negative trade off to an upgrade.

I did the water pump upgrade long ago and have one of the variable speed water pumps that say not to use an accumulator. I bought a nice stainless steel Shurflo 3400 series accumulator which I plan to install behind the bottom drawer in the kitchen. I did some research and found accounts of those who used accumulator tanks with the variable speed pumps without issue. I will have to do some testing, but my theory is that the cut in pressure of the pump just needs to be in the right psi with the accumulator tanks air. Some testing will be necessary to get it right, but that is my theory and I am sticking to it until I get empirical data to prove or disprove it. I tend to forget the details of past research until a project is underway, but that project is on on hold until higher priorities are dealt with... I will of course post the results when I have managed to complete the project. Worst case scenario, I will change out the pump and keep the accumulator if I find they won't play well together. The reason I am dead set on having an accumulator tank in the system is that although the Aquajet 55 ARV pump has worked well and reliably since I installed it 5 or so years ago, but having the pump run every time you flush the toilet at night or have run periodically when make RO drinking water is less than optimal. My hope is that the 2 gallon tank (total volume, .7 gal liquid at 20PSI) will even out the night time flushes and reduce the frequency of the RO driven cycles.

I tried it both ways. Yes, the pump doesn't run every OTHER time you flush, but when it does run, it runs a long time before it shuts off. That in itself was ignoring in the middle of the night.
I tried all kinds of pressure setting's on the new Accumulator tank.
The new Surflo's, make as much or more then city pressure, mine is at 55. Love it, and the wife never complains anymore about pressure when on the pump
