Here is one popular pump controller:

Another alternative is adding a wireless remote to an existing switch, and using the remote at the new location. The common ones are fey fb types, though, so not sure your wife will be able to use those easily.

I would have to see the device. It probably has a simple relay output and you can supply 12 volts to on contact or ground and then output it to the water pump circuit.

If you turn the pump on with one switch, can you turn it off with the other switch?
if not, then yes, you can piggy back a switch.
If yes, then you need s 6 terminal switch which can connect to wet bay switch.
Look up How To Wire A 3way Switch with google, and then adding a 4way switch.

One switch can turn on and the other can turn off, 3 wires at each switch, 12 volt wire and 2 travelers. I checked 4 way switch wiring diagrams on Google and then attempted to find a 12 volt 4 way switch. None to be found. Based on the diagrams I'm seeing, wouldn't a DPDT switch do the same thing? Connect the middle terminals together and then run the travelers through the top and bottom terminals. Am I missing some special function of the 4 way switch that this won't accomplish?

There is another option.
I picked up a small, 2 gallon pressure tank and push fit tee from Home Depot. I cut into the cold water system under the sink in a dead space. With PEX pipe, you could put it anywhere.
I did this to cut down on pump cycling but discovered we could get 3 or 4 flushs, with out the pump running. Now we travel with the pump off.
Just be sure it is designed for potable water.

Here is another option for you.
Use one of the remote control relays that is a simple on/off. You have been given some examples in prior posts.
since you are just worried about having the pump on in certain situations, don't mess with the existing switches or wiring as it works now. Simply use the remote relay to cut the 12 volt feed to the pump when you want.
Then leave one of your existing switches turned "on" and cut the power with the remote control when you want.
This method won't turn on the pump if the other switches are set to "off"....however this isn't a problem since you will know how it works.
It is also easy to undo this modification when the time comes to trade in or sell the coach.

So, your saying that the remote relay would be installed on the positive side of the pump line after the switches. Turn the pump on with the inside switch and then the remote becomes a wireless on and off switch for the pump.
I like it.
Thanks

Yes, you can use a DPDT switch.
I think you understand how to wire it.
In your current setup, the wires you call travelers, are basically parallel wires, and only one at a time is being used.
If you went to your RV and swapped the connection of the travelers, the pump would toggle to the opposite state. With the DPDT switch, you want to cut the travelers, then use the new switch to restore the connection. When the new switch is thrown, it basically swaps the travelers.
Let me know if this makes sense, or I can draw a diagram.
Regards,
Dan

Remember, if you do this, the remote becomes a master switch. When on, the other switches work as normal, when off, other switches are useless.

Dan

Forgot to add.
To wire the DPDT switch, take 2 short wires and connect the corner terminals in a X configuration.
This lets the switch "cross" connect the travelers.
then cut one traveler and connect one end to center terminal, and the other end to a end terminal.
Repeat for other traveler.
Hope this helps.
Dan

This is going to be the easiest way to add the third switch. Granted, it will be the master switch but as long as we don't forget how we redid the wiring we should be OK. I have a remote relay on order from EBay.
