Multiple switches for water pump

Our motorhome absolutely needs two water pump switches - which it came with from Winnebago.

One is in the usual spot right on the power control center along with other functions on the panel.

The other switch is way in the back of the RV outside it and within the storage bay where the outside shower head and hose are. Since we keep the power control center water pump switch OFF a lot to help prevent a broken internal water line from ever flooding the RV along with draining all our fresh water - we of course need this outside shower water pump switch to prevent having to walk inside back to the control panel to turn ON the water pump for outside shower usage. Also if the inside switch ever fails, we have a back up switch to be able to still use the water pump without having to do field repairs right away.

Good. Have been trying to figure out how to use the shower without running to kitchen and back after I've opened the faucet. Pump switch is in the kitchen and there is no pressure switch in my pump. The pump manual says not to run it against closed faucet. Don't want to add a pressure switch either - it's scary when it suddenly comes on like a thunder.

What pump do you have? I haven't seen an RV water pump that didn't utilize a built-in pressure switch to regulate the on/off cycling of the pump.

I'll second this recommendation. Looks like the 10 amp version can be had for 50 bucks. I didn't see a price for the 15 amp version. You can do the job with a generic latching relay, maybe for less money. This device is just an electronic latching relay. My rig has one, with 3 switches, and so far it has worked flawlessly.

I'm surprised the pump doesn't have a built in pressure switch.

I have thought of doing something similar but I have never been able to get the front panel off the range hood. Is there some secret to this or am I just not prying it off hard enough? I'm always afraid I will break it.:h

I think I was able to find where the tabs were and carefully poke a screwdriver in above them so I didn't have to pull too hard. I don't remember where they are.

Thanks for the info, I'll try to find them.

If you zoom in on my picture showing the panel, you can see little bumps along the edge. Prying in the right spots should work.

You can parallel as many switches as you want. The only problem is you will have to cut OFF the one you used to initially cut it ON with.
I see no advantage to multiple switches.

I think Horizon170 needs to read up on latching relays.
It can be done.

I suggest anyone who has never herd of a latching relay open RL57201's link. It shows how it's wired to multiple switches on the 2nd page.
