Can we set up 2 water pumps such that they never run simultaneously?
There are something called &quot;alternating relays&quot; or &quot;alternating switches&quot;, not to be confused with alternators for cars/trucks. The good thing is they aren't a &quot;one off&quot; configuration, they are industry standard. The community water system I helped support used one to alternate between 2 pumps. Worked great.
