what happens when a return pump runs dry? Does it have an auto shutoff to prevent the motor from catching fire?
FWIW....I have an Eheim and just curious.

It can mess up the impellers on mag drive pumps if they are run dry. I doubt an Eheim will really overheat since it can be mounted externally so it doesn't need water to carry the heat away (although I guess it could if the impeller causes enough friction banging around inside the pump).

Good to know. Thanks.
Obviously, I have no intention of running it dry, but it's comforting to know.....just in case.

I understand the worries first hand! Im triple checking everything from now on! Just be sure if you smell something faint that smells like burning plastic find where its coming from ASAP! Ive been reading up on some well pump switches that work like a float switch that will cut off the pump if the water level goes down to far.

You talking about a float switch? I don't know of one that goes inside a well. I do have a float switch hooked up to my aquacontroller that will shut off my main pump if the water level drops too low.
Speaking of things to shut off well pumps, the cool thing now is a pumptec box that senses the drop in amps when a pump sucks some air and it shuts the pump off for a set amount of time. Even better, the pump I have in my well is a variable speed pump and the control box will sense when the pump sucks air and it will shut it off for a certain amount of time depending on how long it ran before. Sorry, talking about work again.
