Is the pump run-dry safe? or auto shut-off if loss of suction?

I am not sure if it is run dry safe it does have a breaker that turns it off when the intake is plugged at least it has for me

If you don't have any vacuum leaks, the pump shuts off at about 16 inches of Vacuum and holds till it needs to pull back down.

It hasn't happened to me, but I would guess that the pump will continue to run "dry". Probably not a big deal for short periods of time, but could accelerate the wear on the pump.

No auto shutoff. Unit needs to be kept almost full before pump starts to suck air. I have 2 to solve problem of long hair cats getting neck fur soaked. I tried other brands and non had an auto off feature. That being said, this unit is high quality and easy to clean compared to plastic models

Not necessarily, but the pump does draw a substantial amount of current, so you should not run it for very long without the car on. I'd recommend having the car running if possible/safe, but again, it doesn't HAVE to be on. -James

I am under the impression that you should not run it dry. I unplug mine as soon as it "sputters" when emptying a water canister.

Mine only ran for about 2 hours before it ran out of water. No auto shut off

No it is not a bad sign you will have smoke/steam come for the vent on this pump. Not a concern at all just when you turn the device off make sure your still holding a negative pressure.

If I understand your question, you're asking if this pump shuts off automatically when the water level drops and it starts sucking air. The answer is no, it runs as long as you are providing power to it. Pull the plug, and it quits.

No, it is either on and pumping or off when power is disconnected. Unless you have a way to turn the power on and off from water level then it is on all the time.

Turn off the pump when you go out of town just in case. I left mine for 3 days (it's a dry climate here) and the water got too low so the pump burned out and had to be replaced.

Do u mean pump shuts down like no electric or water not moving? Water stops mean air in system open valves one at a time and burp the pump. Remove air

Yes the machine will automatically shut off, then start again when needed. Set the desired humidity level, fan speed, etc. and forget it... Well make sure the drain hose is attached and to a continuous drain otherwise you'll have to empty the bucket provided.

I personally do not leave the pump on when not in use. Grey water flowing by gravity should go thru, but if there is any debris, it may stick in the pump.

Mine does not have auto shutoff and so keep running when dry. Doesn't seem to be problematic though. Love this little beauty!

I use the pump dry. It then uses the fluid in the car's reservoir. You have to take off the pump and refill the reservoir when it's low. Look at how much you have drained to gauge when. A lot more pumping, but a lot less mess. For anything but a complete flush it is easier dry, even with the flush I would do it dry to keep the pump clean.

No. Liquid flowing through the pump "lube" it. Per the manufacturer, you should not run the pump dry.Very nice pump for home brew.
