OK, first of all I'm not a DIY person so please bear with me. I have a fairly new Grundfos MQ. It pumps water from my storage cistern (that receives water from the city) to a larger concrete tank I use for gardening, via a crossfeed valve. I left the valve open today and totally forgot about it. It pumps water out faster than what comes in from the city, so when the water level got down to the level of the intake, it began gurgling and pumping a mix of air and water. At this point it was pumping exactly the same rate as what was coming into the cistern (because some of it was air) so I don't know how long it was running this way. I would estimate one hour. It was not hot to the touch and it reprimed itself and seems to be running OK so far.

So my question is: should I have this pump inspected by a technician to check for damage? This pump is critical for both household and garden, so I don't want it failing on me.
