text: Hank: How's it going?
  Tom: Like blood from a stone mate!
  Tom: Been struggling with the damn pump all day.
  Hank: Damn!
  Tom: Yeah and I'm still no closer to a solution.
  Hank: What's been going on with it?
  Tom: It kinda works and pumps the water out but it doesn't produce enough power to pump it out through the hose.
  Hank: Air bubbles?
  Tom: Yeah, I thought that too but I'm not so sure now.
  Hank: Have you tried throwing it into the pond and wiggling it around to see if you can dislodge the air bubbles.
  Tom: Yeah, been there done that.
  Hank: And...
  Tom: Seems to work for a moment then you put it back in the sump and we're back to square one.
  Tom: I thought of taking it apart to see if maybe the turbine needs cleaning out.
  Hank: If you can help it please don't do that as it might invalidate the warranty.
  Tom: Might need to do that because I think I've exhausted every other option.
  Hank: Wait until I come home and I'll see if I can manage to get it going.
  Tom: OK.
  Hank: I'll be home by 7pm.
target: Tom's pump doesn't work properly. It sucks the water in but pumps out just the air bubbles. Nothing helps. The pump is still on warranty. Hank will be home at 7 pm and will check the pump.
