Help on Little Giant
Hi:
My Little Giant 4MDQ-SC die on me this morning,luckly I have another Little Giant 4MDQ-SC. My question is that I can still hear the pump humming but no water coming out. What would be the problem, is it worth fixing it? I think I need to sendit back to U.S. Thanks |
Have you cleaned it lately?
|
Cleaning would be a good thing to do, if you have not done it in a while.
The Impeller can become coated with a calcium carbonate coating which can cause seizing or slowdown of the pump. You dont hear of little giants now working very often! :wink: Tough pump |
Where are you located? Little Giant has authorized service depots in several cities. There may be one in your area. Worth looking into...
PS. But, before sending it anywhere or taking it to a service rep, I'd open it and see if there is the calcium buildup (as has been suggested) around the impeller. Good possibility that's what it is. |
I had the same thing happen to me with a little giant 3md last year. take the impeller cover off and see if you can turn the motor shaft, if it turns with a lot of resistance then one of the bearings is probably beginning to seize. In my case it was because one of th oil holes on top became plugged with lint etc. I cleaned the hole with a piece of wire and added about 10 drops of oil. I guess I managed to get to it in time because after a couple of turns of the shaft with my hand the bearing worked itself loose and the pump still continues to run to this day. Of course make sure the impeller and cover are cleaned of any calcium deposits

Thanks for all the help!
I did open the cover and clean the impeller this morning. What I found is if I try to turn the impeller it will start spinning. May be Bryan is right, I will try to put oil the pump and see whether I can fix it. Delphinus: I like your signature. Actually I didnot flood my basement, I flood my living room. Fortunely, I changed to hardwoodf floor when I installed the tank. Still, take me more than 4 hours to clean up the mess. I can still smell salt water in my living room now. Ken |

Sounds like the bearing, mine did exactly the same thing. Don't be afraid to add a lot of oil and spin the motor at the same time.

I have had my pump seize 3 times in the past year. I then take it all apart and clean the oil holes with WD40, eventualy, this works. I let is sit and dry, then add oil. I'm sure I have a bad bearing!! There is a rep in Surrey, and they stock the motors. I called them the first time in a panic, I'm not sure of the price. I still have not decided if I should keep it or get something better and quiet!! I'm not impressed with this pump.

Hi:
I have 3 little giant, I only have problem with one of them,the rest run with no problem. I have no idea what cause the problem, I oil them regularly. Anyway I brought 2 mak-4 from Jayson. Very nice pump, just a little bit noisy than the little giant. |
