Our sump died yesterday so we replaced it with a Ridgid SP-500. 1/2 HP. (Old one was a Sears 1/3 HP).
Supposed to handle 4,400 GPH.
However, it took FOREVER to empty out my 17 X 22" well. I do realize that the 4,400 gph number varies with the height, etc. it has to discharge but this is WAY off.
We stood there and watched the water go down. I pretty much expected the water to vanish relatively instantly. Like a minute. Nope! Slow as molasses.
We made sure the check valve was working ok.
We did put the pump in for a while before we foolishly taped up the little hole in the tube. (Yes, I'm going down there now to untape it - we now know the hole is SUPPOSED to be there ) But it was still slow prior to the hole plugging.
I went over to the sump site trouble-shooting section and read something about lifting the pump above the water and resubmerging to "retrap air in control skirt". I re-read the sump booklet and the description seemed to say to put the pump in the well - then add water to test. We lowered the pump in the well (yes it is straight) THEN turned plugged in/turned on the pump.
1. The "air bleed hole" is perhaps 1.5ish feet above the point where the hose attaches to the Check valve. The check valve is attached directly to the pump (as it was in our old system). Does this sound proper?
2. Does it sound like the problem could be not having 'air in the control skirt' as mentioned above?
3. Does anyone have any other ideas as to why this thing is pumping out SO very slow?
Thank you everyone!!!
