Pitcher pump not pumping


I've got a well point that I've driven into the ground about 5 feet. It's
got small (0.5") openings with very fine screen to keep any sand/soil out.
The pitcher pump sits on top about 30" off the floor. I've let the leather
soak and tried priming the pump but the more I operate the handle the
harder it moves. Very spongy. I leave it be for a while till (I assume)
the air returns. I take the pump off the pipe and the water level is higher
than before trying. So it is drawing the water up. But no water is pumped.
The flapper valve at the bottom of the pump seems to be ok.

Why is it not pumping? Is the water maybe not flowing thru the screens
fast enough to keep up with the vacuum the pump is pulling? It gets to
the point where I can't move the handle at all.

Oh, and just as a test I wanted to see how fast water drained in the pipe.
After 1 min. - 1.75", 2 min. - 3.75", 3 min. - 5.5", 4 min. - 6.75" and
5 min. - 8.25". These are rough numbers as I was trying to read a clock
and thread a tape measure down the pipe at the same time.

Thanks.

Re: Pitcher pump not pumping


Your assumption that the screen is not allowing water through is a good possibility. Another possibility is that there just isn't enough water available in the ground. At 5 feet deep you're probably not into a very large source. Can you remove the hand pump and try pumping with maybe a drill powered pump to see what amount of water capacity is available?

Ah, hadn't thought of that. I'll see if I have something I can rig up to try that. Thanks.

Re: Pitcher pump not pumping


Ok, tried that. Once I got another pump to actually have suction (around
maybe 2000-2500 rpm) it sucked it dry fast. Which shouldn't be too
surprising since the sucking end of the garden hose was so close. At
that rpm it was supposedly pulling 80 ft. gal. per hour. But isn't that way
more than the pitcher pump will pull?

Pull the pump and clean the screen. The spongy feel is from air pressure either + or - .

Re: Pitcher pump not pumping


There is no screen on the pump. The screens are on the point, which at the moment is
pounded 5 ft. into the ground. I figured the sponginess was from too much vacuum. Just don't know how to fix that. I had planned on pounding it in deeper but haven't got that far yet. And that may not fix it anyway.

Oh, here's a thought - are you even supposed to use a point with a pitcher pump? Or
does the pump require an open 'well' full of water?

Re: Pitcher pump not pumping


Yes it will probably work better with the hand pump in a "well" of water. Hand pumps aren't efficient enough to pull water through a tight screen. Connect your pump to a smaller diameter pipe inside your well pipe. I do think you should go deeper if you can so there is a larger reserve of water in the well pipe.

Re: Pitcher pump not pumping


Ah. The fitting on the pump is 1.25". And that's the size piping I have pounded
into the ground. Since I've put this down cellar thru a 3" hole I drilled thru the
concrete floor there's no way to get a drill rig down there. I was hoping not to
have to put it outside but I may have to now. Hmmm...

Re: Pitcher pump not pumping


A suction pump doesn't pull water up. You need a source of atmospheric pressure air down in the well to push the water up into the partial pressure created by the pump.

That's why you use a down pipe inside the casing that you drove down, and you need to have a vent to let air into the space between casing and down pipe.

You can try adapting a 3/4 pipe to your pump and pumping water from the well. It should work, but will produce less water per stoke.

You pump was made for an 1-1/4 down pipe to be inserted in a larger casing.

This video shows how you one of the typical ways to install a pitcher pump.
