Water Well Problems UPDATE

Posted by john in la on December 28, 2005 at 19:19:51 from (66.157.51.184):

Thanks for the help Guys. I think we got it fixed now.

To answer some of the questions raised before......
My well is 225' deep but is considered a shallow well because the water sits in the well pipe 4' below the ground.
We hit water several times on the way down but kept digging to get to good water. (Remember I am only 10' above sea level)
I can not use a submergible pump because I have a 2" well.

Pump was loosing prime and sucking air.
Things I found.............

I was sucking straight off the 2" well casing. Was told this was normal in our area and could be done if your check valve and well casing was in good shape.

Pump was taking a long time in my mind (2 min+) to build up to 50 lbs pressure.

Took pump apart and found impeller was bad. Rather than just rebuilding pump we decided to replace the whole pump since elect motor is 25 years old. We bought a 1hp Sta-Rite.

Replaced all pipes in pump house and added a 1 1/4" drop pipe and foot valve into 2" well casing.

Run new pump with out hooking up tank and it pumps water as fast as pump will run. Shoots water 5' out of a 1" pipe. Pumping over 20 gals a min under no pressure so water quantity is there.

Checked tank and it is holding precharge air pressure so we used old tank again.

While I may have had a leak on the suction side I feel not because my check valve was holding. You could hear air running in well pipe as water was released when I took check valve off. It also had water sitting on top of it when taken apart.
I feel the pump impeller was my major problem and I just did not want to look at it because of the cost of repair. Trying to rule out all other things first.
I also feel the drop pipe I have added and raising the pump above the check valve will help prolong the life of my new pump.
Here
is a drawing of how I have the pump/well set up now.

So now $400 later we have all new in the pump house except the tank.
Now all I need to do is to rebuild the 4'x4' pump house. I decided to evicted all the mice; ants; and termites from there 25 year old house while I was at it.

Happy New Year
John
