I have a 40', 6" cased well, 30' of water in casing, with a 1 hp submerged pump, setting 6' off the bottom of the well, cased well is capped at top, water pipe and wiring only coming out of capped top. Problem now is I have water coming out of the wiring hole, looks like a small fountain and the pump is cycling quite often. We've had two days of rain here with the amount totaling around 6.5" with more rain coming. Does anyone know what might be causing this to happen, I've lived here for over 30 years and have never seen this happen. Any suggestions would be helpful, my Thanks in advance to anyone who replies to this post.

 

Maybe there is something wrong with your pitless adapter? You will have to maybe dig down to where the pipe to your house leaves the casing. I've never personally had any trouble with one, so I can only tell you what I have read.

 

This is fascinating. Yet unfortunate.

Does this water squirt out only when the well runs?

 

Hi all,
This phenomenon is not uncommon. Wherever you well springs are fed from are most likely overfull causing the water to act like a geyser. I personally have only seen about 2 or 3 in my life. I was told they were called true artesian wells, but am not sure if that is the real name. If it becomes an issue a small vent line may need to be piped into the well seal to release the excess pressure. I am a plumber and more of an installer of pumps not the well itself. you may want to wait for a well guy to answer this or just call your local well drilling company for further info.

 

NO it doesn't seem to make any difference if the pump is running or not. Since our water table is so high around here, about 8.5' beneath the surface, I thought it may be causing the well water to rise and bypass the pump. Seems kind of strange since my neighbor is about 100' away and is on the same underground water supply, and his set-up is almost identical to mine, but he isn't having any problems. Tomorrow, I'll take the suggestion and add a couple of vent lines to the top of my cap, might be just air pressure.

 

coffeepot,

I just ran out of my coffee, and actually wished I had more while sitting here.

Anyway, my question was asked so that I too could ask, depending on your answer, if your well went artesian-like, since it happened after all that rain. Your neighbors may be into another strata where layers of packed sandstone, shale, or whatever, makes it so they are not in the vein you are.

A county man may even be interested in your situation! There should be a dept. there in charge of all the well driller's logs/maps, as that should be required.

Keep us posted, regarding all this. This is interesting.

 

Hello, I just searched this issue because during inspection of a house I am buying, this exact thing is happening. The pump is short cycling as well but I think that is unrelated. The well casing is all in a 24" vertical pipe and has the normal adapter along with one open to the inside of the casing to allow water to flow right into the basement. There is a very large stone hearth with a pool where the artesian well fills and then overflows into an outlet pipe out the front of the house. There is also a 4" drainpipe in the 24" vertical pipe to allow excess water to drain and flow into the creek 100' down the hill or so. I'm interested to learn a lol more about these because I have never seen one and neither has the inspector or septic guy that was there!
