pump line casing distance

Hi, I have a leak within the 8" pipe (where the dual PVC lines are). I dug up the outside of the foundation where the casing comes thru but it seems to not end within a few inches of the wall. How far would this normally go? Does it go all the way from the house down to the well? The pump is inside the basement. It has a steady drip inside the basement after heavy rains.

thanks

I think you are describing a conduit pipe through the cellar wall encasing your deep well jet pump suction/pressure lines that go to and down the well to the jet body and foot valve.

Water running down the outside of the cellar wall etc. wall can be running into the cellar through the pipe rather than your well lines leaking. If they were leaking you should have a problem for the pump to build pressure and maybe air in your water.

Check that your rain gutters aren't overflowing (clean them out if they are) and that the down spouts take the water away from the cellar wall like 3' or more. That keeps the water away from the cellar wall.

Yes, that is my point. The water may be coming thru the opening in the conduit that the well lines are running thru but where IS the opening?
And I do actually have a crack in one of the lines on the inside and the pump still works without leaking. LOL Can't explain that one.

thanks

Usually a conduit pipe will end across the area where the footer was dug (3 or 4') and then stop and then just the two lines would go to the well but... a lota girley men today are afraid of everything and one could have had it run all the way to the well "in case I ever have a line leak I don't have to dig up posies and my lawn"... without thinking of any opposit reaction like water running into the basement someday.

IMO they should have used PE pipe and no conduit because you can't keep conduit from running water into the basement sooner or later. They probably ran conduit because someone was afraid the PVC water lines would break going across the foundation excavation; which if not back filled and tamped properly first, they probably would have.

You could dry the conduit out and fill it with expanding foam and stop the water. Mortar may not do it.

It's funny you mention expanding foam because I had thought of the same idea. I think I will do that. Thanks!

Ok, I managed to drill a tiny hole in the outer pipe and sprayed expanding foam into it for minutes. No way to know if it sealed of course till next Winter probably. I only have a problem when there is near 2" of rain in the recent 2 weeks. Also, the Winter has a whole different dynamic to the way water flows and get absorbed. Just by digging the hole may have changed what happens. I was wondering if maybe I should have drilled a second hole further away from the house as a drain hole but then realized it may have been a source of water to come into the basement also.

Hey, I tried anyway. Thanks again. :-D

I expected you to spray the foam from inside the basement, not in the pipe outside the wall....

How far outside the wall have you dug up this pipe? If more than 3' I would start thinking the pipe goes all the way to the well.

You need to know if you have a leak in one of the lines and if you do you need to fix it, they get worse and all of a sudden you have no water. Especially with a two line jet pump, and you can ruin the pump if you run it dry for more than a few minutes.

The pipe barely comes in thru the wall... maybe 1/4" and it's all sealed but I suppose I could drill and spray it there if I had to. I did not dig more than 18" from the foundation mainly because there is a sidewalk and you are talking about a lot of work. LOL I was also getting nervous about the foundation not being supported and wanted to throw the dirt back in before any more rain came although it does look clear for days right now.

The pump does not cycle very often, and does not run if no water is being used so I think I'm ok for now. I did try to seal the crack in the return line. Like I said, I can't see how it's even working. Maybe it was replaced with a single line type pump. It's a Sears A.O. Smith.

The foundation is the footer under the bare wall you were looking at, the wall can't fall down.

I suspect there is something around these two pipes in the conduit so you can't spray foam into the conduit or you wouldn't be mentioning drilling a hole in it.

If you have a leak in one of the pipes, the conduit is going to fill with stagnant water, and that can contaminate your water so you need to find and fix the leak. I hear ya but that's regardless of how much work it is. You may have to dig up around the well down to the line and see if the conduit runs all the way to the well. And I wouldn't backfill your hole until the whole job was done.
