I popped the top off my 4" well casing as i would like to add a clorinator to address iron in my water. I looked down the casing and there is some kind if seal 5' down with just the electric wires going through it. The seal closes off the whole casing and only has a small loop sticking up.
So my question is what is this seal and how do i get it out, a picture of one out of the well would be great. I,m not sure how i would get anything attached to the small loop on the seal.
Thanks
