My question involves personal property located in the State of: Illinois in the county of Madison

Hi, Sorry this is so long but there is quite a bit of background. I bought my house 4 years ago in the winter. In the spring my basement started flooding. I called a plumber as it was leaking in through the foundation & floor joint and from around the sewer lines exit through the foundation. It was a finished basement. the whole thing was a loss, carpet drywall, furniture, storage etc.
My basement is big, 38*54 all finished except a small corner for laundry/utilities and a small wood shop maybe 15*10. Had 5 plumbers out, they couldn't find any clogs in the drain. While talking to the last one we were walking the yard and I noticed under a landscaping rock that I indeed had a clean out contrary to what the last owner told me. We discovered a small ball of grease but nothing big enough to clog the 6 in line. We removed it and it quickly turned fall and no more water. It has flooded every year since then.

The next year I spent building up the ground around the foundation, still flooded but not as bad, That side of the house is about 3 feet from the property line and the other house is about 3 feet from there. I noticed water building up around the area of the water coming in one day and since My roof does not flow that way it had to be a leaking gutter from the neighbor. So I asked him to fix it and he did after 4 months. Now here is the key, the start of this year my neighbor moved out and the house is for sale. I noticed that a hose was sticking out of a hole where the foundation and the siding come together, I had seen the hole before but never a hose sticking out. I noticed it draining water and since they were not completely out if the house I saw them regularly still, I said something and he said oh that's been there for 3 or 4 years. I asked him to reroute it as it is real close to my foundation. He agreed.

It pumps out enough to keep me hauling 5 10 gallon shopvacs every 2 days. He still owns the house and comes by on the occasion and I have left him 3 notes asking him to move it as it is flooding my basement. I firmly believe that the year we moved in he started pumping water out in between the houses. I think I never saw the hose because he only put it through when he knew I wasn't home and pumped the water out. Since he moved the hose has to stay all the time and the pump operates on auto now.

Do I have any recourse, is my neighbor possibly liable for all/some of these damages?
