I adjusted the sprinkler heads so that they weren't spraying at all and dug up around them to expose 8" of funny tube, then cycled the sprinkler system, and made sure there weren't any leaks down below. I've now got them spraying nicely away from the house and zero leaks.
I also pulled back all the sod along that wall and filled with top soil where it needed to assure that there was a slope away from the house and packed the topsoil nice and tight to the wall.
After doing all this work and still getting a little water after a sprinkler cycle I really thought it was a problem of the lowest sprinkler head (back by the doorwall) was draining all the water in the system after a cycle, but now after that 15 minute rain storm yesterday and all the water that came in, I'm not so sure given the fact that the too numerous to count all day rain storms I've endured over the last four years went by without any problems. I'm not in a high water table. My sump pump only cycles during heavy rains.
I'm going to pull off some drywall to see if any insulation got wet and address any issues there, but I need a solution for the leak. Given the fact that so many "dry basement" companies are just pushing their system, what contractor should I call out first and is there anything I can do myself?
If it is a drainage tile problem, what is the best thing to do?
