How do you stop basement waterproofing sealant that is coming into the sump pump basin from the foundation drain pipe?
I just called and spoke with the housing inspector who had been out here inspecting the contractor's work and he said that it's normal for some waterproofing material to make its way down into the foundation drainage system after a basement wall waterproofing job. He said that I will probably need to keep cleaning off the sump pump for another 2-3 weeks and then it will stop coming in and everything should be good after that. He said that he had spent many years as a new home construction plumber and that he often saw this issue happen whenever there was a long period of days with heavy rainfall right after a waterproofing job had been completed.

EDIT

Update: I decided to buy heavy tarps from The Home Depot and I placed these outside along the length of the two basement walls that had been rebuilt. I did this to stop any fast moving torrents of water that were probably coming down off the siding and then flowing down along the basement walls stripping off the waterproofing tar and then depositing it down around the foundation drainage system. So far, there has not been any tar coming into the sump pump basin. I hope that the hot dry summer weather will now cure all the tar on the basement walls and I can then remove the tarps.
