We have two new SK60 submersible sewage ejector pumps in our holding tank at a 28 room motel and they keep clogging up with things like plastic bags, string etc. . What can I do to prevent this?

Sorry SDmotel... besides directly asking patrons (or hanging small signs) to be aware of pump system or distributing brochure that acknowledges positives and negatives of staying at the wonderful SDMOTEL, etc. etc... There is nothing available on market that will help with customers visiting DAILY, weekly, monthly (;) ) or as tourists?? With this issue... that I know of anyway.

Give others here a chance though... maybe they have an idea. Good luck. Mark
