The basement floor drain is having backup after the wash cycle from the washer, it doesn't backup from other water usage.
I had a plumber came in to power snake with 1/2" tip (and few other tips) into the floor drain for an hour without success. He suggested the only solution is to break the concrete of the floor and replace the blocked piping.
Is there any less aggressive or cheaper solution I should try first? Someone also suggested me to hire other plumber who has optical device to look at the blockage in the floor drain pipe (for a full diagnostic), do you think it's useful?
