About a week ago my kid tells me a shampoo cap went down the bathroom drain. Low and behold the drain is stopped up now and can take hours for water to get out.

Home is older and most of the plumbing is copper pipes.

Had a plumber come out and say they would have to cut and remove the pipe and then replace it which would cost over $700. We have a basement and it’s in a crawl space.

Tried a snake and snake gets jammed about 8-10 inches down presumably by the plastic cap.

Any other options other than paying the plumber to cut and replace? Is there any drain cleaner I could use that would melt plastic without damaging pipe?
