Hi I am in serious need of help. I have an inground pool and my light cord is in a 100 foot conduit under the pool. The last time someone replaced the light he put some putty at the niche end of the conduit. The latest guy pulled the cord without removing the putty so now it’s stuck somewhere in the conduit. Tried pressure washer and a snake but nothing. Cannot get the new light line in. There’s also a ground wire in there already. Would love some ideas.
