The plumber who blocks drains while unblocking them.

https://imgoat.com/v/194003/KINbU85 Basically this is what I pulled out of my bathroom drain yesterday. In 2006, I was renting the house out and the tenants wanted a drain unblocked and said they had a friend who was a plumber who would do it for me. I was living a fair way away and just said ok. So he's unblocked the drain and recapped the cement cap on the drain and I paid him. But what did he use as a baffle for the mortar mix around the drain? Apparently he thought it was great idea to use a scrunched up tube of plastic a metre(3 foot) long to jam in around the pipes. the level of idiocy here from a person working around small pipes where water has to flow freely is not to be underestimated. Of course the mortar stuck to the top of the plastic and the rest gradually snaked down the drain, catching up hairs, grass seeds(which turned into thriving roots that grew along the plastic) and who knows what else people have put down the vanity basin and shower outlet. A lot of it didn't look too healthy and that's putting it mildly. Not all of what I pulled out is in this picture, not by half. I unblocked this drain with some thick fencing wire I had laying around which I curled into a hook at the end and basically fished around hoping for the best. Initially I used a wire coat hanger but it wasn't long enough and not strong enough either. So there you have the culprit of why the bath/shower and vanity have been backing up for the last few years. Why didn't I fix it before? It wasn't really a big deal until the last year and I accidentally knocked the pipe cap mortar yesterday while doing something else and broke it and a small piece(so I thought) of plastic caught my eye.
