/diy/ - Do It Yourself

>>2706592
I just now managed to fix it by chance because I had bought a new hose for the shower and it fit the bathtub faucet next to the sink. Apparently the problem wasn't in the pipe further in or at least it didn't look like it. After attaching the new hose, removing the plug and dialing the flow to max I jammed it up from below and rotated it to hit everything it could (hoping to get some pressure into the pipe and removing the obstruction). Loads of black sludge and hair came loose and landed in the bucket I had below it. Putting things back together it now flows clean and nicely.

It seemed like a weird design because it was double walled when I looked from below through the plug. The center was somewhat clear before but the outer layer was completely caked up. Right before the hosing I severely bent a toothbrush and scrubbed all I could, didn't seem to do a lot but might have loosened it enough for the hose to get it.

I tried disassembling it at first but this thing haven't been taken apart since this was built in the 50s and I was worried to break something when the force needed to get somewhere became too much.
