bathtub drain leak

[duongz]

i have a leak at the elbow of the drain. i think its the limescale/calcium bluish greenish buildup thats causing the problem but im not sure. i cleaned up it up the best i can. its hard to reach,i would have to cut some drywall in the basement to fully access it. the tub is upstairs.

i made the mistake of putting water weld around it but that didnt work. if i were to cut the drywall, would i be able to remove tha wastepipe/tail piece from the elbow to clean it or is that permenatly attached. option 2 would be to replace the tailpiece and elbow with pvc which oesnt build up and leak that much i heard. is there any option where i dont have to cut the drywall

i was also wondering if me using bleach to kill tub mold could cause the leak, i flush with water afterwards. i heard its ok as long as u diltue it

You may be able to accomplish this from the photo access.

You just need the drain shoe; https://www.amazon.com/Eastman-3522...prefix=bathtub+drain+shoe,aps,100&sr=8-2&th=1

Make sure you measure before you buy.

They are available in brass, PVC and ABS.

Yes, bleach is a good anti-mould agent, but it will not dissolve lime buildup, causing your leak. It is not a good idea to cut drywall to clean it. It's better to replace the sink tailpiece. PVC is a good option, but you might need to replace other parts. For example, if your faucet has lead, then you should replace it too. The best is to contact a plumber, and they will be able to give you a free estimate.
