Slow drip on sewer pipe joint
A damp sewer pipe joint or extremely slow drip discovered during renovations often indicates a seal beginning to fail. While minor dampness may have persisted for years without issue, the transition to active dripping prompts homeowners to plan for pipe replacement before major damage occurs, though fixing it requires disturbing finished basement walls.

“Due to some work in my basement I now can see this place closer where one of my toilets lead pipe joins the main sewer pipe. I know for sure that it looked wet when I bought this home 6 years ago, but only now I removed some walls and can see details.”source ↗
“What do you think, and what the fix will require in case I need to do it? The bathroom that this lead pipe goes to is finished”source ↗
“Can these two still be connected somehow? Do I just need to buy a small adapter/fitting, or is the filter broken and I need to replace the whole thing?”source ↗
“Not very familiar with plumbing, so any help on what part I need would be appreciated.”source ↗
“Since then, One of those wet-looking seals has started an extremely SLOW drip. Like one drop a week level of slow. I'm in the planning process to replace the cast iron pipe. No reason to wait till it actually leaks”source ↗
“By broken plastic piece I am guessing you are referring to the white thing? If yeah, how can I remove it? I tried using my finger and a screw driver, it didn’t budge.”source ↗
