This is a real puzzle, and I'm hoping it isn't something bad :/
Just purchased a house 'as-is'..... already closed on it and the deal is done. Its a small house that was divided into a duplex.
The second floor residence is reached by outside deck stairs.
What they did was, they closed off the original stairs as a closet inside the house. And on the landing of the stairs, inside the closet--- they put the water heater for the upstairs apartment. So the water is split into two meters, and two water heaters.
Now, the sink, toilet and shower upstairs, as well as the kitchen faucet have been run all at once, for a long period, flushing, etc. And there apparently is no blockage at all- the drains are working fine.
Except for one thing.
Obviously they added these drain pipes for the upstairs and connected it to the main stack. They look to have rusted through and been patched. After running the water for a long time, everything drains as I said, but there is some slight dripping coming from the drain stack here for awhile, every time.
What I'm worried about, and the only possible thing I can think of..... is that water is backed up and sitting always in the drain stack, sort of like a giant sink trap. And maybe it moves, when the faucets/toilets are used upstairs?
Maybe by an ill-thought-out drain stack assembly?
Or am I overthinking this.
How could the main stack be dripping, and apparently..... rusting through like this?
