I have one full bath upstairs and a half bath downstairs.
When I took a shower this morning, the tub drained just fine... (quickly even).
Late this afternoon I raplaced the downstairs toilet.
This evening my kids took a bath and when they were done the tub drained very, very slow... extremely slow.
Could replacing the downstairs toilet have anything to do with it... venting problem maybe?
Any help would be greatly appreciated.
