I have 4 toilets, and all of them appear to flush slowly. They are older toilets (huge tanks), so there is definitely plenty of water going in (the bowl itself almost fills with water). It swirls around for a definite long period of time, until it finally flushes. I just got the house, and at first I shrugged it off; but now I'm starting to really notice it and I'm getting paranoid.
Is there any way for me to confirm that this is a backup in the mainline? If so, what would be my best recourse to fix this problem?
I don't think I need to hire a plumber, but I'm just afraid there is a big clog in the mainline. I had a friend who's sister kept flushing her feminine products down the toilet, and one day the mainline just burst in the basement and they had a bunch of sewage in the basement... which is really what I'm the most paranoid of. I am living with 3 other guys, so if this clog is building up, I'm really afraid of just a lot of crap exploding somewhere...
Another possibility is just that all of my toilets release water too slowly into the bowl-- I read somewhere that I should get a 2-3 gallon bucket and just dump that water all at once into the toilet bowl to see if that's the problem. I plan on doing that today probably, but I just figured I'd get this question posted first in case anybody had some anecdotes or advice for me
