[QUOTE=Plan B]
One of our toilets is stopped up. I’m not sure what caused it. FWIW this toilet seems to clog up a bit easier than the others. So we have a rule that we only use this one for peeing. But the kids have friends over and all that.
Anyway I tried using the plunger for several minutes, something that had always worked before. This time there’s no sign of improvement.
I’m wondering if buying a new plunger might help. This one doesn’t bounce back into its natural shape after each plunge, so I think that might keep it from doing its best.
What about trying something like Liquid Plummr?
And what about waiting it out? We got by for years without this toilet. We only installed it a couple of years ago.

Your decision tree should depend on the age of your pipes, what might be blocking them, and whether or not there is a drain cleanout downstream you can get to.
If they are newer pipes (20 years or less, e.g.) all the way to the sewer connection and some kid didn’t toss a toy truck in there, you can get rid of poopie waste and toilet paper blocks yourself with plungers. Talk to a hardware store about the various types. You are essentially trying to push a soft mass until it reaches a larger waste pipe.
If the pipes are old (30 years or more, e.g.) then this is a good time to rod them out properly. You can do a reasonable halfassed job yourself with a rented rodder but the older the pipe, the more I’d lean to coughing up for a professional job. Old pipes accumulate a lot of debris that plugs up the walls and leaves narrow openings; the problem will recur until they get cleaned out.
If the problem could be tree roots then you got a biggie and that definitely needs a pro.
If you have a cleanout plug anywhere along the way, scope out the situation from there and see how far downstream the problem is. Be prepared for the fact that unscrewing a cleanout puts a (temporary) hole in the waste line, so if the blockage is distal to the cleanout, you gonna get poopie water comin’ out that hole cuz it’ll be backed out above that.
It’s fine to try drano, etc. Use the gel type. But if the pipes are old, a blockage can be a sign there is a chronic narrowing that needs rodding and not drano.
If the blockage is something non-flushable and not just Donnie’s Big Dump, then you need a pro unless it’s something like a brittle plastic toy that the rodder will easily bust up.
ETA: If you never use this toilet, consider whether something fell into the waste pipe at construction–that has happened to me. My lovely framers left a 2x4 block that I didn’t find until it overflowed 4 years after they had gone, cuz we never used that basement toilet.
