We recently had our bathroom redone and a new American Standard Colony Elongated toilet installed. The piping wasn’t moved at all, we just put a new toilet in place of where the old one was.

I noticed it’s only been a week or two and it’s already clogged twice. Is there anything the plumber should have checked for or could have done wrong during installation? We’ve lived in the house about 3 months and this wasn’t a problem in this bathroom before.

I did pick up a pack of softer toilet paper by mistake so I thought that might be the problem but our other bathroom toilet is handling it just fine. I don’t have 100% confidence in our plumber at this point, he already had to redo something in the shower because he used pex piping or something.

Also not sure if this is a coincidence but this is a toilet on the second floor. The bathroom on the third floor has a very slow-to-drain toilet. We don’t even really use it much since we moved in- this bathroom is next on our list to renovate. Could the problems be related? OTOH the 2nd floor toilet worked fine until we replaced it.

    What brand / model of toilet was used. Many toilets now advertise there ability to flush. If the model was not rated it may be the problem.

    I suspect the problems are related. Are vents in good order? Mar 15, 2019 at 13:22

  • How would I know if the vents are in good shape?

A lot depends on how severe a clog you have:

  • An extra flush gets it going

You may have a toilet that isn't well designed. A lot of earlier low-water-usage toilets had this problem. But there may be adjustments you can make to the flush mechanism inside the tank to increase the amount of water used for each flush.

  • Plunger needed, but nothing more

In this case, it is likely a clog "nearby" - e.g., perhaps something clogged the pipes during renovation and has narrowed the pipe a bit. And it could also be a vent problem (though I admit I really don't understand vents myself). But it would not be something "far away" as that would likely affect other fixtures too.

  • Snake required

If you need a snake to fix the clog then this is much more serious. Could be a vent problem (as I don't totally understand plumbing vents, I can't say more than that) or it could be a drain pipe problem farther down that is "catching" some waste from the toilet when it shouldn't.


Your plumber could have messed up the wax ring. Some toilets don't flush very well compared to others.

  • Thanks for the answer, but it isn't clear in your answer why a wax ring problem would cause problem flushing. Would you expand a bit? Thanks. Mar 15, 2019 at 13:57
  • i could be wrong about this ...... the siphoning action is probably being interfered with ...... i think that if the wax seal has a leak, then air gets sucked into the sewer pipe during a flush .... that prevents the contents of the toilet bowl from being sucked into the sewer pipe
