I think I accidentally flushed a small grout brush down the toilet. I say 'I think' because it was in a bucket I dumped in the toilet and now I can't find the brush. The brush is about 4 to 5 inches long and maybe 3 inches wide. The toilet seems to be flushing just fine. I did notice a few small air bubbles come out of the water when I flushed afterwards but they went away with subsequent flushes. We plunged and nothing came out. The water went down as we plunged. Later we flushed some toilet paper to see if it went down and it went down fine. The toilet appears to be working just fine. Is it possible that the brush passed through the pipes or is this just the calm before the storm? Should we have a plumber investigate? Any advice would be greatly appreciated! Thanks!!

Don't bother with a plumber at this point. Depending on your toilet the brush may have made it past the integral trap in the toilet, once past that its likely home free. If you do eventually get a clog which your can't plung then call a plumber or at least a handyman.

Thanks for the speedy response and helpful advice!
