My toilet is at least 5 years old and about a month ago it began to not completely flush
out the stool. It will flush out the stool just about every other flush. I have tried to plunge out any possible obstructions to no avail. I checked the ballcock and it appears to function properly with seemingly plenty of water pressure.
the toilet deos not leak or seep.
Could there be a problem with blocked ports that force water into the stool? Help. Thank you....
