Back in November of 2005, we had issues with our toilet not flushing. We thought it was because the toilet was just old (we had exhausted every other effort). We went out and bought a new toilet, and upon removing the old one, we found a plant whose roots ORIGINATED just under the wax ring. It was growing down into the toilet drain pipe - here is the picture from '05: Over the past few months, the toilet would drain slowly. We plunged, we snaked, we blew out the clean-out drain with a blow bag - everything. We called a plumber, who used an auger to go down the drain and pulled out some large clumps of gunk... and also told us to replace our wax ring - that it might be old. The toilet flushed for about 24 hours, but when it began to slow again, we went and got the wax ring replacement. Upon removing the toilet to replace the wax ring, there it was AGAIN! This time - more than twice as long! Here is the newly grown potty weed from today: The coloration in the picture is only different because this time, I used my cell phone to take the picture. Can anyone tell me WHAT plant grows away from light and how to kill it permanently? Has anyone ever heard of this before? Is there any kind of "professional weed person" who I can ask? I have searched the Internet and keep coming up blank.
