your question was why would the plumber lie? because he is on the landlords crew of subcontractors the landlord uses for all his projects,so if the landlord dosn't want to pay, he'll make it happen. secondly there was no wipes,i pulled apart the tangled mess and found 1 sheet of paper toweling and aproximately 3 pounds of tree roots. the paper toweling is biodegradeable and should have passed through, if it wasn't for the roots it would have. thirdly i never signed a lease,i moved in as month to month,and i didn't know about the sewer problems. i've been here 9 years ,this is the fifth or sixth time this has happened with roots and this time when i called the landlord he sick of paying for sewer problems.that is why i believe he told the plumber to say it was wipes,when there were none there. lastly your comment about tree roots from a mile away is strange because most sewer codes require clean outs within 100 feet of residences, so roots from a mile away should have little affect on residences.
