I've never had this happen on a basement or slab, just in houses with short crawlspaces. Any bit of water that trickles down the outside of the flange causes the roots to climb up slowly. Even just condensation if humid air goes through the crawl and condenses on the riser.Have yet to find that here, but probably because slabs are very rare. Most homes here have basements.
That is an awesome story. That kid has probably remembered that his entire life, and now probably LHAO every time he thinks about it. He might have even told his mother years later and had/has a good laugh with her over it, He probably has always had a special place in his heart for plumbers. If there is a heaven I think you reserved your spot.Years ago I pulled a crushed up porn DVD out of the water way of a toilet, one overly interested 13 year old watching me the whole time. His mom asked what caused the problem: “advanced toilet calcification,” was my answer and I heard an audible sigh from the other room.
Poor kid nearly had a heart attack.
I have had customers who are the homeowner and are paying the bills get annoyed withy me for having the nerve to tell them not to flush them, no matter if it says flushable on the package. I tell them that yes, of course they are flushable, but they are not biodegradeable, and the wipe company doesn't care about them or their plumbing, all they care about is selling more wipes. One guy argued with me and told me that his doctor told him to use them. OK chief, see if the doctor is going to pay your plumbing bill or snake your lines. Same with recommending that they use single ply instead of quilted. Some of them act as if you offered to buy their 16 year old daughter.Eddie that sucks customers need to be educated on what not to throw down the sewer. Or possibly they don't care and are not paying the bills?
