...I kid; really it was a low, low $951.00 American. Roseholme now has a free-flowing sewer connection (in the "away from house, to sewer line" direction) and a whole new floor drain. With flood-stopping valve.
He did run a camera down the drain and after chasing the roots away, it looks, I am told, "okay." The roots will, of course, return, especially in this drought. (He offered to "come back and scope the drain when you can see it." What, his employer never heard of DVRs? DVD recorders? VHS tape?)
They tell me I could get a fancy, lifetime-guaranteed resin relining of my sewer connection for only $12,000.00 and change. That's nice. I could also sprout wings and fly to the tops of the trees -- in fantasyland. Here in reality, I don't have that kind of cash and if the drain does fail catastrophically, I will be having to take Desperate Measures. Which makes me just like most people.
