Wow! 2 X the price in 5 years, probably mostly inflated in the past few months.
The guy at the hardware store told my neighbour that there isn't any drain pipe to be found, so I don't know how I'm going to put everything back together again without any new T fittings. He said there was no pipe, but perhaps they do have the fittings. I just hope we can find some! I'm still struggling to get the dirt out. I just made a makeshift auger from a tin can and some 1.5-inch black pipe. Hopefully the tin can is solid enough to move the dirt! I'll find out in the morning. The store-bought drain auger pokes right through without pulling any of the dirt out, so that's pretty much useless. A waste of $45.

If our dollar is going to be cut in half every few months going forward, I think we might be better off buying as much crypto as we can. I heard gold and silver were sold out months ago. Not sure how true that is though.

Actually, I'm not sore at all. I probably should be. Perhaps I'm just too busy to feel the pain?
In actual fact, the concrete was just 2 smallish sections. I used a diamond blade to cut half-way through (my discs are too small to go all the way through) and then a sledge hammer to bust away enough to get a small garden spade under the lip. With no soil to support the slab, I was able to chip away at it and make the hole bigger and bigger until I could get a proper shovel in there to really scoop out the dirt from under the slab. A few good whacks and it all broke up in the first hole.

I tried using a 5/8 inch masonry bit and a hammer drill to weaken the 2nd hole/slab, but that was too hard on my hands, so I only made about 5 or 6 holes and gave up on that idea. I went back to the diamond blade and cut through the series of holes (the cutting was easier following the line of holes), but the concrete was considerably thicker in this area, so breaking up the concrete to get my starting hole was quite time consuming. Then, even after I had dug out the dirt from under the slab, it took a lot of effort to get bits of the slab to break off. Then came the fun part... trying to expose the pipe without breaking it. The T in the 2nd hole is actually under concrete steps, so not much room to maneuver in there. The T was surrounded by roots with a couple of big ones actually going into the T itself. I managed to remove the T (in pieces - it's a crappy Big-O thin-walled fitting), cut the roots that went into the pipe and using a winch, pull 10 feet of roots out the other end. Unfortunately, the roots didn't pull the dirt out with them and I'll need to deal with that yet. Plus, about 7 feet of one root is still in that dirt. It broke off and didn't come out with the other length. However, since I have BOTH ends of that section open, I may be able to use water pressure and a hose to flush that section clear. The other section MIGHT go out to the street, so I don't want to push the dirt farther down the line. I'd like to auger that out if I can. I dug a hole where I expected the pipe to go but didn't find it there, so I suspect it turns and goes out to the city storm drains.
