Boy do I have a day ahead of me today. I was canning jalapeņos yesterday and overloaded the disposal with the scraps which plugged the branch line in the basement. I found the first problem when I ran a snake into the clean out hole in the piping under the floor. Who ever plumbed the house ran the branch line up hill over the A/C ducts.
Back when I worked in a power plant I worked with a lot of steam fitters. They used to joke that all you needed to know to be a steam fitter was;" poop doesn't run up hill and pay day is on Friday". Whoever plumbed my house wouldn't have made much of a steamfitter.
So, I am doing some heavy duty plunging at the kitchen sink trying to bump out the plugged place in the branch line and water starts running out of the wall behind the kitchen cabinets, bummer. I guess my less than able, not qualified to be a steam fitter, house plumber didn't know too much about using glue on PVC joints either.
Now I have two problems, a leak in the wall I would have to destroy part of my kitchen cabinets (with brand new granite counter tops) to get to and a plugged branch line in a tight place that runs up hill.
I think I will just cap the leaking line where it goes in and out of the wall and run a drain from the sink straight down into the basement to the branch line through the back floor of the sink cabinet.
Plan "A" for the uphill line will be to cut the insulation off the A/C duct to make less of a hump for the branch line to cross and pull up the pipe supports to try to get a down hill slope, it is in a very tight space with little room to work in.
Of course I could call a plummer and kick back in my recliner while he fixes the mess, with my luck I could get the same guy who created the mess in the first place, better do it myself.
