I told my wife that soon I will find a DIY on YouTube and give it a go. She isn't keen.
Been there... still there...
If you do end up attempting to lay drain lines, just remember... it's a 1/4 inch per foot slope back to the stack.
And, for personal experience, Diablo blades and a sawzall work quite well for cutting through cast iron pipe. But make sure you leave enough pipe left close to the stack to attach your PVC...
And closet bends are a pain to align properly.
And don't set the house on fire with the propane torch.
My house was built in 1928, much of the original piping was leaking when we moved in... the previous owners stuffed insulation into the kitchen ceiling and repainted everything to hide the known issue. 18 months later, the kitchen ceiling was dripping water from completely corroded 100 year old galvanized inlet pipes.
I think i will be too scared of leaks from the second floor to do the plumbing myself... if I had more resources, to cover my screwups, perhaps I would :)
I had fears about this, but figure - screw it! Take the risk.
The house I grew up in was built in 1926 and the wiring running through the ceiling was wrapped in cloth :D
Similar experience...
I was the bad kid in the family, and had the benefit of always being told to:
And so, I learned how to sweat copper pipes, fix cars, hammer nails, put shingles on a roof, run electrical wires, and put together PVC drains. It's still scary doing it myself though. And I don't have the time to do all that and also all the rest of the day-to-day tasks.
It always hurts my ethos when I need to pay someone to do something I know how to do, but don't have the time... I usually need to pretend I don't see all the things I would do differently.
I wish I had a been a bit older when my granddad was still kicking around, he was skilled in many things and was willing to show the ropes. Many of the skills that are valued these days aren't overly valuable skills - designed to make money - not create things.
