You can't. There is no fitting to do this. Galvanized has to be threaded.
To effectively connect a galvanized pipe to PVC in a plumbing system, you can use a special fitting called a transition coupling. This coupling has one end that fits onto the galvanized pipe and the other end that fits onto the PVC pipe. Make sure to clean and prepare the ends of both pipes before connecting them with the transition coupling. This will create a secure and watertight connection between the two different types of pipes.
To effectively connect galvanized steel pipes to PVC pipes in a plumbing system, you can use a transition fitting specifically designed for this purpose. These fittings have one end that fits onto the galvanized steel pipe and the other end that fits onto the PVC pipe. Make sure to clean and prepare the ends of the pipes properly before connecting them to ensure a secure and leak-free connection.
Pipe dope and/or teflon tape
There is a coupling that almost all plumbing stores should have(including lowes). Its name can vary but is commonly called a dresser coupling or a raybolt.
Yes, this shouldn't be any problem to do.
It will connect to the PVC pipe into the wall which ultimately will connect into the main sewer line outside.
Yes, with an approved adapter fitting.
To repair a PVC pipe, you can use a PVC pipe cutter to remove the damaged section, clean the area, apply PVC primer and cement, then connect a new piece of PVC pipe using a PVC coupling or repair fitting.
Male or female sharkbite adapter on threaded end of galvanized pipe or fitting. No other way.
Depends on local codes and the PH of the water
Abs to PVC glue sold at home depot Color it aqua blue/green plumbers key term. GUMBY GLUE Depends upon what you mean by "black pipe". If you mean ABS drain pipe, there is glue for that. If you mean steel "black pipe", i.e., non-galvanized, then you would need a threaded connection adapted to the PVC (either a female PVC connector on a male black pipe or a male PVC connector into a female black pipe fitting). The secondary question would be, "Why would anyone want do to that?"
