Schedule of pipe most commonly refers to the thickness of the wall of the pipe itself. ex...schedule 40 PVC pipe has a thinner wall than sch. 80 PVC
The difference between schedule 40 and 80 pvc is the wall thickness and schedule 80 is thicker then schedule 40 so the higher the schedule number the thicker the wall of the pipe thus can hold more pressure.
It is the wall thickness heavier then schedule 20 lighter then schedule 80
A junior saw is a saw that is used to cut PVC and metal. The blades for it come in different sizes depending on the material you are cutting.
I can't imagine the plumber only giving 1 year on the PVC. Cast iron is rough on the inside and those rought spots can snag paper, lint, etc, eventually leading to blockage. PVC should last much longer and be less susceptible to blockages from material getting caught on the inside wall of the pipes. Also, PVC doesn't rust, while cast iron will. All-in-all, I'd have to vote for the PVC (make sure that it is at least Schedule 40 PVC).
A sleeve is anything that protects the pipe from something else you can purchase special sleeving for copper or pex in slabs, sleeve an irrigation line in a driveway with PVC or use PVC between floors of a concrete building.
To connect PVC pipes to metal pipes using a PVC to metal adapter, the best way is to follow these steps: Clean and prepare the ends of both the PVC and metal pipes. Apply PVC primer and cement to the PVC pipe end and the inside of the adapter. Insert the PVC pipe into the adapter and hold in place for a few seconds. Repeat the process for the metal pipe end and the other side of the adapter. Allow the connection to dry and cure according to the manufacturer's instructions before using.
To properly connect PVC conduit to a metal box, you can use a PVC male adapter and a locknut. First, insert the male adapter into the end of the PVC conduit. Then, thread the locknut onto the male adapter and tighten it onto the metal box. This will create a secure and watertight connection between the PVC conduit and the metal box.

Answer replacing cast iron with PVCThere is a rubber sleeve available that goes in the cast iron and then the PVC slides into it. Use a rubber outside sleeve with two hose clamps. You can also replace the rusted section with PVC and them "lead" them with the packing and a paste sealant that is made for this.
PVC (Polyvinyl chloride) is a type of plastic polymer and is considered a non-metal material. It is commonly used in construction, plumbing, and electrical applications due to its durability and flexibility.
It will connect to the PVC pipe into the wall which ultimately will connect into the main sewer line outside.
PVC conduit is better then metal as it won't corrod under ground and theres less of a chance of electrical shortages.
To effectively repair PVC pipes, you can use a PVC pipe cutter to remove the damaged section, clean the area with sandpaper, apply PVC primer and cement, and then connect a new piece of PVC pipe using a PVC coupling or repair sleeve. Make sure to follow the manufacturer's instructions for the primer and cement for a secure and lasting repair.
To connect a metal pipe to a PVC pipe using a metal to PVC adapter, the best way is to first ensure that both pipes are clean and free of any debris. Apply primer and cement to the PVC pipe and the adapter, then insert the PVC pipe into the adapter and hold it in place for a few seconds to allow the cement to set. Repeat the same process for the metal pipe and the other end of the adapter. Allow the connection to dry and cure according to the manufacturer's instructions before using the pipes.
PVC pipes are less expensive and easier to repair. Metal pipes are more expensive and more difficult to repair.
There is not much difference, however, plumbing PVC has a thicker wall, for obvious reasons, namely, water pressure.
