Drain Cleaning

I had a remodeling done and the handyman just left several problems open which I am doing now (basically you get what you pay for).
My latest problem is Bathroom sink. He left the drain disconnected.

I connected it but I see that water is flowing back. My guess is the drain line is blocked. It should be just a few feet because the main drain is open (no other source is backing). Had the exact same thing for the shower (dust, rust etc caused the block) and I paid a guy to clean it.

I am wondering if I can do the cleaning myself. I can buy one of those 25 feet drain auger that connect to drill.
Did anyone do that ?
What are the risk ? The plumbing is Cast iron.

Usually the clog with cast iron is just inside the wall in the tee.
I've had that same problem at every drain. A 25' auger snake works well for me.

Sometimes the stack is not directly behind the sink and the drain goes into the wall..... into a right angle and then to the tee in the stack. The right angle and tee are both suspect.

Snake I use. Manual powered..... not drill

Thanks PJMax .... I would ask one more question slightly unrelated but you are the man
The wall drain has a rubber (or PVC) clamped. The old P Trap was 1 1/2 " , and was cut. to connect.

Basically, the rubber connector is 1 1/2" but the actual drain is 1 1/4" . So the 1 1/2" P Trap gets just inside that rubber connector (about an inch or so) and then wrapped by the steel clamp.

I thought of replacing that and use a new connector (1 1/2" to 1 1/4") so that I can connect a 1 1/4" P trap with longer pipe inside the drain, but unable to take off the rubber connector. Any tool that I should use to take it off ?

I have pushed the 1 1/4" P trap inside but it is not snug fit and leaking.

That second rubber adapter is what you should be using. It doesn't look like the current coupling is actually doing anything except clamping around the galvanized pipe. It's leaking because it's just sort of shoved in. (Shoved in is fine, but you'll need the rubber coupling as well.

As far as I can see, the PVC is just shoved into the pipe. Maybe he used some kind of glue or something? The rubber clamp should be able to be loosened (two hose clamps on the right side) and wiggled off.

Right now the new PVC is just pushed into the old pipe because it's1-1/4".
His old trap was 1-1/2" so it fit into that old rubber coupler.

Be sure to clean the drain before adding any new fittings or the trap.

Right. As of now, it is just shoved in because I would not take the connected off even after loosening the clamps (actually removed the clamps) . Here is a picture of the old P trap (showing where it is cut and goes inside the rubber connector) . Will try to take off the connector with plier

That was a "Hail Mary" repair currently in place.
It looks like the steel is in bad shape. May be tough to repair.

I did the cleaning today .. lot of dust and debries inside . Made a discovery --- the pipe is PVC , not caste iron like what I Was thinking !
Still trying to take the rubber connector out (probably will need to cut it) but now I think I can simply glue to the drain (using primer and plumbers glue)
