I live in an apartment building, can I use this to solve an issue where my washing machine drain stand pipe overflows?

I'm not sure what the difference between an apartment building and a house would be with regards to the washing machine drain. However, the main reason I purchased one of these from Home Depot years ago, was for that exact reason. It turned out that the rush of water from a washing machine drain is far more powerful than this unit can produce. What worked for me was 2 things. 1: I lengthened my standing drain so it was above my washing machine and 2: I put a rubber drain cap, like this one, https://www.homedepot.com/p/1-1-2-in-PVC-DWV-Flexible-Cap-PQC-101/100372302, on the top and cut out a small hole and stuffed the washing machine drain into it very tightly fit - cured all my problems!

How to connect the hose to the bathroom sink’s faucet? No institutions were given.

I bought mine in 2014. On the back of the package (model 340) there are instructions 1) Remove aerator and connect faucet adapter to faucet. Then connect hose to faucet adapter (If you did not receive the faucet adapter in your kit, you need to request they send you one). 2) Connect Drain King to hose. 3) Insert Drain King into cloggged drain. 4) Turn on water to clear drain. These are the instructions that are on the back of my package, which I still have. On the front of my package it says the package includes: Drain King 1-1/2 inch to 3 inch, Faucet Adapter, and 10 inch Hose.

In a Bathroom Sink, do you actually need to remove the curved waste arm/bend and insert it directly into the waste line pipe for it to be effective?

I WOULD BECAUSE YOU WOULD GET A STREGHT SHOT DOWN THE DRAIN LINE AND YOU CAN INSERT IT FURTHER IF NESSARY. YOY WILL ALSO BE ABLE TO SEE IF THE PROBLEM WAS IN THE TRAP.

Wouldn't the pressure blow the pee trap apart on a sink?

Dave, the pressure for the smaller units is high - but not enough to blow the pipes or connections. I assume that it is possible to have a completely stopped up sink whereby someone poured concrete down your drain. In that case, something would have to "give". But as long as your clog can be moved thru your pipes, this will do the trick. I use three of them in conjunction......kitchen sink, bathroom sink, and shower drain. So far, I haven't had any problems and all backups are moved thru leaving me with free-flowing drains. I hope this helps. I must note that I am not a plumber - nor do I have ANY plumbing experience whatsoever.
