Per YouTube video the dude said. 3 footer would be adequate and it was.
To best of my limited knowledge " no"
No, 3ft aren't telescoping. They are just Long enough to clean out the toilet itself and a very short bit after(less than a foot). Look at a YouTube video for proper use
This is also known as a closet auger. That should be enough to tell you where to store it.
No. This is for toilets. They make smaller ones for sinks.
Not sure. Check google or YouTube. There may be ways to soften soap. I read that dishwashing soap in toliet followed by hot water helps lubricate toliet and may allow soap to move.
No. It is designed specifically for toilets and would be too awkward to use for anything else. The snake part of the auger is too large in diameter to use in sink and tub drains and too short.
Can return within 90 days. Home Depot.
Rise it off with garden hose outside and spray it wd40 to keep it from rusting
Anytime you're dealing with toilet/sewer issues it's recommended that you wear eye protection, long sleeves, pants and closed toed shoes or boots. However, using this you should be fine with just gloves.
