Clearing lavatory vent stack

[Steve42]

A couple of years ago, I called out a plumber because both sinks in our guest bath were draining incredibly slowly. He went into the attic with a small electric auger and ran it down the vent stack. I know that he carried a bottle up there to lubricate the snake as it went down, and he said the clog was only about 10' below the vent stack opening.

The same sinks are acting up again and I'd like to try and clear it myself because I just changed jobs and haven't gotten a paycheck from the new company. I have a 25' sink auger that I'd like to try to use. I think it's one that you can connect to a drill rather than using the handle.

I would guess that the plumber was using dish soap, possibly mixed with water, to pour down the snake. Does that sound feasible?

I have not heard of using a lube. I was able to run water during the cleaning. Dish soap sounds good to me.

Here is my limited story cleaning a lavatory drain blockage.

Frequent and extended gurgling in our powder room sink

One inch. Also if the level gets lower, so even if you don't catch the event, you can tell water got away. https://www.amazon.com/Rectorseal-97402-Magic-Trap-Tee/dp/B002FY8ZIS/ref=sr_1_1 is a way you can put on an AAV for the bathroom and/or kitchen possibly DIY. You replace the existing slip...

Slow Drain - Trap Problem

I just installed an IKEA vanity where you have 4" of working room from drain/vent wall to back of drawer closure. Thought I had a nice neat solution ( see pic ) but alas found out the hard way that my U trap does not function the same as a P trap as I must have created an airlock and the sink...

My situation was that I could remove my strainer and I did not have a pop-up-drain rod to block the path. That will not be the case for most.
