I was wondering the same thing...
Owning a home is a huge learning process..
Im not knocking google search.. I just wanted another opinion on what should be done..
Infact I looked up zip it on you tube and saw a video of how it worked.. Spent 3$ at home depot and pulled it out of the drain..
Kind of like when people ask car questions, to me would be a stupid question since im a mechanic... And could just say "your cars broke, google "how to fix your car, If you write a check everytime your car breaks you will be broke fast."
But instead I help out and give my input on whats going on with it.
