Be informed;
I called to have the Roto-rooter service clear a residential floor drain in our basement. I nice fellow showed up on time and ran a snake down the drain about 10' clearing it for the time. Water flowed all appeared to be fine. With-in days I began to notice that the sewer was backing up a little bit and flowing slowly. I kept an eye on it and tried to figure out if it was related to a specific line. Dishwasher or washing machine etc. I called rotor-rooter service again and a different nice fellow showed up and this time he ran the snake all the way down the entire drain aprx 40' to ensure that the whole pipe was cleared. Not just the first 10' like the first guy did. This took aprx 10 min more than the first guy and ensured the pipe was fully cleared out. I paid the guy and then called rotor rooter to ask why the first guy didn't snake out the whole line the first time as the second guy did. The response from rotor rooter Ken was the first guy went down 10' figured it was cleared out and there was not reason to go further. When I asked why the first guy didn't just go down the full 40' like the second guy in the first place he just got plain upset and after a short rant hung up. I will leave you to make your own conclusion but that's my experience. I recommend requesting Bill.
