Kitchen drain system back up the night before...spent the evening and early morning with the Home Depot drain remedies, with no success. Googled the smell good guys, and got a quick response and appointment... Daniel arrived, told me about the $99 approach, which I was less than impressed, and he sold me on the high pressure clean out. Being an engineer I knew this was the correct way of doing a drain...The tools for the high pressure are more involved, than a typical snake, but level of labor effort to use the high pressure is about the same as the snake, and does not warrant the cost of more than 4x the $99 drain clean... I still appreciate Daniel and his approach and completion of the job...
