Pretty messy and potentially serious situation. I called and spoke with Zack, at the Drain Flusher. This call was among 5 calls that I made and he was the only professional and I mean PRO that picked up the phone! He was reassuring about what he could do and did every thing he said he would, including being willing to come at 10pm and keeping the quote the same, even when it turned out that there were 2 blockages, inside and out! It was even touch and go there for a bit when it seemed the outside stack/pipe to the city might have been broken? I'm going to simply say, Zack went the extra yardage here! Thanks, Zack for being knowledgeable, honest, efficient and effective!
