I had five levels of service to choose from. I chose the the second lowest. I think it was about $100 more than the lowest. From what I understand, this extra $100 bought me the plumber filling my sink with water and draining it a few times as a “flush” of the pipes. I think I’d rather handle that myself and keep the $100. Previous plumbers snaked the drain just as much as he did, without the extra fee. I also got a 6 month warrenty on the sink, but as it has only been clogging every 14 months or so, I don’t think I will be using it.
