I've never written a review for a plumber before, but I wanted to acknowledge great service when I receive it. The plumber Roto-Rooter sent out to my house in Seattle, Chhaylee Khat, showed up on time and went straight to work unclogging the side sewar drain. I recommend him highly for his professionalism. He knows the business and I think would make a good teacher for entry level workers just starting in this type of work. It's not a glamorous business, but can be very costly for the homeowner. All the more reason to have somebody you trust do the work and not take advantage of a situation where you can't do it yourself and must have pros do the work.
