This Sina Plumbing did an excellent job. First figured it out the actual problem one by one methodically. Once identified, he does the great job of fixing it. After identifying the initial problem at the out side the house, he explained the problem, and started working on it, using his routing machine, sending it it almost up to 55 ft towards the road and cleaned it , repeating to and fro couple of times, to ensure, all the block is cleared. Then he repeated the same sending the routing towards the house, to ensure, there is no block inside. Then he used another machine at the inside of the house to do the suction of the block to clear the clog inside. Finally when he left he did the great job, of clearing all the clogs and smooth flow of water. Over all did a good job and I will recommend for everything. The price and quote is very good, and will never get, with my past experience.
