I called Santos after unsuccessfully trying to deal with a bad smell coming from my basement floor drain.
I cleaned the parts of the floor drain that I could reach and removed a large ball of floating grease but there was a dirty submerged 3" side pipe that I could not access. The smell got worse every time I ran the kitchen faucet and there was gurgling and water movement in the floor drain. I brought Santos in and Silverio very quickly realized that the gurgling was caused by water back flowing from the kitchen drain into the floor drain due to a blockage, caused by kitchen grease.
Silverio gave a very clear and concise explanation that made complete sense based upon all of the symptoms, and he recommended that the drains be snaked to clear the blockage. The "before" video showed that the drain pipe was full of dirty water, while the "after" video showed nothing but a clean pipe with a clear stream of water running at the bottom. The water level in the floor drain returned to its proper level below the 3" side pipe and the offending odour was gone.
Thank you very much Santos Water Service & Drain for your very efficient and professional service!
