"Very glad we got the drain pipe fixed! Mohamad did a very expert job in replacing the drain pipe and ensuring that it's sturdy and leak free. I can see the drain pipe with the camera and it looks like he built a highway with pipes! I can see the supports for the pipe, and they are very solid and strong. I am glad this is a permanent solution that I know will pretty much last forever. "
