I had my house plumbing system redo years ago and heard water dripping sound from underground when I remodeled a bathroom. I then realized water had been leaking for a while. I searched for a plumber at CCYP and decided to call Mr.Lee. He came quickly and inspected the pipe and found out there was an incomplete seal around a pipe joint causing water to leak. He fixed it. Problem solved. I found him very professional and explain the problem in detail. Highly recommeded.赞!赞! 赞!强烈推荐
