I have used Rainbow Plumbing & Heating on numerous occasions and they always do a great job. They have cleared clogged drains for me, and worked on my air conditioning and heating system. They have also taken care of a root problem in the sewer line. They come out periodically and pour the root killing solution in the pipes to keep that line open for me. They are very nice, friendly people, and they are always respectful to my mother. I have been very satisfied with them!
