"I contacted Rema on Saturday. He got back and came on the next day. He removed his shoes. He installed a new flush valve that I supplied. He had to replace the existing fill valve. The existing fill valve would not fit the new flush valve. He clean up and there were no problems. It worked fine."

"BFMD is the best sewer line cleaning service I have ever used. Several other contractors insisted that I needed a new sewer line and quoted very high prices. BFMD determined this was not necessary and was able to clear my line completely. Great job, great service, great professionalism, and great honesty."
