I called late at night for an emergency call because my sump pump and back-up sump pump backed up because the line was frozen outside. My basement was flooding at a rapid pace with a lot of damage to items in the basement. The phone operator told me she would send someone immediately. As my wife and I were bailing water out of the basement Dave B. arrived in about 20 minutes. He knew exactly what to do and replaced my outside line with a temporary hose. He checked out the 2 indoor sump pumps to make sure they were working, made some suggestions, and even helped me with my water softener that I was having problems with. Dave was amazing!! He saved us from so much water damage that could have occurred in the basement.
