I recently purchased my 2nd new (very old) home. This home had 2 sump pumps installed. The inspector reported that the sump pumps were working, however, I have never even seen a sump pump. I purchased a sump pump tune up for 1 sump pump because I was worried about it being clogged and etc. The technician came, he was very professional serviced the sump pump I was worried about and also checked the sump pump I was not concerned about. He gave me the run down about the back-up battery and how often they should be replaced. He told me that both pumps look pretty new, however, he suggested that I keep an eye on it because I do not know the age of the pumps. Overall, I would use this company again.
