Best Battery Backup Sump Pump in Washington DC

I called Roto-Rooter and Mr. Min arrived within one hour of my call. He quickly diagnosed the problem. He explained how my system worked. He tested the pipes both upstairs and in the basement to see why the dishwasher and garbage disposal were not working. he had all of the necessary equipment with him to complete the job quickly. I was very happy that I did not need to purchase a new unit. Mr. Min and Roto-Rooter did a great job.
