"I was very pleased with Remedy for installing a ZOELLER sump pump. That brand was highly recommended by my brother-in-law who happens to be a Master HVAC. The replacement took just over an hour by an experienced service technician. When completed he fully explained the operation of the battery backup. I would highly recommend Remedy for sump repair and/or replacement."
