Customer had us out because he was interested in having a recirculating pump installed. After asking the customer about their expectations we made recommendations on the type of pump we should install. The customer agreed and we began work. We turned power and water off to the unit. We cut out a section of piping on the hot side. We installed the comfort pump and reconnected existing plumbing. We installed the crossover tee in the master bathroom. We turned water on, flushed aire from the system and powered of the unit. We ensured proper function then cleaned our mess and collected payment. No issues when we left. Also left estimates for water filtration.
