Residential pools and commercial pools are completely different beasts. Residential service techs might visit 20 to 30 pools in a single day and only see a particular pool on their route once, maybe twice per week. For commercial pool techs, many jurisdictions require chemical and safety checks every day, if not multiple times per day. Both jobs require a strong attention to detail; techs must pick up on changes to pool operations very quickly during each short visit.
As a certified pool operator (CPO) instructor and consultant, I’ve spoken to countless pool operators over the years who lack an understanding of cleaning and disinfecting swimming pools. These knowledge gaps may be putting your facilities and customers at risk.
