GFCI (Ground Fault Circuit Interrupter) vs. Circuit Breaker

When we are in Chapter 14 (Facility Safety) of the  Pool & Spa Operator Handbook, discussing  electrical safety during our  CPO® class, we talk about the difference between a Ground Fault Circuit Interrupter (GFCI) and a Circuit Breaker.  We also define the difference between grounding and bonding, which you can read about here. The Circuit Breaker will interrupt (turn the circuit off) when there is a current overload.  This […]

Our Pool & Spa Operator Handbook lists a few things that affect the pH: the bathers the disinfectants we use the source water air-borne debris the water balance […]

Chloramines – Not a good thing

Chloramines – what are they? We returned to PoolCorp’s Anaheim facility, October 7-8, 2010 to teach a very large class of eager students.  In this CPO class (as well as in all our classes)  we talked about chloramines; what they are, how to prevent them, how to try to rid them from the pool, and what to do if they persist. Chloramines are result of […]
