we suggest having the pool water tested by a professional (often free of charge) once a month.
The water of the pool or spa must be maintained within the standards included in this manual. Any negligence to do so, will void the warranty. These standards are from the NSPI and are common throughout the swimming pool industry; they are not particular to Turcotte heat pumps.
The most important factor for the durability of the pool heat pump is the pH because the capability of the water to cause the degradation of metal is directly related to it. Let’s also mention that TA is the measure of the capacity of water to resist to pH variation; therefore it is as important. Taylor, an important manufacturer of pool water test kit for professionals states:
“Corrosive water will dissolve copper piping and heat exchangers and leave stain on pool walls.” [Taylor, A Testing & Treatment Guide part #2004B, p.35]
“The result is a highly unbalanced water condition resulting in damage to copper heat exchangers, light rings, stainless steel ladders an concrete pool surface.” (Talking about acidity and low TA) [Taylor, A Testing & Treatment Guide part #2004B, p.11]
Below is a chart presenting pH associated to concentrated solutions of various chemical products for pools.
