The first question is simple: do you notice water around the base of the heat pump only while it is running, only when it is off, or all of the time? Pool heat pumps can make a surprising amount of condensation, especially in humid Florida weather.
Condensation can be normal
Under the right temperature and humidity conditions, some heat pumps can produce several gallons of condensation per hour. Water on the pad does not automatically mean the pool water circuit is leaking.
A simple chlorine check
One way to compare the water is with ordinary pool chlorine test strips. First confirm there is chlorine in the pool. Then test the water collecting around the heat pump. If the water around the unit has no chlorine, condensation is more likely. If chlorine is present, a water side leak becomes more likely.
Watch what happens when the heater stops
Another clue is to leave the pool circulation pump running while turning the heater off. If the water around the heat pump gradually stops and the pad begins to dry, condensation is the likely cause. If water continues, the system may need service.
