The installation of the entire pool was fantastic! But I found out 2 years later that no one installed a back water valve on the pool heater! Result is recently I had to pay an HVAC guy $3200 to replace the heater as the salt water eventually made its way into 3 burners destroying the unit! Also my light in the pool worked for the first 6 months and then gone! Apparently it costs $500 to replace it!?! NOT HAPPY!!
