IF well maintained pool heaters can last for around 10 years. To increase the longevity of your heater the following steps should be followed: Keep your heater clean and as dry as possible. Sweep out beneath the burner tray and clean any leaves off of the heat exchanger. Trim back foliage around and above the heater to enhance the drying effect of the wind and sun. Don't mulch around the heater, which traps moisture. Keep rodents out by using mint sachets or moth balls during the winter.
Most salt chlorine generators have a salt cell that lasts typically from 3 to 5 years. Most salt chlorine systems come with a control panel or a self regulation system that will tell you when the cell needs to be cleaned or replaced. Its important to have your pool technician check inside your salt cell to make sure there is minimal build up on the metal plates. We recommend having your salt cell cleaned or replaced if you see any of the following signs: Blue/green soapy discharge forming inside the cell, scale and mineral salt deposits building up, or a chlorine level drop resulting in unbalanced water
Sometimes it's difficult to determine if low water levels are due to evaporation or a leak. You can discover leaks in your pool by conducting a simple bucket test. Fill a plastic bucket three-quarters full of water. On the inside of the bucket, mark the water line. Place the bucket in the pool, then mark the water line on the outside of the container. (If the bucket has a handle, remove it to allow for better stability while floating.) Let it float for two or three days. If the water inside and outside the bucket has gone down the same amount, your pool is losing water due to evaporation. However, if the pool water level has gone down more than the water inside the bucket, your pool has a leak. That's your cue to call a professional to have it patched.
