So our Hayward 150FDN made it almost 4 yrs to the day before it started leaking the other day. Opened it up and it's def seen better days. Rusted all over and leaking in multiple spots. I maintain the chemicals and quality of the pool second to non. Also help 2 other people with the salt water pools. Neither of them have heater problems either. 1 has a 4 yr old unit also and another has 1 going on 8 yrs. please tell me some better brands as I would have though an $1800 heater would def last longer. Looking for internals more suited for salt.
Thanks in advance, Jeff
