I had this Pentair Master Temp 400 model brand new and paid about $3000 thru a pool repair company, it started leaking within few months, I was thinking it maybe installer did bad job to connect it, but it was leaking at heater blower inside the unit, discussed it with Pentair since it is within two years warranty, and they claim it was imbalance pool water chemical, they refused to repair it or compensate me, wow I had my old unit (different brand) for 15 years, it never leak water, I was using same pool company to maintain the pool, I have to replace older one because the burner no longer works, also the unit's outer covers are all plastic, my older unit is made with galvanized steel cover. So be careful when you buy this Pentair brand and model!
