I ordered a Hayward motor SPX1615Z1M. They sent an 'equivalent' Century motor instead. Did not tell me they were replacing it with something else. I tried to be flexible since it was the same HP and it fit. Now it has burned out 2 years later and I am stuck. I take great care of my system and this is BS that a motor that should last more than 7 years has stopped working after such a short time. I run my system less than 5 hours a day so it is not like it was running all the time. I paid for a known good quality motor. I tried to be reasonable and not complain. BIG MISTAKE. Now I am stuck having to buy another motor. Def not buying from this place.
