I have an AO Smith K48M2PApump that need to be replaced. I am told that I will need a variable speed pump which then requires me to replace the filter. Thus instead of costinf $300 to replace the pump , I'm being quoted $2300. I see that this motor is still being sold to people with addresses outside of California. As I read the law it just requires motors MADE in California to meet the new standards. If I get a motor sent to an addres outside of California, then sent to me, would there b any problem for a contractor to install it?
