Our pump for the spa jets needs to be replaced and I have received a quote for $4k from our pool company. First, does the regulation for variable speed pumps apply to a pump for intermittent on demand jets in the spa - not the filter pump? I do not read it that way. The cost of motors for a 2HP pump is around $600. I am sure there are other parts that need to be replaced with a new motor, but can anyone tell me why an estimate woud be as high as $4k? What am I missing here?
