Sales has some bad things to say about the Laing AutoCirc Pump. They go further with the comment, "We have also found Laing Thermotech to be an extremely difficult company to work with, and have discontined their entire mix of product from our offering." Would like to know if anyone can comment on their experiences with Laing recirculating pumps.
