Very affordable 2hp pool circulating pump. Arrived well-packaged ahead of schedule, with all accessories and a user manual. 220 V electrical hookup was simple with clear directions provided. My suggestions on including a wiring diagram of the 120-240 volt switch were sent to seller, as I initially had electrical hookup questions which seller promptly responded with a picture and perfect guidance. This motor is very quiet and seems much more more powerful than my old 1hp Hayward pump, which died after 8 years. The inluded 1 1/2” plumbing adapters fit my American PVC pipes perfectly. In fact the seller happily provided me 2 extra 1 1/2 “ adapters for free on request. This Chinese pump seems high quality, does not leak, is very quiet, and seems quite powerful at 1/2 to 1/4th the price of a high end American circulation pump. An excellent deal.Addendum: While this powerful pump worked perfectly in circulation mode, in vacuum mode its strong vacuum caused water trap cavitation and priming loss when used with my underground pool’s small (1 1/2”) diameter plumbing system. This was not due to any leakage or fault in the pump. The supplier kindly (and immediately) helped me diagnose this problem and then resolve it completely by accepting prompt return of my SINGLE speed, dual VOLTAGE model, with replacement by their identical, dual SPEED model. The dual speed replacement pump can be used in vacuum mode at the slower speed with no loss of priming.Overall, this a superb, powerful pump, and its suppliers were invaluable with their immediate and kind support and assistance. .
