Great price and a hard to find size at 1/2 hp. Other people mentioned that the fittings on the inlet and outlet are metric and needed adapting. I have no idea how they are doing this since there are no fittings available that I could find that fit. I ended up having to glue a 1 1/2 coupler sawn in half onto the end of a pipe then turn it on a lathe to 1.985” The size of the inside of the pump swivel fitting. PVC pipe in 1 1/2” is 1.9”. Way too small. Anyway it’s done and good but yes be prepared for that inconvenience. I’ll review the pump further after I run it this weekend it’s for a hot tub at our beach house and we go there tonight.
