I am replacing an intex pump with a hayward pump to go with my sand filter. The fittings adaptors that I purchased work perfectly, but I am wondering about the electrical part. There is a grounding lug on the side and it has a three prong plug. Am I okay to just plug it into a gfci? My intex was plugged into gfci, but it also had its own reset botton on the end it the cord. Also the cord is only 6ft long and the instructions say to not use and extension cord.
