Just got a free leisure bay 4-5 person tub and ran my 240 power and quick fill plumbing. I replaced the pump attached to the main jets, now trying to find out which 240 pump they use for circulation off the heater. just the 2 pumps and apparently no circulation pump. It has 2 caps on the pump and no plate, just a sticker that says 4.0 hp spl. so any single speed 4.0 hp pump with correct plumbing connectors will work? Will attach a photo of layout later because I cant seem to identify actual model. It has an old balboa vs249r control system I seem to have working, just need to replace the 30A fuse on the board AFTER I replace the bad second motor. The first motor was a lingxiao Model: 56WUA400-II if that helps.
