The 1.5 HP Waterway Executive 48F #3420620-1A is a durable high performance pump that delivers reliable water flow efficiently. Always select a replacement pump with the same part number as the Waterway part number.
Purchased this pump to replace existing pump.. same model.. first pump lasted 8 years with no issues..hope this is as reliable!
Pump description should say that the wet end is a 48F/56 so bigger than a 48F. This is not a direct swap and will require pipe changes if your hot tub has hard plumbing.
