Will this 5.5 GPM pump fit and replace the original 4.0 GPM. Pump on NorthStar Portable Soft Wash and Disinfectant System 4.0 GPM Bleach Pump, Model #157140
1 answer-
NorthstarExpert12· 2 years ago
Using this pump in place of the 4.0 GPM pump on item 157140 is not recommended because it has not been through testing. The appropriate replacement pump would be item 157147.
