That said, they appreciate the quality, performance, and noise level of the product.

Replaced its predecessor like magic minus a couple issues

Replaced its predecessor like magic minus a couple issues
Dear Vendor: Please provide the correct picture. Use mine if you have to.This pump was purchased to replace its 1999 vintage predecessor. It let off a burnt rubber smell and ceased functioning after 21 hard working years. The old product number was 59896163 (blue) and this is the 59896155 (red). The model numbers matched (UP15-42F) as did all of the other specifications. As you can see the original pump's housing has two small pipes connected to a pressure differential switch.The burnt out unit was removed. The opening was cleaned and the new pump fits perfectly.This is easily worth 5 stars, but I'm removing one because that picture is wrong. Also, the screws that hold the electrical cover to the body seemed too long for their holes and I ended up zip tying it.The fact the original blue portion could be leveraged saved a lot of gaskets, wrenches and headaches.
Thank you for your feedback
