Hi All,
I had the same issue - twice. The first time Leslie Pool Supply replaced the entire pump under warranty. Last month (8 months after the last replacement) I had the same issue. Leaking from the pump housing (part # R0723100). This time Leslie said they could not help and could not get the part. I called Polaris, explained that I’ve had the same issue twice in less that 20 months. They advised that the part has been redesigned and agreed to send me the new part. I’ve now received the new pump housing and it is installed. I’ve included a few pictures of the old part showing the crack and side by side of the old and new parts. You can see the added reinforcement on the underside and inside around the inlet.
Best regards
Tony
