This weekend our Rule automatic float switch died. The one we have in there is the original (2001 Catalina Hull 62). There is no identifying model numbers on it, so I can't provide that to you. Anyway, it is a shorter float that what is available now on the market by Rule. The ones on the market by Rule are around 5" and I can only use a 4 3/4" float. Our pump is still good. I've been looking around and I see there is a Water Witch electronic bilge switch which is relatively small and should fit between the keel bolts. I'm wondering if anyone has used this as a replacement or has any reviews on it.
