Great product.
The larger Rule pumps seem to work longer than the smaller ones. I replaced a 10 yr old pump with this one. Easy swap using same strainer mounting.

Rule Pump
This pump is for a newer style shower box, I didn't realize that and had to return it, but Defender is easy to deal with when something has to be returned. Great service, thanks guys!!!

Easy to Replace Bilge Pump
This purchase was to replace the same brand and size existing bilge pump. It is nice that the wire colors have been kept the same and the pump base is the same. So, the new pump locks into the existing base and the same size hose slides right on. The previous bilge pump came with the boat, so I don't know how long it lasted.

I double dog dare you to locate a spec sheet for any rule pump other than the 1500. Searching on a 2000, 3700 or 4000 spec sheet takes you to the 1500. This will not help to identify discharge hose size.
Hello, Please see the attached image with the spec sheet.
