You need a separate sump with its own pump
Ben: I have the same problem on my 87H285. What I'm now looking into is installing a sump box inside of the bilge pit where the shower and ice box now drain. This pit is big enough to accomodate a separate box of about 5"x5" x4 1/2" deep.The idea is that sump box be forward and above the main bilge pump. The drain hoses would be extended directly into the sump box, and it would have its own bilge pump. Because a bilge pump can never get all the water out, it would then be the sump box that would always be wet, which should leave the main bilge try.I'm just now starting to look around for an aftermarket shower sump that would fit in there. If I'm successful, I'll post the particulars on the 28.5 forum.Let me know if you have any better ideas.Eric LorgusS/V Explorer
