Re: Diaphragm Bilge Pump failure.

Duane Siegfri

If you replaced AMFA Bilge Pump with a Johnson Viking Power 32, how did you connect the 1.5" hose connections to the 30mm hose on the Amel SM?  

It would seem easy enough to replace the 30mm hose with 1.5" diameter, but where the outlet hooks up to the main line going overboard, there is a fitting with a total of three lines coming in and one going out.  I wouldn't want to replace that...

I checked with the manufacturer, the hose barbs are molded into the pump body and cannot be replaced.  So it seems the best thing to do would be to:

1. replace the 30mm hose that goes into the sump with 1.5" diameter hose with a new check valve at the bottom.

2. find a 1.5" diameter to 1.25" diameter hose barb adapter to connect the outlet to the old hose.  I have not been successful in finding one of these.  If this is what you did can you tell me where to look for one?

Thanks for your help,
