Hello Folks    Have a 2008 Tiara 3900 Sovran     The sump  ( shower and AC condensate )  pump  dumps into a collector mounted behind the cockpit fridge.  The unit looks to be unpowered with a round sealed  canister about 8" diameter and 12" tall..    

My problem is the sump pump will occasional backup and I find there is a intermittent blockage in the line running into the collector.  

I have blown it out, back flushed it,  even pressed a house to it.  My next move will be to fill it with Barnacle Buster.       Does anyone know a part number or manufacturer  of this collectors?     I'd like to determine what its made of and determine if there is a backflow preventer that may need to be replaced.      THANKS,  Vince
