Another Slurpee Installation

  Nellie D. 37VT63's wet bilges have driven me crazy.  Today I solved the problem by installing a Slurpee  What's a Slurpee?  Here's a previous post that discuss the Slurpee's design details and here's a post that discusses the Slurpee installation on Knock Off 37VT66.
The 3.5 gallon/minute Shurflo pump is mounted under the floorboard just outside the head.  The pump's mount is made of high density polyethylene (HDPE) cut from a 3/8" thick, $9, Wal Mart, cutting board.   The right angle in the HDPE was formed using a heat gun.  
Two 1" PVC threaded nipples were screwed onto the Shurflo's 1/2" MIP treads.  Then the 1/2" MIP end, of a 1/4" hose fitting, was screwed into the bushing. 
The effluent is pumped into the drain line of the head's sink.  To accomplish this the opposing ends of a 1" PVC tee were hose clamped into the cut drain line.  After a bushing (1" slip  to 1/2" FIP) was glued into the tee, the 1/2" MIP end, of a 1/4" hose fitting, was screwed into the bushing. 
The programmable controller, with manual on/off switch, is mounted with HDPE under the galley's floorboard.  Visible just to the right of the controller is a vacuum line connector.  It's here that either the forward or aft bilge pickup is plugged in.  
Nellie has two strum boxes: above is the picture of the under-engine bilge strum box.  The strum box in the aft bilge is all the way back under the stern tube.  Notice how dry the bilge is?  Ahh.
