Rule Bilge Pumps; Defective Plastic?

Rule Bilge Pumps; Defective Plastic?

Post by Mike Lowi » Fri, 05 May 1995 04:00:00


I am in my second season of replacing defective plastic parts on a Rule
model 1500 bilge pump.  The plastic in the pump base becomes brittle and
then quickly fails (2-3 months).  Examination of the broken parts reveals
embrittlement, and cracks.  Last year Rule customer service and their
engineering department emphatically denied that there was any problem
with platicizer leaching out of any of their plastic parts.  I replaced
two pump bases and a model 1500 pump.  (By the way, my bilge is now and
has always been dry and clean but the boat stays in fresh water).  This
season, after getting used to checking for pump damage I discover yet
another disintigrating strainer base.  I contacted my OEM boat
manufacturer (not Bayliner), and they were not aware of any problems.  
When I contacted Rule today, it seems that other boaters are having this
problem and Rule will gladly pay shipping of replacement parts if I ship
them my bad parts so they can continue "looking into the problem."  The
purpose of this posting is two fold:  First, if you have a Rule pump as
large as a model 1500, make sure that it is not flopping around in your
bilge and not damaged internally as I found on the OEM installation.  
Second, Rule is very slow to acknowledge that someone they subcontracted
plastic parts out to had a bad batch of parts and should make it right
for everyone who may be relying on a defective pump.  I am not interested
in a fire storm but am interested on what other boaters find when they
look in their bilge.  Any good plastics engineers have a guess why this
is happening?  (The pump is not mounted so that it could bounce around).

Good gasoline fumes be the cause of your problem?

We have had similiar experiences with Rule float switches.  We had two
fail after only a year of operation.  Both had small cracks and were full
of water.  We "switched" to a West Marine Product.  OK so far.

Any others with similar experiences??
