One often hears that cruising is "fixing your boat in exotic locations." Exotic or not, repairs must be made, and making them in a foreign land and foreign language can be frustrating. Or not ! Here is a feel-good story about a simple and cheap fix to a big problem.
The
pump : Jabsco Par-Max 3.5 fresh water pump (frankly, the
following information will apply to any pump).
Important
clue : installed on new boat (or boat with new tanks)
Symptoms :
After 15 months of loyal service, our water pressure began to
decrease. For the first few seconds, the pressure was good, then the
flow would slow to a trickle. Even after the tap was turned off, the pump
laboured to reach it’s cut off pressure.
And
yes, we regularly clean our filter.
Diagnosis :
We were lucky enough to be in Pollensa, Majorca (reasonably exotic), berthed just across
the street from Astilleros Cabanellas, and had a 2nd stroke of luck
to have Senior Cabanellas himself (grandson of the founder) take a
look at our problem early one morning. He spoke perfect french and, although we didn’t
test him, probably speaks pretty good English, too. If you are planning to
have problems in Majorca, have them here.
He had seen the problem
before… especially on new boats. The
problem is a blockage in the in-line check valve located upstream of
the filter (red arrow in photo below). When the tanks were fixed in the boat and holes drilled
into the plastic reservoirs to attach fittings and gauges, the
technicians failed to vacuum out the little shavings left behind.
Over time, these made their way through the system and got stopped
here.
Senior
Cabanellas knew exactly where to look, and sure enough, we had a big
plastic ball of bits there. He shook his head and said that many
shipyards will simply tell you that your pump is going bad and that
it needs to be changed. In changing the pump, they open up and clean
out the surrounding fittings, so it appears that the problem has been
resolved with a new pump when in fact the pump was fine all along.
With
the blockage removed and the accumulator tank pressure topped off
with our bicycle foot pump, we reprimed the system to chase out the
air bubbles and the pressure was as good as new. The pump now runs
beautifully, only turning on and staying on half the time it did
with the blockage, so we are saving on battery
energy as well.
We
contacted our Jeanneau boatyard in France to let them know that this
was a problem somewhere along their assembly line. They thanked us
for the information and are reimbursing our costs. (When we bought
our boat, we were told that the 2-year guarantee and the Jeanneau
service-after-sales were excellent. Now after 2 years we can tell you
it is TRUE!)
Problem
resolved in 30 minutes, cost 35 Euros. Happy ending.
