T&T: Aqua Whisper Watermaker Boost Pump

[Pascal Gademer]

arent' you supposed to G'Day  MATE? :-)

The booster pump is nothing more than a low pressure pump, identical to an 
air con pump, there is no way that should cost $2500 to replace!!   It 
shoudlnt' rust out in so little time, if it does you have another issue to 
deal with like salt water spraying somewhere.

check the flow specs on the pump and match that with something else.  i'd 
guess that for a 350GPD WM you probably need about 1000GPH flow total?

there is a large pump distributor in SW florida, very well know, that 
carries just about any kind of pump and motor. unfortunately i cna't 
remember the name, but i'm sure someone will know...

 good source of pumps is http://www.oberdorfer-pumps.com/ too, see what they 
have.  they are supposed to be very good pumps and motors.

If you do run the watermaker in the ICW on the loop, make sure you pack a 
good supply of filters!!!  you will get a few hours at best out of the 
smaller 5 and 25 microns prefilters.  if the WM has not been used in a while 
it may require some maintenance... check all the filter and replace, you 
should also have some charcoal filters in there.  a good source of filters 
(fraction of the cost) is www.filtersfast.com   that's where i roder mines.
