T&T: A/C Pump Problems

[Ken Ongemach]

Yep, the pump is not the problem...U have a cooling line full of marine goop..
I just went thru the same thing on a friends boat... Find an external pump,
disconnect the cooling line at the output of the strainer & at the output of
he 1st unit put a bucket there, then hook up the pump & pump Muratic acid thru
the hose &  the 1st unit until it comer out at full flow, then reconnect &
move to the 2nd unit, etc....eventually U will get a black gook out & the
cooling line will clear...Running 4 units off the same pump in Florida warm
water is almost unheard of, from the same cooling pump.. When U get all the
goop out, reconnect the pump & put a scrap piece of copper tubing in the
basket & leave it... U will not have the problem gain due to marine growth,
due to the ion exchange of the copper into the salt water.. The crawlees till
not stick in the line...An old Florida trick...Ken, Tampa, FL
