Re: Water maker hose in the Bahamas

Pat,

I don’t have a specific answer for you, but if you are in Spanish Wells, you are surrounded by the Bahamas high seas lobster fishing fleet.  Every one of those boats has many hydraulic systems onboard. Just ask any of the locals, in our experience they are VERY helpful and friendly.  If they don’t know who does hydraulic repairs locally, they will point you to someone who does know.  I would very much expect a local can help, but the absolute WORST cast you’ll have to go to Freeport.

Hydraulic hoses suitable to replace your leaking HP hose are a very simple and inexpensive thing to source.  Having one shipped in will cost a mint.  

Before you have the hose replaced, be sure to examine the two fittings the hose connects to.  A common failure failure mode here is pitting corrosion of the mating surfaces of BOTH the hose and the fixed fitting.  If the fixed fitting is AT ALL corroded, scratched, cracked, or otherwise damaged it will need to be replaced as well from the same source.

If one hose has failed, it might be worth replacing the other one as well as a preventative matter.  

When installing the new fittings it is not good enough just get them “tight”. It is completely possible to over-tighten these and crack the sealing flare. Follow this procedure EXACTLY:

  1. Assemble the fittings. Using Loctite on the sealing surface (not the threads!) is helpful, but not absolutely required. You can always add it later if it can’t be found locally.
  2. Screw down the female nut until finger-tight. At this point the seat is making contact. You can double-check by trying to wiggle the tube portion of the female fitting. You should not be able to feel any movement. If there is movement, try tightening the nut again while wiggling the tube. If the nut won't turn any further by hand, and things are still moving, look for the reason why the nut stopped short. 
  3. Mark the fittings. Using a permanent marker, draw a line on one flat of the hex on the male fitting and a matching line on the female nut (the two lines should line up). This is your reference mark. 
  4. Tighten the fittings. Using two wrenches to avoid torquing the fixed fitting, tighten the female nut 1/4 turn, or 1.5 hex flats. Check your reference marks to be certain that the nut has been tightened 1/4 turn. STOP.  If it leaks when this tight something is wrong and more torque is rarely the answer.
