Hi all,
for the first time in our 14 years ownership I have an aircon problem. The units all run, I have checked that the cooling pump runs and delivers good water flow but the water circuit is blocked. ie no water coming out of the exit to sea, port side forward. Having completed the above checks I am about to start the search for the blockage. Because there is nil flow barnacle buster is not an option. I would appreciate any experiences anyone can share.
Kind regards

Hi again, one more thing I tried was using the deck wash pump to put back flow pressure from the outlet to sea with the pipe disconnected from the aircon pump. Nil flow

Danny,
I would get my hands on any acid available and dilute it down to barnacle buster strength. The hoses are so long and the clog could be in one of the units.

Danny,
Do you have the
option of connecting a water hose (connected to a shore facet)
in the beginning of the run near the AC water pump? This would
possibly give you more pressure.
The next thing would
be to start with the forward unit and working your way back
and check for blockage. Use a hose with some pressure, connect
it to the "in" on each AC unit and see if you get flow at the
seawater through-hull outlet. Once you have isolated the area
of the clog, you can better address it. Or, perhaps you could
use compressed air (I've never tried this).
BTW - Barnacle Buster
is just 15% phosphoric acid. Save yourself a fortune and just
buy phosphoric acid in the paint department of any hardware
shop.
With best regards,
Mark

Thanks Jason, but as I said in my post, without water flow I cant get barnacle buster into the system.

Is it possible the valve inside the hull near the water exit port is closed.
Sometimes a 2 meter piece of about 7mm rigging wire is useful to run through the bitter ends of that water circuit.

Hi Mark, thanks for the suggestions. My deck wash pump is a jabsco parmax 4 with 40psi and I have tried that both ways, from the inlet and the from outlet and there is not a trickle coming out. I have considered compressed air, I have a method of using my dive reg on a bottle, but a bit nervous about blowing something up.
Yes, the progressive detachment and check is my next step.
Barnacle buster, again, no water flow so cant get that in.
I am puzzled that after all these years it suddenly stops, but that's boats I guess.
I have just returned from a visit to the South Island of NZ and the Marlborough sounds so I have been in different water.
However while I was there I didnt use the air con, and there is no growth in the system from the through hull to to and through the pump. As Alice said "curiouser and curiouser" ( Alice in Wonderland)
Kind Regards

Hi Bill, thanks for this idea. Is there a stop cock in the water line about a meter from the outlet. I pushed a length of plastic tubing up and came to a sudden stop. Cant imagine how it could have turned itself off though. As I said to Mark my next step is to go along the water line checking. The forward unit was not going and I found an electric plug had come out, bumped by a bit of something in the boisterous sail back from Marlborough Sounds, but I cant see a water valve being moved like that. But I will look. The sudden non functioning warrants looking for the bizarre.
Kind Regards
Danny

Lift up the port side V Berth bunk. You will see the valve and the AC unit. The water jacket on the AC unit is what you hit

Thanks Bill.. Pretty obvious that I have not had a need to look for it. A glance would have done it. Anyway thanks Jason, Mark and Bill for your input. Problem solved. The 500 mile boisterous sail, some on the wind, back from the Sputh Island caused the forward unit to move, pulling the elec tric plug and kinking the water hose. Wish all my problems were so simple. As I said the bizarre was likely.
Kind Revards
