there was a thread not long ago about rust in AC pan and using a pump to keep it dry. The Mermaid pump is quite expensive. I just noticed it is on sale now for half price at Defender, http://www.defender.com/product.jsp?path=-1|6880|48359|328481&id=162519&cartId=3733640

Yes

I also saw that I think on Amozon,does it get hook into the pump overboard outward and small line to the pan and sucks the pan water out I guess and really like will order one for sure. great price

Coolair

I am guessing that is from your AC and the venturi gets hooked to the AC pump before or after the pump,hard to see what you have there with the shut off values.
That is on my list when I return to Florida and we leaving NY today heading home finally.

Robert, if my boat were to sink, the cause was not easy to determine and I had installed one of the devices on my vessel would my insurance company try to use it as an excuse to not pay the claim ? I don't know.

I always think about that when I change or add something to the boat. I have never had an insurance claim so I have no idea how closely they investigate these situations. I suppose if I run my boat on to the rocks through my own negligence they would pay so maybe if I modify the boat and that causes it to sink they would also pay ?? I don't know if it would be good to ask them how this works or not ?

At this point the difference is $60, and it comes with a check valve, the hose, and piece of mind, so it is worth it to me .

fair winds, Bob

Bob ....I understand your reservations...
These two a/c discharges are above the water line and attached in a protected location behind the salloon cushions. The only time they go under water is when I am sailing. And only go under when at about 5 knot on that tack. They have been operating this way for the last 7 years with no problems. These seacock valves you see I have been using in various other situations for many years and they have proven to be much more reliable then the 400 percent marine markup metal valves. The ones that were first installed on this boat all failed with in the first year. These valves you see I found at home depot about 12 years ago, Not one has ever corrodied,cracked,jammed or failed to do their job in any way.
Now if you are not comfortable with this location for the a/c raw water discharges Then a more Ideal location for discharges would be to move them to the location of the main bilge pump discharges which on my boat are at the stern on the port and starboard sides. In this location the thru hull discharges never go under water.
Btw.....In fact hopefully one of my winter projects that I would like to do is to move one of the two a/c units located under the saloon cushions. One is the original factory location that was ducted to a/c whole boat. The second smaller unit next to it is ducted to rear cabin the 2nd raw water discharge was place there strickly out of convenience. I hope to move this unit to the rear cabin were both raw water fittings will then discharge at the stern next to the existing bildge discharge locations. My plan is make other improvement with the way the a/c raw water pumps are mounted and the way plumping is set up. I have never really been satisfied with the setup I have now. Factory or otherwise. I now have a plan to fine tune and make things much more efficient then the way things are now. Just need to wait for cooler weather.
thanks

I plumbed all 3 of my airco units to a shower dump box in the bilge. Works perfectly. Not a drop of water in the bilge.
Just have to make sure that the box is lower than the airco pan, and all runs are downhill,
Tfe output of the sump box goes overboard way above waterline.
So, this costs one sumo box, bunch of hide.
It is a 10-beer project timewise

I tried it that way....Did not work. Just wore out Shower Sump Pump. Then the sump box would run over and then it wore out Bilge pump! With the 20 dollar Venturi's......Well as "Marvin" would say no more slime in the ice Machine!

I just installed the $20 venturi and creates plenty of vacuum. It does reduce the water flow and I am concerned if it is going to over burden the water pump. I wonder also if the reduced water flow will diminish the cooling effect on the condenser.

One thing I hadn't considered is that my condensation pan is below the water pan. I had to purchase a check valve (usplastics had a nice brass one).

Purchases HD for adapters, clamps, the check valve and shipping, and the venturi purchase this 1/2 off special is the way to go.

onecoolair · Sep 18, 2012

attach venturi directly to the above the waterline discharge

That is interesting....My discharge stream did not seem to change that much. The stream just changed to a frothy white once the venturi had sucked the pan dry.
Questions .... Did you attach the venturi directly to the above the water line discharge seacock valve and then the discharge hose to venturi? Also what type of raw water pump do you have? That could be your problem.
... I use the more powerful and reliable little giant raw water pumps. The original that was installed new at the hunter factory back in 2002 it is a 4-mdqx-sc little giant it is still being used for the newer 16,500btu mermaid, this same pump is still functioning perfectly after 10 years. The cruise air died after 4 years but the pump lives on!...The two other raw water pumps are 3-mdqx-sc little giants and are being used with the two 5200btu mermaid units. (see pics below)

Onecoolair- I didn't pout the venturi directly on the seacock- instead its inline of the hose that runs from the ac unit to the discharge. It is above the waterline. I does create good suction- it pump out a tall glass of water in about 10 seconds. Your probably correct about the pump. I don't recall which one my mechanic installed but I do remember he said he didn't purchase the pump from mermaid.

I'm sure my new install will work just fine, but at half price, I purchased the kit from mermaid just for insurance. I feel a little more comfortable using the manufacter's approved system, if for no other reason to CMA.

I also tried the mermaid venturi. Had it installed in line just above a/c unit and only 1 to 2 inches above water line. It seemed to work for the first 8 months or so till there check valve malfunctoned. Good thing I was there when it happened. Otherwise my boat would have sunk. The thing back siphion and started filling up bildge. Removed the mermaid valve and fancy verturi to clean it. And it exploded in my hands. Small bebes and springs and some other small mystery dodads shot of somewhere in all directions???
That was a total 250 dollar ripoff as far as I am concern. Mentioned what happened next day to a neighbor . And he showed me what he had done.
As it turned out the new venturi I found at the saltwater aquarium store had male and female ends which matched up perfectly (even the proper direction) with the seacock valve I was using and the fitting on the discharge hose that was screwd into it. "See pictures previous post". I have not had any problems since. And no check valve has been needed.
BTW....I would recommend sending the unused mermaid venturi back.
What would be nice is if Marlon or someone would make this simple designed venturi in a higher grade plastic composite or anti corrosive metal . Now that would really be a home run. But so far this "simple" plastic venturi has proven to be very reliable and maintenance free. As well as the red handled resin ball valves I found at home depot that I have been using as replacement seacocks for the last 8 years with not one single failure or need of replacement.
