Hello:

Our air conditioning water intake needs to be bled every time that the boat heels and the lines lose their water. Closing the intake valves help but is a pain in the ****.

Any suggestions on how to help avoid this?

Are there A/C self-priming pumps worth looking at?

The problem with self priming pumps is that they are not rated for the continuous operation that the AC system requires. I had a similar problem on my last boat. I finally put a squeeze bulb pump in the input line, a couple of squeezes would reprime the pump without disconnecting lines.

On that boat, the installer put the thru hull where it was convenient, not at the deepest location possible. I made sure that did not happen on my current boat.

If you have a big unity, the bulb might pose some flow restriction. We installed a Y valve at water exit, and ran some lenght of transparent hose with a bulb. Turn the valve then squeeze (or suck) until you see the water coming. Well, still a pain but worked well ....

Herb - That is an AWESOME idea!

We have the same problem, but I found that if I shut the intake seacock, I retain the prime. While the A/C is running, I loop the engine key on the seacock handle so that I don't drive the boat away wihout shutting the seacock (I lose the prime when the boat moves and the valve is open).

Every now and then, I lose the prime even with the seacock shut, so the squeeze bulb is a great idea.

Thanks...... I love SailNet.
