I've read the posts about how some of you have plugged the icebox and instead you use it for dry storage. If you still use your icebox to store cold drinks pleas chime in. I would like to know if anyone has replaced the back flow preventer.

Thanks.

One time the through-hull there got clogged and the water from our sink started backing up into our ice box. Does that mean we don't have a back flow preventer?

Mine does not have a back flow/non return valve. If I forget to close the thru-hull valve I can get lake water in the cold storage while sailing. Defender has a check valves for hose if you want to install one. http://search.defender.com/?expression=check+valve&x=9&y=11

I removed the non-working back flow preventer and installed a ball valve in its place. I don't use the box for cold storage, but, if I should need to drain any liquid out, I can just open the valve.

I did the same as Davy.

I don't think that there is enough pressure to make a backflow preventer work well in this application.

I agree, The water draining out of the box isn't going to overcome the spring loaded ball. You won't get sea water coming up into the box but it won't drain ether.You need a check valve that works like a float without a spring and mounted vertically above the waterline. I plugged the drain hole and use the box for soda bottles and dry items but someday I will get around to taking that check valve apart and seeing what makes it tick, Might just need a good cleaning to get it to work properly.

My valve works... I filled the icebox with water and it all slowly drained.
I will try to actually use it this coming weekend now that I cleaned it.
I look forward to reading more replies...

Eddy my valve drained also but it also let sea water into the box if you are healing to the port side.

My problem with the back flow preventer wasn't seawater, because I normally close the seacock while moving. The annoying problem was dirty dish water from the sink would back flow into the box. ball valve fixed that problem.

I took my non-functioning backflow preventer apart and found the remains of what was probably a flap valve. I now use a lever action drain plug (like a smaller transom plug, available at any hardware store) and remove it when I want to drain the cooler. Not having a steady drain of cold air and water out the bottom of the cooler improves efficiency. It isn't as good as a quality cooler, but I'm up to 3-4 days on block ice when I start with cold drinks. If I start with warm drinks, I dump in a small bag of cubes to quickly chill them and then drain the cooler.

dave, did you insulate around the cooler? I was thinking of doing just that, and I have to make or find a lid too.

The C-25 galley is short enough on storage space that we found it useful to convert the cooler to dry storage and use an external cooler for cold storage. I found a tray at "Storables" (a storage items chain store) that could fit on the lip halfway up the cooler. That gave us a lot more storage and is a good place for fast grab items.

For our cooler we got a 5-day Coleman, I think it was the 52qt model without wheels. It lives at the front of the quarterberth and could be slid up onto the starboard settee when you needed to get into the quarterberth. That cooler worked great, in August I kept it full of food for 12 days and only added 14lbs of ice once (we started with 35lbs of ice). If I were doing it again I might get a smaller Coleman, but not much smaller. The reviews on Amazon for this cooler are accurate, the handles pop off too easily (they also go back on easily) but it stays cold for a long time. We didn't get the white marine model, it seemed to be more money for no additional insulation or featuers.

Our new Pearson 28-2 has a considerably larger galley and there are two storage boxes in the galley, one as a cooler and one as a dry goods storage. An interesting thing is that the built in cooler on the P28-2 has no drain, probably to avoid the issue of sea water getting back up into it. There we will have the annoyance of pumping it out to empty it.

My cooler is insulated on 3 sides. I will finish the 4th and bottom this winter. We use a small cooler with cube ice for drinks so they are more accessible and colder and replenish it from the built in cooler. On day sails we skip the portable and just throw a bag of ice in the built in so we have less junk aboard.

These are the two lines coming from the sink and icebox.
The line closest to the camera is from the sink.

I replaced the original back-flow preventer with an in-line check valve from WM with only a circular raised ridge on each end. I used two worm clamps on each end and it still leaked. You really want to get the in-line valve with the barbed fittings on each end and have the clamps at 180 degrees apart. Better yet, get the check valve with the clean-out trap. I use the cooler for dry and wet storage. I found that one bag of ice would melt in about 6 hours while 3 bags of ice would last for over two full days(I plan to add extra insulation over the winter). It's nice to be able to drain such a deep storage compartment by just opening the seacock while keeping grey or seawater out.

i removed the icebox drain, plugged the icebox with epoxy and i just have the sink going straight to the trough-hull... last summer i had lake water getting in the icebox and messing the food even with the back flow preventer :-/

i still use it as an icebox, i just keep 2L bottled of water in the freezer at home and when i go to the boat i take 2 or 3 depending on how long i plan to stay, the good thing is that when the ice melts you end up with drinking water! ;-) and when i leave the boat for the week i just wipe the humidity from the sides and that's it

We don't have a back-flow preventer, but instead use an adjustable plug to prevent seawater from backwashing into the ice box. When we are done, at the dock for the evening, we remove and simply let the water drain.

Depends on what I'm cooling.
For dry goods (fruit, meats, cheeses, dairy, eggs), I don't put ice directly in the cooler. I always place it inside a sealed tupperware container so that it cools the contents but does not soak them. Finding just the right size tupperware can be a challenge.
I also have a theory that ice should be placed above the items to be cooled, since cold, like water, doesn't run uphill. I usually fill the dry contents about 1/2-way up inside the cooler, then place a thin piece of plywood over the top. I then place the tupperware container on top of the board and this chills the contents. Everything stays dry.
My only exception to this rule is when I put sealed bottles or cans of soda, juice or adult beverages directly into the cooler, then I fill it with ice. Direct contact works best provided you don't have to worry about your stuff getting wet.
I did seal the galley cooler drain with a wooden plug to avoid the backflow unpleasantness. If I do fill the cooler with ice, end of trip I have to bail out the cooler since the wood swells up in the drain hole and becomes nearly impossible to remove.

It works better on boats because it's white and has "Marine" stamped on it.

I gave the backflow valve a good cleaning. Took it off and took it apart. It was full of all manner of gunk. Works fine.

I used the cooler last week (for the first time) and found that my bilge pump acts as the drain for this. It appears sink drain line was replaced and PO didn't "T" in the cooler drain line, it just flows into the bilge. I may or may not do anything to remedy this situation at the moment.

That seems like a decent solution actually. You wouldn't get any backflow from the sink drain or seawater while you're heeled and if your boat is dry, the melting ice water would probably evaporate (depending on your local weather).

My galley sink is completely inoperable at this point. Pump handle doesn't work and the drain leaks into the drawer. It's a great place to keep my phone, handheld GPS, keys and beverages however.
