Title: IceBox Drainage
Post by: The Great Godsea on May 14, 2013, 12:45:22 PM
Newbie question. where does/how does the icebox drain? seems stopped up somewhere and i dont want to try to snake the drain for fear of tearing a line. i cant tell which of the various holes in the hull/bottom (or is it some other outlet?) the melting ice water drains to. Thanks in advance. Mark

The icebox drains into the shower sump, which is the small box that is visible under the floorboard hatch in front of the main table. This in turn is pumped out thru an above-the-waterline thru-hull via a pump that is activated by the manual switch in the head/shower area.  The thru-hull is located on the stbd forward area, accessible from the V-berth. In the original installation, it had a gate valve installed there.

When the shower sump fills up, water starts to back up into the icebox and the floor drain of the shower, under the teak grate. 

Some 323s have had the sump box removed, and allow the icebox and the shower to drain directly into the bilge.  This is a bad idea, as all the organic debris from the inevitable icebox spills, plus the shower and small sink output will quickly have the bilge smelling like an open sewer, especially in the hot summer months.

My icebox connects to a small "Jabsco" pump next to the sink.  A few strokes empties any water into the sink (and therefore overboard).

Thank you both for your responses. we tested all the pumps and bilges and outflows yesterday and i think we found all of these items... except a way to get water in the icebox to drain. there must be a blockage somewhere.

The icebox drain is a small line, so it's easy to believe it's clogged. 

The first thing you should try is to locate it and disconnect it at the shower sump box.  If it doesnt flow, it's clogged.  If it does, the obstruction is further downstream.

If it's clogged, try blowing backwards through the hose.  This may dislodge the clog.

The last resort is to replace the hose, but the icebox end is real hard to get to.  It can be accessed through the small storage cabinet under the stove area.

Do you have the sink pump or Ed's sump pump setup?

Mine was also blocked when I first got the boat...two problems.  First, a blockage: I used a wire as a "snake" to ensure the first few inches of the pipe were clear.  Second, my pump had lost it's suction; fortunately a repair kit was available online.

The other common problem I had is when a clear bit of plastic gets into the icebox, covering the drainage hole! Duh! Stumped me for a while why it would no longer pump out....

If you have the sump pump setup - Ed may chip in here - I am assuming the pump works fine and you have suction?  With my sump pump, if the plug is left out in the head sink, the shower won't drain - it just sucks air from the sink!  So a longshot, but is your plug in!!!  ;D

Interesting...

My pump has been replaced with a Jabsco self-priming pump, and seems to have plenty of suction, but not much volume.
When my shower started draining slowly, even with the pump on, I discovered a small in-line strainer near the sump box that was clogged with hair!  Don't know if it is OEM or added by a previous owner (there have been eight!).

Libations Too (hull 349) is set up with the ice box drain routed to a pump at the sink, much as described by Selene. Perhaps this arrangement is common in the later years of 323 production.

Personally, I would not want my ice box connected to my shower/lavatory sump or drain to the bilge without some type of back flow preventer.

i contacted the previous owner yesterday (great conversation) and he believes that the icebox drains directly into the bilge. so, i'll just spend some time this weekend hunting that tube down and clearing it. thanks again everyone for your input. can't believe how much i'm enjoying working on this boat. first boat i've ever owned. i'm even dreaming of it already and it isnt even out of drydock yet.

Slightly off-topic - hope you guys will forgive me - a little while I visited "Enchantress", which was for a while docked opposite me.  Nice boat, with many mods; one which particularly impressed me was converting the chart table so it pivoted upwards, opening up all that lovely space for storage (okay, that was a total digression).  Also (here is the relevant bit) the shower sump was moved forwards, under the space between the two access panels.  This not only made better use of otherwise unused space, but also opened up a big area forward of the bilge where the sump container used to be - still accessible under the main access panel - where he fitted a drop-in storage box.  Nice!  So if any of you guys are mucking around with that sump box, give that some thought....

and for my off-topic item... what have i done to get negative Karma? what does it mean?
Title: Re: IceBox Drainage
Post by: selene on May 17, 2013, 09:40:50 AM
This karma thing beats the heck out of me - I guess when people don't like what you say, they ding you.  If they find your comments valuable, the nudge you up.  What you could have possibly done to get dinged is beyond me - so I fixed it, as your questions seem reasonable!  Maybe somebody didn't like the fact the icebox drainage had been discussed briefly in an earlier thread?

Anyway, don't feel bad.  I personally don't like the negative Karma idea; I was also sent negative for a while, and remain unsure why.  Not a happy feeling; but as you have already seen, there are many good folk on this site who are willing to help a fellow 323 owner in any way they can!

The ice box drain on Now or Never! is plumbed through the foot pump that pumps sea water to the sink.  There is a Y valve that switches between sea water and ice box melt water.  It is important to have some kind of filter to keep ice bix debris from fouling the pump.  You can put an in-line filter for this.  A simpler solution is to roll up some screen wire and put it into the drain hole in the ice box.

Interesting...my footpump pumps freshwater to the sink, not saltwater.

My icebox drains into the shower grey water box under the center floorboard. It was always a mess with it's 30 or so screws holding the lid on. One of my first projects 13 years ago was to make a new grey water box from Tupperware. Make the icebox drain inlet high so shower water doesn't reach it. Make the shower drain and pump inlet low to keep grey water away from the icebox exhaust. One of the things my original owner left was a rubber drain plunger without a handle in the locker under the stove. It is to plunge the icebox drain. We sure have a huge icebox and it was one of the things that got my attention years ago.

Just how many cases of cans will fit in there???!!!

Here is my new shower/ice melt sump. I plumbed a piece of SCH 20 PVC to the original PAR pump and then with a pair of ball valves so I can choose to pump the sump or the bilge. For years I had a y-valve and garden hose adapters to do the same job but it no one could figure it out. This is pretty simple- S for sump and B for bilge.

The vertical PVC in the bilge is a brace to stabilize the cabin sole. It is made from light PVC and the second piece is slit to telescope over the first. That way the whole thing can be extended and holes drilled for fasteners to hold it tight against the bilge sump and underside of the sole. The top has a cut to accept the joint of the sole. It's impervious to bilge water.

After reading everyone's posts, I decided to attack this issue on my boat last weekend.  My boat has the silly, low volume Jabsco pump on the left side of the sink which always seemed to me to be mismatched to the size of the ice box itself.  Took me forever to pump the ice box one day.   As someone noted, getting to the hose under the icebox is a PITA, but accessing the hose from under the pump on the sink is quite easy.  The hose coming from the ice box and going to the pump is a 5/8 water hose like the rest of the original water hose on my boat.  I simply added a piece of 5/8 hose using a fitting and hose clamps, ran it forward and installed a fitting in my sump.  I had replaced the original sump with an Attwood sump system that contains a float-activated bilge pump, so no need to have to activate a separate switch to pump it out.  We loaded the box with ice on Sunday and so far, so good.  fwiw

I took a low tech approach. I have the pump that outputs the water to the sink. Most of the time I use the ice box for dry goods as we have both a fridge and separate Dometic freezer we use on shore power.

On the rare occasions we use the ice box for .....ice, we drain it with a dollar store super soaker tube. Pulls all the melt water in one pull rather than pumping that small manual pump.

Same here. Whale dual action foot pump for emergency freshwater from tank manifold... Separate PAR hand pump for salt water at galley sink.

As supplied by Pearson.

Resurrecting a dead thread! I had the old sink hand pump, replaced it with a small diaphragm pump.

Me too. Top valve between tank selector valves switches between electric water pressure pump and foot pump.
