Galley sink drain hose

Do you know how some projects lead to others? This past weekend I was replacing my water heater and decided to relocate the fresh water manifold to under the sink as others have done. I was messing lightly with the galley sink drain hose when it cracked in my hand.....my hoses are 18 years old, but I would recommend inspecting and replacing if you have the crap%^ type of ribbed style "bilge hose" for your galley drain. It is NOT the proper hose when connecting to a thru hull. CY may have changed this with newer production models. I replaced it with 1" reinforced vinyl hose and all is well.

This opened my eyes regarding closing thru holes when off the boat.

My 1999 model has high quality reinforced hoses. I can't say if they are original, but I bought the boat 5 years old and it appears likely.

Good thing you caught your problem in time.

I wouldn't use that plastic hose anywhere below the water line. OK for bilge pumps and whatnot, but I can't imagine any builder using it below the water line. Perhaps a PO?? I think I'd check some of your other lines as well.

I always close the through hulls when leaving the boat; helps me sleep at night:)

Interestingly, I have hull number 1469 so not so much later in production than yours. I had to pull off the sink drain hoses last week to clear a clog in the thru hull. The hoses seemed to be in fine shape, strong, and reinforced as described by others. Your post will lead me to look again but I am reasonably sure that all is well with the hoses. I did replace the hose clamps. BTW, I paid the marina to replace my hot water heater this season and the cost for labor and the heater was around a boat buck, $1K. The price included replacing all of the hoses to and from the hot water heater and from the fresh water manifold. So, good that you did it yourself!

I think it was original hose....I am trying to post a picture, but having trouble with that.

1494 had that junk hose on it as well, I replaced it the first year we had the boat.

Just replaced ours on our '98. It was wire reinforced. I used straight 1" hose as there was no reason for the wire reinforcement as it is simply a drain hose and not under suction.

Good point, David. I may have misspoken when I said 'reinforced.' I really meant it was a high quality, heavy walled hose and not some flimsy stuff.

Shields 162 or 164 hose meets the requirements. I got 50 feet of 1/2" hose from go2Marine (online) for $36.

How difficult of a project is it to get the old hose off the galley sink and thru hull? I am almost positive I have the bilge hose used. The refrigerator drain hose is also "T" off the drain hose. The boat was only five years old when I bought so Catalina had to have installed it. The hose actually looks to be ok and is double clamped, but even West Marine cautions against using it below the water line or on thru hulls.
Thanks to the forum for raising this caution flag..

My decision to replace the sink thru hull hose was based solely on the observation that the hose had evidence of cracking along the reinforcement. It was 14+ years old. Since I was replacing it, I replaced all of the other hoses under the sink. Not all that difficult with the challenge being the breaking the main hose loose from its fittings. As I said previously, there is no need to use wire reinforced hose for a drain.

I just did that on our boat, including the hoses to our head sink.

The trick, since you're going to throw the old hose out anyway, is to use a box cutter and simply slice lengthwise at the end of the hose on barb, then, if necessary, use a flat blade large screwdriver and work it off.

We discovered last week that we also had bilge hose as a drain hose for the galley sink.  It broke while we were moving it out of the way while removing that cabinet to replace the water heater.  What we discovered when we went to replace the hose with proper drain hose was that it appears that someone had shaved (maybe dremeled) the barbs off of the connector on the thru-hull.  We would be very disappointed if this is how it came from Catalina.  Just curious if anyone else has come across this?  We have hull number 1388 which is a 1995 MKII.

Never seen that on our boat.  Looks like you could replace the tailpiece with a new one (with barbs!) without removing the seacock, however..
