Works perfectly. The only interesting thing is sometimes the sink P-trap will get pulled dry after a long run but a little water down the sink and all back to normal. Maybe that happened when connected to the sump also....

Tom et al.,
I am embarking on my galley common drain procedure and I have a few questions:
1) What is this hose that is detached behind the freezer? Is it supposed to attach to the freezer somewhere?
2) Would it be possible to tie into the common drain with a Y on the end cap? Or add a Y on one of the T’s, precluding the need to cut PVC?
Thanks!

That little hose looks to be the condensate drain for the refrigeration units - the Sub Zero ones on my boat had drains. They tied into a single line just under that deck and routed to the galley sump at the end of the tunnel.
I looked at tying the sink into that end cap also but didn't want to take the chance of the AC raw water discharge ( the line running into the end) backing up into the sink. Plus the sink was a 1-1/2" drain and I thought it a good idea to install a vacuum breaker - it simply got to a point that cutting in another tee was the answer.

Tom, after further investigation, I found the refrigerator condensate drain AND it was not connected. I’ll be sure to do this now.
As for this second white/clear hose, does anyone know if the SubZero freezer has a condensate line as well? I cannot find any connections on the back.
Also, what is the best way to clean these condensate lines? Maybe get a long, flexible brush? Like a chimney sweep?
Ohh, one other question. Tom, why did you choose not to make a Y at this be of the existing T’s in the PVC and tie the sink into one of those? I want to understand this more. Thanks!

I guess you are talking about the 1 inch line going into the top of the last tee? Putting a Y fitting there would be too small in pipe size and also share the discharge of the hose that's already there. Secondly, a fitting atop there raises the drain connection up which isn't the direction I'd go; there's not a lot of elevation change between the common drain and sink drain. If you notice the new Tee I installed has a 1-1/2" port and it's rolled over so the sink drain enters as low as possible.

Great info. Thanks. Is there a way I could add that port after the two existing T’s. By removing the end cap and replacing it later? I am trying to figure out the easiest path forward. I really appreciate the input.
Also, I will need to find the parts needed as well. I imagine I will need to hunt in a few different spots. Gotta love boats!
I'm sure removing those glued in bushings (end caps) will damage/destroy the Tee they are installed into.

That makes sense. I’m amazed that you were able to get in there and cut 90 degrees. Amazing.

Tom,
You were right. I removed the back panel of the freezer and I found the other end of the severed freezer condensate line. It was hidden behind the panel.
This line is much too short to ever work properly, and judging by the amount of screws and debris behind the freezer, I imagine it has never been connected.
Also, after taking the freezer out 2-3 times and accidentally causing some small marks in the floor, I highly recommend using cardboard to protect from the sharp footings. Lesson learned.

First off, thanks to ttmott and rlynch03. With your info, I was able to get my kitchen sink drain to tie directly into the starboard drain. Here are pics of my install:
A few caveats:
- I used a 2 1/2 inch pipe cutter, but needed small saw to cut about 1cm of PVC that was bonded to the fiberglass support.
- If you decide to update the tubing from the kitchen drain, please be sure to get one that is quite flexible. I went with tubing from Home Depot and it was ROUGH. Not nearly flexible enough for the S-Curve that is needed. This is why you see the flexible coupler needed at the new T.
Thanks again everyone. Great upgrade!
