Plumbing--sources??

[Guest]

While performing maintenance on the seacocks--another story--I noticed the fittings from the pigtails of the twin bowl galley sinks had corroded. Anybody have this problem?

The sink and pigtails are stainless. The drain pipe is brass, and the fittings were ???? and crumbled. I would prefer to replace the original just to ease the installation. Defender has a twin drain pipe, but I wonder about the distance (drain center to drain center).

So any suggestions?

In a few months/years I expect my back & arms to return to their pre-seacock maintenance condition. Amazing what a few hours in generally supine positions on the cabin sole in 34F temperatures can do to the misery index.

Hi Mitch,

If you don't insist on using original replacement parts, you might consider using PVC type pipe and fittings. All necessary fittings and pipe are available at most hardware stores and home supply centers.

It's very easy to work with. The pipe can be cut to size by either a tubing type pipe cutter or with a hacksaw. A lot of tail piece drain hookups dont require threading. They have slip fittings with threaded gland connectors. The cost is very reasonable. If you make a mistake, toss it and cut another piece. It will never rust out. FWIW.

Good luck,
O J

I installed the defender dual drain on the galley sink of our CD 33, and it went very well. Had to cut the old system off with a hacksaw as twenty years had frozen it solid.

We replaced ours with hardware store PVC except for the hose which is real boat stuff. Seems to work fine so far and the price was right!

Anybody know what brand of sink CD used? If not, there is a freezing trip to the yard for measurements.

Speaking of hoses, pipes and fittings, I noticed that manufacturers seem to take quite a bit of liberty with their ID and OD numbers.
A "specialist" was dumbfounded when we went searching for some hose to fit a certain marine fitting. Three different manufacturers each had different dimensions for the same size hose! One was so loose, it would still slip off after applying two clamps on it!
Finding the right sizes that match up tightly can be a real headache!
You would think there would be some real standards for these items.

Here's the simple solution:
First the sink drain is 1 1/2". This is known in the trade as a bar sink.
Second replumbing drain kits for dual sinks are generally available.

I needed to cut to length the horizontal pipe which connects the two drain fitting. I'll test for water tightness after the temperatures rise above freezing.
