Where would I look to find information how how to install a sink drain FOR DUMMIES. I have been googling all evening and don't find anything. I find plenty of places that sell all kinds of parts. But I need to know which parts I need and how to put them together. What I want to do is something like this.....

I want a small sink that will drain to an outlet on the teardrop, like the one above, that can either be routed to a sewage system in an RV park if that's where I happen to be staying, or into a portable holding tank outside of the teardrop like in the above application.

What parts do I need. Where can I find a diagram of how to put them together? I have looked for books on the subject on Amazon also and didn't see anything that looked like it would contain the informaiton I am looking for.

Thanks!!

Thanks for that reply Slowcowboy. That sounds like a good, inexpensive and simple solution. I like it.

Slow gives good advice and here is a video showing how it is done up to a point.

Ignore the part about the garbage disposal.

I obtained the sink I am using for my build on Craig's List. There are some existing fitting already mounted to the drain. I was under my sink cabinet this morning doing some plumbing and I looked at the fittings more closely. They are threaded to accept the female end of a garden hose. I too must work out exactly how I will drain my sink along with my shower. If it was only the sink I was draining I would a drain fitting through the floor of my trailer in the cabinet and simply screw a garden hoseto the exterior fitting and then in turn to my grey water tank.


My shower complicates things for me however. :crazy:

@standupguy, use a garden hose "Y" fitting between the sink, the shower and the grey water tank. Or a "T" fitting. "Y" can give you more or smoother flow rate for a gravity system though, I would think.

A long time ago I used a stainless steel mixing bowl as a sink.... Just cut hole in bottom that was large enough to accept a drain assembly for a "bar sink"....Why "bar sink", because whole thing is smaller the "standard" sink drain....

Off bottom of drain assembly I just attached a length of poly hose that had a female garden hose connection on it and took hose through floor and let it hang a few inched below "van".... Used "short hose" to connect to catch bucket or what ever we were using for "gray water" at the time...

Yes there is some adapting involved, but then its all about the build...

Well, I need maximum diameter with minimum depth. (depth of sink plus drain elbow <= 4") Boy, I could use a 9x13 pan even then, little modification to the drain area slope with some basic pressure. Buy at salvation army for $0.50. Rim of wood. Drain as you say... of a basic screen and 1/2 inch fitting and elbow.

If you want to get REAL simple, I have been thinking of using a hinged fold down sink, that rests on top of one of those new kind of liquid laundry detergent jug. the ones with the caps that drain inside the bottle. Then when filled just go drain it, swap in a second one... Lots of possibilities there. If you are going that route and don't want to go "power faucet" yet, you can get one of those camping water bags with the spigot, that has a hanging point, opposite the spigot. Just hang it over the sink.

I now have an idea to have my fill point at the right front corner soffit/eaves... That would give me an access point, semi-hidden, with some elevation for the venting. I'm wondering now, we have the grey water storage and drainage. Even slip some chlorine down there for cleaning, is there grey water flushing? (pressure inlet -> flow through grey tank -> to grey drain?) to clear out any sediment of dirt?

Have you considered a "hotel" pan like they use at the local buffet? A full-sized pan is 19.5x11.5 inches, and come in a variety of depths and sizes such as 1/2, 1/4, 1/8 etc, and from 1-6" deep.
I would check out some of the local restaurant supply houses, a lot of the time restaurants open and then close before the ink is dry on the purchase agreement, and they have a large selection of used equipment. A new full pan 3" deep can be purchased online for about $20, used much less.

These buffet style pans are available at Sam's Club for not too much, and that's an excellent suggestion!! I wish I had thought of it before I bought my sink.
