Plumbing Removed?

1993Brave · 03-20-2021, 04:41 PM

Hi! Just bought my first motorcoach. It's a 1993 Brave 31 foot, and a project. Under the kitchen sink, someone removed all the drain pipes and they're not to be found anywhere in the camper. I have no idea why! I found a diagram on the Winnebago website, and I'm going to rebuild the system. But since the diagram is not in 3D, I'm having a hard time figuring out how to configure everything. Does anyone have a photo of under their sink that shows me how it's supposed to look when the job is done? I've attached photos of what my sink under looks like now. Thanks all!

Not got that model but it is pretty standard plumbing and you likely have one in the house where you live!
Called p-trap and they come in different sizes, mostly 1 1/4 or 1 1/2 but they are just a set of adjustable length plastic pipe so that things don't have to line up exactly nor be exact distance apart.
You want the size which matches what you have and then it is a matter of fiddle around to get them like they will let water run downhill.
But a simple trick I learned to use is adding a bit of silicone caulking under the plastic fittings that screw together and letting it dry totally before running water.
Plastic tends to swell and shrink as it warms and cools and that tends to make the fittings get loose but the silicone holds them and still not so tight it can't be worked later.

I also need to figure out WHY the plumbing was removed. Was it leaking? Are the tanks bad? I also need to see if any more plumbing is missing - like under the lav sink, the toilet, or shower? Yikes!

...someone kicked the bucket on the way to the hardware store!

If so, you can probably count on this being an isolated issue.

Besides, it looks pretty clean under the sink. So no big deal. Just treat it like you would a sink at home.

Installing a new P-trap and hooking it up to the sink basket is pretty simple stuff. There are probably YouTube videos on the subject. Generally no tools are required; hand tighten only.

Looks like all the parts you need is a 1 1/2 inch P-trap kit and the tail piece for the sink bottom.

I see in that photo that the hot water bypass valve is in bypass mode for winterizing. Could it be that the P-Traps were removed for winterizing too? Or maybe they froze and someone removed them to replace them and gave up on the 28-yr coach???

Good luck.

Copy your house kitchen sink drain. Some thing. Buy plumbing from Menards or such.

Hard to tell, but it looks like there is a 90deg hose barb that isnt connect resting along the back wall. Check that out before turning water on.

We squared all that away. Other half did a bang up job. Now I’ve discovered some leaks at the sewer drain valve, so that’s awesome.

Hi,
We have a 1993 Brave. It is a 27RC model. Let me know if you still need photos and and I will be happy to help.
Cheers

Judging by the floor in the cabinet, it doesn't appear to have been leaking. My guess is removed to winterize, which would be odd but VERY effective - it can't freeze if it's not there.
It's standard plumbing, look under your sink at home to get an idea of what needs to be done - you just need to make sure you match the size. There is no need for it to 100% match what it looked like new, it just needs to get the water from the sink to the pipe that leads to the holding tank.
I too would check under all other drains to make sure the same wasn't done there.
