John Palmer, I've been looking for a plumbing post that I think you made about running plastic pipes under the trailer for toilet and gray water but remember that I thought it was brilliant solution but can't seem to find it now. We are thinking that we would like to try it but not sure if our little guy has clearance for it. How can I find that post?

It will be interesting to see if the pex fittings hold up over time with normal trailer travel....and also in residential applications. A sure way to save on time and labor though. Personally, the pyro in me likes sweating copper.

Personally, the pyro in me likes sweating copper. Pex was slow to adopt in the US, Europe has been using it for at least 10 years before we even thought about using it. The best feature about PEX is it has a memory and will not burst if it freezes, it will slightly bulge and if you take a hair dryer to it, it will go back to it's original shape and size.

Where I live PEX was only recently allowed...my guess is due to heavy lobbying from people that stand to lose money due to its cheapness in both material and labor...but why would you ever want to own a product that has very minimal failures or maintenance issues?...

We are thinking that we would like to try it but not sure if our little guy has clearance for it. How can I find that post? Dawn, This might be what you were thinking? I wanted to have a toilet, but did not want the weight (water is about 8#/gal) of a holding tank on my 17' "single axle" Mallard. Basically we wanted a system to be able to use the sink and toilet for a day or two during highway travel. When we get to our RV site, we just hook up, and dump. We did not need much volume, so here is my solution. The toilet flushes directly into a large 3" ABS pipe, it goes all the way to the opposite side of the trailer, enters into two "large sweep" 90 degree elbows, and then back to the street side of the trailer. It has maybe one inch of drop for drainage. The mini holding tank is the total volume is ten feet of three inch ABS pipe. It's worked great, never has been full.
The only thing I would do different, on my next trailer is that I will have a separate 1 1/2" waste valve drain for the option of separating the grey water, before it enters the main black ABS pipe.

I have had PEX on my Mallard for the past year without any problems. I just finished a 1953 Silver Streak, and used PEX for the plumbing. I use the Sharkbite fittings that require the copper crush rings.

Yes! That is it! Thanks so much. We are FINALY going to get all the final things on our pick list done first thing this spring so we can enjoy a long epic road trip this summer. Once we get started I'll probably be getting back to you on this if we have more specific questions on how the install should go. Rob is thinking we might not even have enough clearance under ours to do it but I have my fingers crossed that we can figure out a way.
