will do . I am ordering a marine type hose inlet to mount also. I hate the hose hanging out of the trailer. Looks like the I will buy is 1/2 " pex tubing with Sharkbite connectors ...Maybe a small manifold but I figure less than 10 connections total. I am guessing all the sinks take 3/8 connetions?

2 Kitchen 2 bath faucet, 2 shower, 1 toilet, 1 water heater, maybe 1 outside water.

I will be sketching this weekend while I pull out my old Dometic fridge.

I plan on doing PEX in my trailer as well. I did my entire house in PEX and it is a great system. Instead of buying both red and blue to hot and cold runs, I bought red and blue electrical tape and put a band on the fittings to distinguish them. That way I only had to buy 100' rolls of white pipe in each size. For making tight curves, use one of the plastic braces or a 90 for tighter curves around the water heater, etc. My house system has very few fittings, just a few manifolds with direct runs to each fixture. It makes for a very quiet and efficient system.

I went with Uponor fittings for my house and bought the expander tool for $300. I would consider selling it after my projects are done, if ever. FWIW the Uponor tools sell for 90% of retail on eBay.

Anyone use heat trace tape on their pex to keep everything warm in winter?

Has anyone installed an on-demand water heater such as the Girard?

Cheers,

JZ

Pardon my lack of knowledge, but what is "heat trace tape"? I was thinking of insulating my runs with the foam sleeves.

The Quick-Cinch clamps available at Lowe's for use with PEX and brass barb fittings work great (better than the copper rings) and the crimpers for them are affordable (~$40). They also stock a clamp remover if you need to try again because you weren't paying enough attention and poorly cinched a clamp.

Does anyone know how to test your water lines to make sure there are no leaks after you run new PEX? I used the Sharkbite fittings and want to make sure all the connections are good before I put everything back together.

You could always pressurize your assembly with compressed air (50 psi or less) and squirt a soapy water solution on each connection and look for bubbles. The way that plumbers test a system is they install a very sensitive pressure guage in the system and pressurize the system with air and valve it closed and then they come back and look at the pressure guage in 24 hours to see if it has dropped any.

Good idea. I'll see if I can get a plumber to come out and check it for me.

I never tested anything. Just pressure up your system with water and look for leaks. If using an expander tool such as the Uponor that I have, wait 10 minutes for all the connections to relax and get a good bind on the fittings. If you have crimp-on fittings or sharkbites, no wait necessary. Of all the fittings I did in my house, I had only one leak. It was redone and no problems after that. PEX is very easy to use and it is very unlikely to leak. The hardest part of my PEX work was having to sweat a few copper fittings to connect to my main supply and to the sprinkler system.

Timely information. Thanks.
Does anyone know, or have any info on the effects of heat on the PEX tubing?
This winter’s project is to rebuild the sink cabinet and fix the plumbing mess jammed in the back corner. The lines run under the furnace.
Yesterday I tested the "new" NT-30 and it gets really hot at the outlet, right above the pipes. The lines also make a sharp "S" curve to come up off the floor and run along the ductwork to the water heater and fixtures in the back.
What do you think? Keep copper in that location or run the PEX straight through. Does the PEX tubing have a memory? Could it be heated with a hot air gun until pliable and then formed to the "S" curve?
I’ve got plenty of time to figure this out, but with an open thread I thought I’d toss this out and see what sticks.

Pex won't bend that sharply. For a pex bend that tight I think you would have to use 2-L's.

If you are using crimp connectors ( I did ), make up your joints as a dry fit and mark the orientation of the fitting and the tube with a sharpie. The fittings tend to turn a little when you are getting the rings in the crimper and that will cause problems with alignment. In fact, I found that if you mark the fittings, put a copper ring on and just lightly crimp it with a pair of pliers, it will stay where you want it as you put the big crimp tool over the rings.

Small leak in new unit!

This is a timely thread. On the road after picking up our new 2011 27fb Safari. This trailer is such a beautiful thing, airstream has stepped up. There is just one small thing, there is a small leak in the bathroom behind the toilet. AS used pex without the copper pex fittings. When I use water from either sink, there is a leak that puddles behind the toilet.

How do I go about fixing this? Can I recrimp the clamps?

I love this trailer!

Nancy

Ps will post new pics of unit in my first post "we did it" after I get home and settled!

Made a typo. AS used pex with copper compression fittings (not without the copper fittings) in last post!

pex to fresh water tank

I will also embark on the plumbing journey this weekend. I have 1/2" PEX, Sharkbite fittings, and a polyethylene fresh water tank.

Do I need to use plumbing tape (pipe tape) on the male Sharkbite fitting that will go into the threaded female tank outlet?

Thanks.
