best type of material for re-plumbing?

what is best type of water pipe or line to use when re-plumbing older trailers? have removed all old copper and want to go back with all new. have considered PEX, but fittings are costly. What about PVC/CPVC or even braided reinforced vinyl? am wide open to suggestions. trying to keep costs down as well.

PEX is your best bet due it's flexability for installation and resistance to breaking if frozen (not under pressure). It comes in colors so you can readily identify hot or cold.
You can try PVC but it will be hard to install since most of the plumbing was done before the interior was installed. CPVC (black stuff) is for drain only.
You can try braided vinyl but is is prone to kinking and not very resistant to spliting if frozen.

PEX is the way to go. The Flair-It fittings work very well and do not require in special tools. I installed PEX and Flair-It fitting throughout in my 1976 Sovereign back in 2000 and have not had a leak or problem with this installation.

I would go with PEX

I have PEX in a not so well insulated part of the house. It has frozen
many many times, with no resulting damage. Also, I think, that PEX
will handle vibrations and the shaking around that RV plumbing gets, way better than rigid plumbing materials. I think it is easier to install.

I would go for PEX and I will probably spring for the tools since I have several trailers to do.
I have 61 is plumbed with household CPVC. If I have the terms right CPVC is not the black stuff. CPVC is yellowish in color and glued together. ( just looked at a piece and it says CPVC) The white pvc is not approved for hot water. Don't know what the black stuff is called

I was kind of skeptical of the CPVC job that was in the 61 but I left it in place and it has survived 6 years and several cross country trips. It appears the PO heated it slightly to curve it around bends

From what little research I have done if one worked with PEX much the money saved using crimp fittings would fast pay for a crimping tool. The other fittings I have seen seem pretty pricey to do a whole trailer.

Pex seems to be the material of choice in the new RV's I have looked at.

It also has the advantage of coming in colors so hot and cold can be identified later

PEX, PEX, PEX! We also used the sharkbite fittings which are indeed expensive but work quite well if properly installed.

PEX. You can buy a hand expander and head for $200.

ProPEX Fittings , PEX Plumbing , Wirsbo ProPEX Plumbing , Wirsbo ProPEX Plumbing , - PexSupply.com

These types of fittings are cheap and trouble free and a much better way to go than the sharkbite etc which while fine for the occasional repair do not have the track record and low per fitting cost of expansion fittings.

PVC/CPVC - brittle - will turn to powder if it freezes once. An obsolete material for water pipes.

Soft copper - at $3 a foot plus fittings PEX is cheaper if you're doing a whole trailer even with the tool costs. I did my house with this but that was before copper prices skyrocketed.

Hard copper - still around $2 a foot and the solder connections are prone to leakage when subject to vibration. You can use the propress fittings but the tool costs are even higher than for PEX, so why would you?

Ditto on the pex. It's flexible, easy to work with and cost effective.

You can rent a crimping tool for about 20 bucks a day. You could have all your stuff cut and ready to go and do all the crimping work in one day easily and not have to buy the tool.

Go with pex,you can buy a crimper at lowes for 75 bucks.

If you want to save $, get your fittings at a plumbing supply house.

Black hard pipe is ABS which is typically used for DWV (Drain, Waste, Vent) applications.

Black flex pipe is poly pipe. Poly pipe is typically used in irrigation and water well applications.

I noticed in HD the other day, a tool for crimping pex fittings that is only $25. I can't find it on their website, but it is a clamp-like device, with several size holes, for various sized fittings. not sure of the name for this type of tool...maybe a "die block". Anyway, the "squeeze" comes from your vice-grips. (don't know why the label said to use vice-grips, vs. any other type of pliers).
The interesting thing about it was that it looks to me like you could use this tool in the cramped spaces of an airstream. Thats what looks impractical, to me, about the standard crimp tools. not only are they expensive, there's no way you'd ever be able to use such a large tool, unless you were re-plumbing a completely gutted trailer.

Here, I found it:

Pex Crimpers
I saw this at the orange box as well, and would be interested to hear if anyone has used it successfully? For curiosity's sake of course, as I've already completed my re-plumbing using PEX and a combination of Flair-it and JACO fittings.

But if it works, then it would make using the crimped connectors VERY affordable, even for relatively small repair jobs.

You can rent the crimpers at HD (around $20/day) and I can also verify that getting those big tongs into position to crimp a particular fitting in a trailer can be very difficult. Mis-positioning of the crimpers leads to faulty crimps which leak, though the copper bands are cheap and relatively easy to cut off and give it another try.

Go with the PEX. I used the vinyl and it tends to need the clamps tightened now and then. Set it up so when you drain the system all fittings drain. They don't like to freeze. Should be a once and done. No fittings where you cann't get to them easily.

There are also fittings that do not require a special tool. Use compression.

I used PEX like most of the other posts, I messed up on my first fittings and went with Quest fittings. They were terrible. I spent the money and bought shark bites. I have had everything running for a year and no more leaks.

Buy the tool and go with the pex. It opens up options for routing your plumbing which can be a great advantage. Here's one of the pictures of one of my installs.
