Inside plumbing

[WFD]

Is the inside plumbing in most trailers typically 1/2" pex, if one wants to make some modifications is it as simple as using 1/2" pex fittings from Home Depot or Lowe's? Are the crimp fittings the manufacturers are using the same as the 1/2" pex crimps?

Yes. Crimps can vary, but you can check the brand of tubing and make sure the crimps are ok for that brand. Usually package will say, works with these brands. All mine are the cinch type. Some of my supplies came from Lowes. Carry a supply of spare stuff with us as well.

Oetiker cinch crimps is what I've used, but the ones at lowes work too. I've got most all of my pex stuff at Pex Tubing Store on ebay

LOTS cheaper and can buy in bulks. Got all of my shut off valves for sinks, toilets and everything else from there.

And how easy are those cinch clamps to remove. I only have 2 to remove and was hoping to not go out and buy a special tool to remove them. Hoping to re-use the fittings that the current pex is cinched to.

I've not figured out the trick to "easily" remove the cinch clamps, nor have I ever seen a tool specifically for this. I've used a die grinder before, when I just needed the fitting, and one time a flat heat screw driver, where I needed to not damage the tubing. I did get them off, and reused some of the fittings, but it wasn't extremely easy. I have a tool to cut the other crimp style that requires a go / no go gauge, but I like the cinch ones way better.

I use a course file to remove the crimp clamps on the fittings in our TT.

Well there you go. Another way to do it. Never thought of that way. Thanks for that tip.

The PEX instructions say to cut off the end that was previously clamped and use a new clamp. I had to redo a fitting under the kitchen sink and I used a screw type hose clamp purchased from Lowes. Worked fine.
