How many ft of PEX to replumb Caravel

Has anyone replumbed a Caravel who can give me an idea of how many foot or PEX I'm going to need? I'm just adding up what the damage will be if I decide to go for it and replumb the whole thing.

Pex is dirt cheap. Fittings will kill you. I bought a roll of red and a roll of blue for the Safari, and still have tons left.

One 50' roll was enough to do my Overlander, with plenty leftover.

Rather than buy two large rolls of differing colors and have something like 70' leftover, I just bought a roll of the clear and used red and blue electrical tape to color-code the lines.

Yeah, I was thinking I'd just get a roll of the clear, looks like I can get it in 25ft rolls, or 8 ft straight sections.

Adding up the fittings alone I'm up to just over $100 for flair-it fittings. I'm still researching the other kind.

Right, the fittings are definitely the expensive part. I really liked the Flair-it fittings, I used a combination of those, and the Jaco fittings, because Forums member GreatPumpkin had a bunch of extra ones that he sold to me at a major discount.

As for the pipe, probably 3 -5 straight sections would cover you, but I liked the roll because I had two runs that were over 8', and I didn't want to spend more money on an extra union fitting, as well as creating another potential leak point. You'll end up with overage on the roll, but with the straight pipes you could end up with unfortunately sized waste pieces.

Looks like the brass crimp fittings are going to run about $50, so half what the flair-it fittings cost.

I have read that the brass fittings can crack if they freeze (though it is not my intention to screw up and let the system freeze again), but I would think the flair-it fittings would be just as susceptible to cracking. Does anyone know?

Steph, Our local hardware store sells it by the foot. Might be a little more expensive by the foot but less in the long run. My window covering shop is next to a heating & sheet metal store. They are always throwing out pex pieces 4ft or less. I'll check the dumpster for you.

Dumpster plumbing - yay!

Our local hardware store was no help - I ended up talking to three different people, and the third guy got frustrated because he didn't know what I was talking about at all - never heard of PEX! Funny, he has a whole section of PEX fittings, you think he might sell them from time to time. But I found a plumbing supply not too far away which has everything I need at prices comparable to mail order, so I think I'll be ok for supplies once I figure out exactly what I need.

When doing the PEX lines in my TradeWind, I only bought the clear by the foot and just colored the hot water line. Once I was done with the plumbing, I wrapped the hot water line with that split grey insulation that you get from the home centers in about 6' lengths. There is no mistaking which line is which now and my water is really hot all the way back to the shower.

I bought the tubing at a place called Menards (kinda like Home Depot). It was like $8.00 for a 25ft roll. Bought a roll of blue and one of red. Had a lot of red left over. Got the Flair It fittings online at www.iplumb.tv

$8 for a whole roll!! Wow, what a deal! It seems to cost more like $1/ft around here.

I compared prices with iPlumb.tv and the local plumbing place matches or beats their price.

It's not the Pex or fitting that's expensive, it's the special tools you need to work with Pex.

No special tools required for Flair It fittings. There is a plastic wrench that you can buy, but you don't need it, I used channel lock pliers.

Right, the crimped type of PEX fittings DO require a special crimping tool. This tool used to be quite expensive, but the prices have come down over the past few years, and I also hear that some places will rent the tool out.

But Flair-It, Sharkbite, Gatorbite, Jaco, and several other types/brands do not require the expensive crimping tool. They either push-in, or twist with simple tools. I bought the special plastic Flair-It wrench for a couple of bucks, and it was handy, but channel locks would have worked just fine as well.

Stef-- I don't believe the Flair-It fittings are susceptible to freezing, really at all.
