What Kind of Water Line?

[mhopkins]

I am wanting to re-position my water pump a bit to make access more convenient. And I need some of the white (high pressure?) water line to accomplish what I want to do. But, I am having trouble finding out what kind of line this is and where to get a couple of feet of it.

Imprinted on the water line is "PRESSURE NSF/ ANSI 61 IAPMO . . ." (see pic at link below). I have learned that NSF 61 indicates that the line meets standards for drinking distribution systems. But that's as far as I have gotten.

Any counsel would be greatly appreciated!

Would guess it to be white pex


1/2 in. x 25 ft. White PEX Pipe

Standard 1/2 inch Pex line. Available at any Lowes/Home Depot/Ace Hardware.
When buying, they will almost certainly try to sell you a Pex Tool so you can crimp the ends. However, ask them to show you simple 1/2 inch "Gator" or "Sharkbite" fittings. Work just as well, cheap, and won't leak.

Alas, this is not PEX. This is much smaller in diameter, is (a bit) flexible, and seems to be nylon-reinforced.

I recently had a fitting leak at the outdoor shower connection on my trailer. The fitting was some how cross thread so, I needed to replace this hose and the outdoor shower faucet. The plastic threads were damaged on both pieces. I had a dealer make up a new 1/2 PEX ($3.14) hose with fittings to replace the ruined factory hose. PEX hose will work but it tends to be a little stiffer. You need to have a larger bend radius with this hose material and can not be routed with a sharp bend. So, plan accordingly when moving your water pump.

I think your Google Drive link is private, I can't access it. I'm VERY surprised it's not PEX, the vast majority of RVs are.

I can't see the pic but for a project like this I would recommend 100 psi 1/2" braided PVC hose for flexibility and to absorb the vibration from the water pump.

When I looked at my pump, I recall some of the tubing to be what I would call ”Tygon” tubing; I think manufactured by Nalgene. It is a braided polyethylene (?) tubing rates for higher pressures.

RV parts stores will have what you need including a coupler if needed. There is nothing high pressure in the trailer unless you don't use a water regulator on the city water connection and then it could be anything.

It's this stuff.

Just looked at my setup. It also is white and looks like what you described. goes from fresh water tank to pump and about a foot of pipe out of pump to cold water pex line. Also used for anti-freeze pickup line. Much more flexible than pex and I am thinking able to absorb vibration from pump motor. It is Valterra 1/2" ID, W01 2105 NSF, cold water only, 150 psi.

I have seen this pipe in RV stores. As for bending pex pipe you can buy a plastic guide that allows pex to bend at a fairly tight angle and keep it in place also can be fastened to framing or whatever.

Using a heat gun with on PEX (with moderation) works very well. Keep twisting the pipe as you heat it, then bend carefully. This works best if a helper holds the heat gun as you twist the pipe. Continue to heat it as you make the bend. If you go slowly, the pipe won't collapse at all.

I've actually done this with 2" PVC and a Bernz-O-Matic, too, when constructing my last house.

Many of the big box stores don't carry the white in bulk but you can often get supply lines long enough to make repairs or splices.

Here are some at HD...

See Post #21. $10 for 20 feet bulk at Lowes. No fittings on either end.

Lots of options, most will work some are expensive. As I stated earlier, 1/2" braided PVC hose it commonly used.

Whatever you end up doing, do not connect Pex directly to the pump, it is not flexible enough to absorb the vibration and will eventually shake the connections loose.
Use cinch clamps or slightly widened copper Pex clamps on the fittings, no gear clamps if you can help it!

[Villagerjjm]

You do not necessarily have to use the braided line. You can use PEX which will also allow you to use SHARKBITE type fittings. They have the blue and red PEX at Lowe's in the same section. Have one of the plumbing guys show you how the SharkBite fittings work.
It will almost seem too easy!
I saw a response about PEX not being as flexible as the braided tube. It is true that PEX is more rigid, but it will hold a curve better than the tube will, which means it will not crush as easily. The braiding is imbedded only to help prevent bursting from pressure. It does not prevent collapse from tight curves. You can get curve holders for both types. I would definitely recommend it for any bend beyond 45 degrees.

A few years ago I was in need of a hose that would hold pressure for my toilet in my TT and was in Mackinaw City. Tried a lot of possible places and then came on a marine supply store (Sheplers) and they had just what I needed. It was a hose as you described and was rated at 250 pounds pressure. I could buy it by the foot and they had various diameters available. I would presume you can get this type of hose at other marine stores as well where you live or are camping.

Yep.. the OP asked for white.
Your link was for clear.
