Can you use blue PEX in place of red PEX

[Truckman]

Have blue, can’t find red

[rowdybass]

Yes, just remember that it’s a cold line not hot.

[Tx.Fisher]

Yes

[Truckman]

Thank you!

[TacticalCowboy]

No you'll blow your toes off

[rvd]

I’d mark it with a sharpie if you’re saying you are running 2 blue lines (hot/cold).

[ColinR]

If you use blue for a hot water line the water will never come out hot. You will only have 2 cold lines.

[bboswell]

get some red marking tape from the electrical dept and wrap the ends of the hot line

I wouldn't chance it. You might really mess something up.

[ken800]

I ran out of blue/red on a remote job. Had some white and some red/blue sharpies. Marked them that way. Get some tape as mentioned above.

Note that if you use white tubing you will get neither hot nor cold in either line -- just lukewarm. If you mark them, though, it's all good.

[friscopaint]

Either one just make sure its pointed in right direction or water won't work if backwards.....

There’s a reason they make red & blue, so you can identify which pipe is which later!

But I guess we dealt with that with copper for years and survived.

Still a BS move on the plumbers part

Pex is pex !
Only color coded for differentiation.

My house was built in 2014. They used a pex like product. It is grey or white but have had no issues. I may be wrong but if looked like it had a metal liner inside of it. Could have sworn they said it was a german product but comparable to Pex.

[Hoss163]

Nope water want get hot because it’s blue pex only works for cold water ����

[asu-indian]

All the same bro.

Why cold water is on right hot water is on left water doesn’t know what color of pipe it’s flowing in . If the plumber knows his right from his left what are you worried about?

Fostapex (ViegaPex) most likely. Great product used mainly in ground or slab but does come in red/blue/grey. Most just use the 3/4 grey for supply line.

The idea that a plumber doesn't know his left from his right.

I would think the contract would have a lot to say about that.

If the contract said red and blue would be used yes he changes if it don’t say anything about the color he gets paid.

So, what happens when you pull both white pipes down the wall at the same time?

You must be joking. If you haven’t been to the PACE forum lately I guess you might not know that we’re done and life as we know it is over and there’s no return and we now live in a banana republic, 3rd world, communist country.

[Buck hunter332]

Most of the white/clear pex Will have red or blue lettering on it to identify hot cold

I think it grey stuff is what they use to use in trailer homes .

[Big Lee]

This is 2021, even water pipes can identify as anything they want.

That gray pipe was called Quest, right? The problem was all the water ran luke warm because it was all one color, not red and blue.

[coker737]

Your right it makes it easier but white can be used for both . It’s not illegal are done wrong if you use just white. You can always write hot on one and cold on the other to know what is which are get red and white tape and put a strip of red on hot are strip of blue on the cold . We had to deal with it with copper. Because they dang sure don’t make red and blue colored copper. And when I ran copper under the 100s of houses I roughed in I would run all my cold waters first and then roll out all my hot waters. But if was going to pull white pex only down the wall I would mark with a marker which one was cold and hot .
