If blue is for water, and yellow for wire, what is the white pipe for?

Yes they do have yellow boxes for yellow pipe.

Other colours white or green,grey can be used simply to differentiate services, such as airconditioning, cctv, swimming pool electrics.

Saves confusion if at a later date you forget where services are routed

Sanme Same as color coding on wiring - no confusion there

White is for plumbing

Blue is for drinking water

Yellow for electricity

Gray for industrial fluids and irrigation

? The white pipe is too small for plumbing ( sewage ). The Thais building the accomodation next door are using large blue pipe for sewage.

Thanks for the replies.

Then buy a bigger white pipe LOL

Smaller diameters are meant for things like sinks, basins, bum washers etc.

Hardly anyone actually uses white pipe though.

Go read the tech docs for any of the big pipe manufacturers in TH, and those are how they all explain the colors

We've used white for a run (supply and drain) to the outdoor sink (an afterthought) as it matches the painted wall.

Yes really it doesn't matter one jot, we could be pedantic and say there is no such thing as drinking water via blue pipe here, and as crossy says you can choose whatever is going to be least obtrusive, although the blue does generally have a thicker wall for water pressure,and protection from damage.

Our local pipe-shop has white PVC in the same pressure ratings as the blue, less choice of fittings mind.

They also have electrical conduit in yellow and white (thin walled for electrical).

Just a heads up for those that don't know, there are about three different grades of blue pipe.

I found out the hard way by buying the cheapest - it got brittle and cracked after only a short time.

And for anyone messing about with hot, pressurized water, use the bloody expensive green pipe.

Thanks. Interesting points.

However, I've never seen large diameter white pipe on sale. What I've seen is small diameter.

or better still the white 3-4 walled flexible pipe on sale at thai watsadu with o ring fittings. Buy it on a roll same as Hep20 in the UK

Haven't seen the stuff you're referring to, but I can't imagine flexible pipe being rendered into a wall and not causing problems?

Any idea what it's heat rated to?

My guess that is referred to aluminium tube with Teflon coating inside and pvc outside

Can stand very high temperatures ( more then 100 degrees Celsius)

That sounds like high grade PPR though, which is the opposite of flexible?

Curious as to what kannot is referring to.

It is flexible, they sale it on the roll. Wide corners you can bend by hand. For sharper corners you need a special tool (that tool never seen overhere). Must also paid attention to cutting it on length. Do not use a saw.....

After a little searching, I think I've found it... Looks like this?

Also wire. With the white pipe they als have junction boxes. I did not see these for the yellow pipe.

Seems popular, Found this picture e.g.:

Plumbing, that would be the big pipes for toilets etc. (mostly grey though?).

The white pipes are popular for do-it-yourself in the home, like building a baby "safety gate".

Not sure if kannot ment this,

But this is the stuff I know.

It seems I was wrong with the inside, and outside materials.

Thank you both for putting me onto this - just what I've been wanting

White pipe is for installing electric fences!
