Just curious. Why in USA (or maybe in Canada too?) PVC pipes are mainly used for watering, plumbing, e.g. home water supply (not sure how to call it correctly) . More of it , they use GLUE to join them. I think this has many disadvantages - PVC can break easily, the glue is toxic and takes time to cure, etc. Why don't they use PPR ? In Russia, PPR is used everywhere - it's strong, cheap, and it WELDS simply within minutes. here's a quickly google'd example: www.buildmyowncabin.com/geothermal/diy-geothermal.htmlisn't that stupid? what you think? |

www.who.int/water_sanitation_health/hygiene/plumbing10.pdfHere in the USA We have way to many choices. We just get used to one type plumbing and another type comes on the market. Yea pvc can break and is not the best but it is fast and easy. Glue sets in about three min. PEX Is about the latest new plumbing around here. No Glue but more expensive fittings and special tools to install. Not as handy as pvc or cpvc cut/glue done. Oh yea.... The glue fumes only kills off the weak Brain Cells making you Smarter!

When I Click on those Links, Neither one Works.
For Water Pipes, I Prefer Copper.
Actually Galvanized Steel is Healthier and Better.
I have an OLD HOUSE, Mostly just Steel Water Pipes.
Gives you a Bit Extra Iron when you drink the water.
For Drain Pipes, I like ABS.

That's odd Gary.
They both open for me.
My old house was full of copper plumbing. I used lead solder on all the joints to.
Yea I know it's bad for you but the tin junk sucked!

Yeah copper is good and well known here, but ABS for drain pipes?! another mystery! because here in Russia we have never heard of drain pipes OTHER THAN metal and PVC !! there is "gray" pvc or "orange" PVC (positioning as indoor and outdoor drain accordingly), but ABS  hmmm... What im trying to understand, is that simply a gap due to technological lag of Russia (compared to USA) or some traditions/standards which exist independently but are technically equal to the user (ex. PVC pipe ~ PPR by its properties)? |

Copy and paste from the net... Both ABS and PVC are used in pipes because they are non-toxic and resistant to abrasion. ABS pipes are easier to install compared to PVC pipes, but also more likely to deform when exposed to the sun. www.diffen.com/difference/ABS_vs_PVC |

They Don't Deform.
PVC just becomes More Brittle in the sun.
I have some ABS Outside, Been out for Years.
Just Changes color a Bit, but doesn't seem to really Damage it.
I Only like ABS, easier to glue.
I Just use MEK to glue it.
