East Central, Nebraska | I am wanting to bury a water line for an automatic waterer and was wondering if pex is the way to go now or use the black flex pipe. I am T -ing off an old hydrant line that is the black water line and not sure if I should keep using that or if there is something better out there. I have myself witnessed pex freezing solid and thawing out no problem, but am unsure if it can be burried and still be reliable.
Thank you. |

Piedmont, NC | The pex fittings are not good for underground use. I would stay with black. If you have no joints I guess pex would be ok. But I would stick with what everyone uses though. |

NW Montana | you can use pex but most plastic water lines and geo thermal fields use HDPE pipe which is the black flex pipe. I like the 160 psi rated for water service. Never had any issues and always use red brass when you are burying it as yellow brass has zinc which will leach. |

The water line that is "code" around here, now - is rated at 160lbs/psi and can be bought at 200psi. This water line is blue in color (blue indicates water). This blue HDPE coiled pipe is thicker walled also (hence the 160psi rateing). Most pex isn't rated for more then 100 psi, and not rated for outside use (never read anything about being burried, but burried is outside? |

Extreme SW Minnesota Iowa border | I buried some 1' Pex last year for a guy. According to him, 1' is or larger is rated for direct burial. But, I just dug the hole and filled back in. I would check with your supplier. |

Oregon | All the new and replacement urban water mains I see out here are PEX now. I'd run it without concern. -Mike |

NW Montana | Pex is a thinner walled product which is why it has a lower pressure rating than 160 or 200# hdpe. If you must use pex. and I would not, make sure you get fittings that are red brass and rated for direct burial. The same if you decide to use hdpe use the red brass yellow is not rated for direct burial.
