PEX Piping


A type of tubing made out of high-density, cross-linked polyethylene used in plumbing and hydronic radiant heating systems.

Things you need to know

Compared to CPVC, PEX is more flexible and less likely to burst if it freezes. It does not require glue like CPVC, so you do not need to work in well-ventilated areas or use a respirator. Compared to copper, PEX is faster to install and does not corrode as might the latter.

Cross-Linked Polyethylene Piping, PEX Tubing, PEX Tube

Cost Considerations

The price for one hundred feet of appropriately sized PEX piping averages $40 per roll. It costs roughly the same amount as CPVC and is much less expensive than copper (about a third of the price).

Costs vary greatly by region (and even by zip code). To get free estimates from local contractors, please indicate yours.
