How Deep to Bury PEX Water Line?
PEX pipes and all underground piping should be buried at least 12” to 18” below the frost line to protect the pipes from freezing. The frost line refers to the furthest depth underground groundwater begins to freeze, also called the frost depth. In colder zones, the frost line can be three to four feet down. You can check specific data from the US Department of Commerce or refer to this map of US frost lines. Values range from 0” up to 100” underground.
What Type of PEX Is Best for Underground Use?
PEX – cross-linked polyethylene (sometimes called XLPE) – comprises ethylene molecule chains, or polymers. These non-connecting polymers create the flexibility of PEX in two density types – high (HDPE) or low (LDPE). HDPE has tighter packed polymers, giving it more impact resistance than LDPE. When HDPE goes through a process called cross-linking, the unconnected polymers become connected.
Is PEX or PVC Better for Underground?
PEX and PVC are both types of plastic. PVC though, is a hard rigid pipe (think of the plumbing under your sink) with no flexibility, while PEX is extremely flexible (except for PEX-C). PVC (and CPVC) was around years before PEX, making it a more common choice. Many experts will still recommend PVC over PEX.
Can PEX Be Buried in Concrete?
PEX is an HDPE (high-density polyethylene) material which makes it strong enough to handle going inside concrete. This tolerance and PEX tubing’s flexibility make it common for radiant heating embedded in concrete floors.
Why is PEX pipe bursting?
The high-pressure potential of PEX means that there’s less risk of the pipe bursting due to the water turning to ice. When ice forms in hard lines, there’s a higher risk of the pipes cracking or bursting. Remember though, the repeated expansion and contraction action can cause the tubing to weaken, leading to the pipes leaking or failing. In addition, if there are cracks present when water freezes in the lines, it could cause the tubing to rupture.
What is PEX tubing used for?
PEX tubing has many uses. It is mainly used for residential water lines but also as transport for heating and cooling components, chemicals, and even sewage. PEX can be used in most instances where you’d use pipes made of copper, CPVC, or PVC.
