How to crimp a drain line with a PEX?

Insert the crimping ring over the pex you want to use for the drain line. If you’re joining the pipe with another one with a fitting, insert the pipe fully into it. Use the crimping tool to crimp the ring near the fitting to hold it firmly in place. To connect the pex with the drain line, use a coupler to connect and insert a crimping ring over it.

Can You Bury PEX crimps?

The PEX crimps are often made of copper, which is the primary reason they are not conducive to burial. The biggest concern when burying tubing and fittings is how extreme temperatures, particularly freezing conditions, affect their overall functionality.

Can You Bury PEX tubing?

Although you can generally bury PEX tubing, some tubing types will have a longer lifespan than others underground, especially when used to transport water in freezing conditions ( source ). PEX-B is the first choice for burying due to its higher bursting pressure and reduced issues with leached chemicals.

Can Sharkbite Fittings be Used Underground?

As opposed to PEX crimp fittings, Sharkbite fittings are suitable for burial as professed by the company and supported by The International Association of Plumbing and Mechanical Officials ( source ).

Why are PEX crimps not buried?

The biggest concern when burying tubing and fittings is how extreme temperatures , particularly freezing conditions, affect their overall functionality.

Why is PEX C so hard to work with?

It is, by far, the most difficult PEX tubing to work with because it is incredibly stiff. This means the tubing is more prone to kinking and cracking when exposed to freezing conditions. Since the goal is to bury the tubing, using PEX-C would most likely require frequent repairs due to damage and bursting.

What is the best PEX tubing for burial?

This is the second-best PEX tubing option for burial, behind PEX-B.

Why put PEX tubing in sand?

Embedding the tubing in the sand once it is buried can help prevent damage from rocks and soil. Bury the tubing below the frost line to prevent water from freezing in the pipes . That being said, here are the three types of PEX tubing, two of which are ideal options for underground systems.

Why is PEX B used for burying?

PEX-B is the first choice for burying due to its higher bursting pressure and reduced issues with leached chemicals. Some individuals are wary of using any type of PEX tubing outdoors because it degrades under UV light. This means that if the tubing is exposed to the sun, it will break down much faster.

How much does PEX tubing cost?

PEX-A tubing typically costs quite a bit more than PEX-B tubing at an average cost of $3.50 to $7.50 per 10-foot piece .

Can PEX Pipes Be Used Outside?

PEX piping is NOT recommended for outdoor use unless it is buried or protected somehow such as wrapping it in insulation. The reason is because it deteroriates when exposed to continuous UV rays (sunlight). For outdoor piping we recommend using Copper pipes.

What is PEX pipe?

PEX pipes, also known as Cross-linked polyethylene pipes are commonly used for residential water lines but can also be used for sewage, chemical transport, heating and cooling systems and more. It’s used as an alternative to PVC, CPVC or copper tubing. It’s also known as PEX tubing.

How long has PEX tubing been used?

The durability and flexibility of PEX tubing has been tested for over 50 years. Although PEX has only been approved in the USA since 2010 (California was the first state) it has been successfully used in Europe since the 1960’s.

How to contact Atlanta plumbers?

If you are considering using PEX pipes in your residential or commerical property, call the Atlanta plumbers – Atlantis Plumbing today at 770-505-8570. We are available 24 hours a day, 7 days a week.

What happens if the temperature falls below 20 degrees Fahrenheit?

Generally, if the temperature falls below 20 degrees Fahrenheit ice will form in water lines and pipes will freeze.

Can PEX tubing be used under tile?

Yes. The high density polyethylene (HDPE) material in PEX is durable enough to tolerate being buried in concrete. Most often, PEX tubing is used in radiant heating under tile floors. Of course, there are exceptions depending on the chemistry of the concrete being used.

Is PEX tubing a good choice for frost?

It should be buried below the frost line and best if bedded in sand or stone dust. The Advantages Of Using PEX Tubing are: It’s very flexible. It comes in long coils so it requires less fittings. It tolerates temperatures well. It’s less expensive than PVC, CPVC or copper.

What is the meaning of "back up"?

Making statements based on opinion; back them up with references or personal experience.

What is the enemy of PEX?

PEX’s primary enemy is UV light so make sure to protect it if it exits the earth to supply the spigot.

Can you use PVC as conduit?

Best practice would be lay PVC as conduit and put the PEX inside it. Any bends would be Schedule 80 sweep 90s. You could use Sch 40 for the straight sections or use Sch 80 entirely. You would have to find out which size to use.

Can animals chew PVC?

One plumber of my acquaintance advocated using polybutylene (PB) which comes on rolls. He also said chewing animals will not chew into P VC.

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.

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.

Do PEX Pipes Burst or Freeze?

The flexibility of PEX tubing means that the pipes experience expansion if water freezes in the lines. Once the water thaws, the tube will contract back to its original shape. This ability makes PEX pipe freeze-damage resistant. However, that’s not the same thing as freeze-proof. For example, if the temperature drops below 20℉, water will freeze in the pipes.

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.

How to run PEX pipe in mechanical room?

1) splice underground and continue the trench, to come up vertically into the mechanical room. the vertical part will require some sort of "heat tape" as it will be in unheated space. 2) come up into the unheated space right where i am now wiht the end of the PEX sticking up a few feet, and run it along my drainage chase and into …

Can you use PEX underground?

I wouldn’t use PEX underground. Use 200psi Poly. You can buy it in a 100′ roll. Make the transition to copper or PEX by using a brass 3/4" barbed by thread (MIP) adapter. Then an FIP adapter.

Can you lay PEX in the ground?

Nothing wrong with laying PEX in the ground, they use it here all the time with the noted compression couplings and I’ve never seen a problem with it.

Can plumbers use soft rolled copper?

i agree with previous post. Try to obtain longer run of pex to avoid any fittings. Even when using copper, plumbers use soft rolled no joint copper to avoid fittings.
