Why do you snake pipe?
Snaking of Pipe: For smaller diameter piping systems (typically < 3" diameter), snaking pipe is particularly important to compensate for thermal expansion and contraction of the piping when installing pipe in hot weather. (This may also apply to larger diameter piping under specific applications and site conditions).After the pipe has been solvent welded and allowed to set properly, it is advisable to snake the pipe according to the following recommendations beside the trench during its required drying time (cure time). BE ESPECIALLY CAREFUL NOT TO APPLY ANY STRESS THAT WIL DISTURB THE UNDRIED JOINT. This snaking is necessary in order to allow for any anticipated thermal contraction that will take place in the newly joined pipeline. Refer to the section on thermal expansion and contractions for additional information.
How deep should a trench be for a pipe?
Pipe for conveying liquids susceptible to freezing should be buried no less then 12" below the maximum frost level. Permanent lines subject to heavy traffic should have a minimum cover of 24". For light traffic 12" to 18" is normally sufficient for small diameter pipe (typically < 3" diameter). With larger sizes, bearing stresses should be calculated to determine cover required. Reliability and safety should always be considered, as well as local, state, and national codes.
How much pressure should I use for backfilling a pipe?
Each soil layer should be sufficiently compacted to uniformly develop lateral passive soil forces during the backfill operation. It may be advised to have the pipe under pressure, 15 to 25 PSI during the backfilling.
What should be removed from the backfill?
The remainder of the back fill should be places and spread in uniform layers in such a manner to fill the trench completely so that there will be no unfilled spaces under or about rocks or lumps of earth in the backfill. Large or sharp rocks, frozen clods and other debris greater than 3" in diameter should be removed. Rolling equipment or heavy tampers should only be used to consolidate the final backfill. Under certain conditions, it may be advisable to have the pipe under pressure during the backfilling operation.
When is thermoplastic piping needed?
It is recommended that thermoplastic piping be run within a metal or concrete casing when it is installed beneath surfaces that are subject to heavyweight or constant traffic such as roadways and railroad tracks. Piping systems must be designed and installed to ensure they can handle anticipated loads. Refer to critical collapse pressure ratings.

Why do we bury pipes?
After all, burying pipes reduces the chance of an accident by reducing falls and falls into pipes as well as preventing sewage from spilling onto private or public property. And if we want to talk about the benefits, we should say that this process can be done without any need for digging up roads or sidewalks. This saves a lot of time and money for construction companies because they don’t have to spend hours fixing everything after pipe ruptures.
How to prevent concrete from leaking?
One solution is to pipe the concrete into the ground before pouring the concrete into the foundation or use a chemical like an anti-foaming agent that will keep air bubbles from forming. Another solution is to pour the foundation first and fix piping later; this way you won’t have pipes sticking out of your finished product or any other problems that come with them being exposed for too long.
What precautions should be taken when burying pipes in concrete?
Pipes can move out of place after the concrete has dried, which could lead to leaks and other issues. For example, when burying pipes in concrete, the safety measure is waterproofing the pipe, making sure it is underground and using a cement mortar.
Is burying PVC pipe a good idea?

You must be careful before you start driving over your yard. One mistake could lead to busted pipes and a broken septic system . Find out more about the safety of driving over the PVC pipes in your yard by reading on.
How does soil react with PVC?
How the soil is packed is what matters most here. When a significant amount of weight is positioned over the PVC pipe, it reacts by flexing slightly. The pipe flexes along its sides in order to support the weight. Those sidewalls will stretch out and move down to keep the pipe intact.
How does PVC react to weight?
When a significant amount of weight is positioned over the PVC pipe, it reacts by flexing slightly. The pipe flexes along its sides in order to support the weight. Those sidewalls will stretch out and move down to keep the pipe intact.
Why does the depth of a pipe matter?
The depth of the pipe burial matters because that will affect how effectively the weight will be distributed. Keep the pipe too close to the surface and it will have to support too much weight. You’re not giving the surrounding soil enough of an opportunity to manage the burden.
How to find the thickness of PVC pipe?
To find out the thickness of the PVC pipe, you have to look at the schedule. A larger schedule number equat es to a thicker PVC pipe, so schedule 40 is preferable to schedule 20. Do note though that you shouldn’t just automatically go with the thickest PVC pipes. The added thickness comes at the cost of the pipe opening becoming smaller.

How deep should a PVC pipe be buried?
All PVC pipes should be buried at least 12 inches below the frost line so they won’t rupture in freezing temperatures. However, where heavy traffic is expected, trenches will need to be at least 24 to 36 inches deep. In some instances where there will be continued heavy traffic, like under roadways, metal or concrete casting may also be necessary. Be sure to follow ASTM Standards, as well as state and local building codes when determining trench depth.
How to store PVC pipe?
Avoid storing your PVC pipe in direct sunlight , which could weaken its tensile strength and cause discoloration. High temperatures may also cause damage to PVC pipes. Instead, store pipes in a cool, dry space, where they will not be crushed by the weight of other items on top of them. While transporting PVC to the job site or installation location, be careful not to drag or dump piping either, as this could result in split ends, cracking, or breaking once installed.
What is PVC pipe?
Polyvinyl chloride pipes, or PVC, are strong and versatile, making them the go-to piping material for many plumbing and construction needs.
