How to install polyethylene pipe

To maintain proper performance, you'll need to take care in assembling the bell and spigot. Lay your pipe in place and position it carefully, then clean out the bell and spigot ends. Remove the protective plastic from the gasket, then apply an appropriate gasket lubricant to the bell and spigot ends of the pipes using a clean rag or brush, taking care that the lubricated sections do not touch the ground or become dirty.

Using a nylon sling and a backhoe, line up the two ends and pull the spigot squarely into the bell, maintaining a low insertion angle of 1. If you must push on the bell to assemble the pipes, it's vital that you use an assembly installation stub to protect the bell's integrity. You may need to adjust the length of some pipes to meet your project's needs, which should be completed according to your material's pocket installation guide. Once everything is in place, it's time to backfill.

Though there are many materials available, refer to the pocket installation guide to ensure you're using an appropriate backfill material for your needs. Other materials, including native soils , which are not listed as a class 1, 2 or 3 material generally should not be used. Knife the backfill material underneath the pipe to prevent voids and help ensure even backfill placement. This also helps prevent the pipe from shifting during backfilling. In addition to the rig and pipe, there are other tools and equipment needed for underground pipe installation.

Chapman Electric carries a full line of gear to make sure your project is a success. These are sometimes called birds, and are used when installing lines into duct. The line is attached to the carrier, then the carrier is inserted into the duct, where blowing is used to move the carrier and line through the duct.

Duct Plugs. Seal-Off Kits. Seal-off kits insert into duct, then twist tight to create a vapor-tight barrier. Seal-offs are installed to prevent explosions where a spark producing devices, like a breaker, could possibly ignite the gasses inside the conduit. Tracer Wire. Tracker wire is also called locating wire. When plastic pipe is laid in the ground, tracer wire is installed along the top of the pipe.

Once buried, the tracer wire allows pipe location equipment to detect the metal in the tracer wire. Turn the wrench until the outer locking nut is loose but do not take apart the fitting, advises PlumbingSupply. Slide an end of a piece of poly pipe into the loosened side of the compression fitting. Slide the pipe until you feel the pipe bottom-out inside the fitting.

Turn the locking screw clockwise with the adjustable wrench until it is tight. A tight locknut does not allow the pipe to move in the fitting body. Loosen the second locknut with the adjustable wrench.

Slide the loose end of a second piece of pipe into the open side of the fitting. Turn the locknut clockwise to lock the second piece of tubing in the fitting body.
