Seven Steps to a No-Leak Fit

Take notice of some of the tools and materials list before you begin.

  • An axis-cutting machine is any tool designed to cut plastic, such as a ratchet-type pipe cutter, miter saw, reciprocating saw, mechanical cutoff saw with carbide-tipped blade or wheel-type pipe cutter.
  • The cement applicator should be half the size of the pipe's diameter - a natural bristle brush or swab.
  • Use a solvent cement conforming to the appropriate American Society for Testing Materials standard.

Don’t allow cement to puddle or accumulate inside the system. Solvent cement should conform to the appropriate ASTM standard for the piping system (see the solvent cement manufacturer's recommendations). All-purpose cement isn’t recommended.


Step 1

Cut pipe.

Cut the pipe square with the axis.

Step 2

Remove burrs.

Remove burrs and bevel the end of the pipe 10 to 15 degrees.

Step 3

Dry-fit the pipe.

Dry-fit the pipe. With light pressure, the pipe should go 1/2 to 1/3 of the way into the fitting hub. Don't use pipe and fittings that are too tight or too loose.

Step 4

Apply sufficient cement

Use an applicator to apply sufficient cement into the inside of the fitting. The applicator should be 1/2 the size of the pipe's diameter.

Step 5

Coat the surface with primer.

Coat the surface with primer by applying a full, even coat of cement on the outside diameter of the pipe and to the inside hub of the fitting. Again coat the outside of the pipe. Primer isn’t necessary for CTS pipes, but check with your local plumbing codes.

Step 6

Insert the pipe.

While the cement is fluid, insert the pipe into the fitting hub, giving a quarter turn to ensure full distribution of cement within the joint. Allow the joint to cure prior to hydrostatic testing.

Step 7

Follow the manufacturer's recommendations for set and cure times as well as for primers and cements.


Primers and cements are extremely flammable and may be explosive. Don’t store or use primers or cements near heat or an open flame. Ignition of the solvent vapors caused by spark or flame may result in injury or death from explosion of fire.

Solvent fumes created during the joining process are heavier than air and may be trapped in newly installed piping systems.
When working with cements, primers and new piping systems, provide adequate ventilation to reduce line hazard and minimize inhalation of solvent vapors.


Testing with or using compressed air or gas in PVC / ABS / CPVC / cast-iron pipe or fittings can result in explosions and cause severe injury or death.

Never test with or transport / store compressed air or gas in PVC /ABS / CPVC / cast-iron pipe or fittings.
Never test PVC /ABS / CPVC / cast-iron pipe or fittings with compressed gas or air over water boosters.
Only use PVC / ABS / CPVC / cast-iron pipe for water or approved chemicals.
