Schedule 40 pe fitting does not have threaded ends so a slip fitting is needed to join sections of pipe together. Slip fittings will slip right on the PVC pipe and may seem tight, but will not hold water. The connection must be sealed. For a leak-proof seal on a slip fitting, you will need both PVC primer and PVC cement. The primer softens the inside of the fitting, preparing it to bond, while the cement bonds the two pieces together tight.
As an easy alternative to the hassle of primer and cement, HydroRain offers PVC-Lock fittings that are a simple push-fit style that do not require gluing for a leak-proof seal. Another advantage of PVCL is the fittings are removable and reusable. A size specific special release tool is required for removal. Here is a link to our selection of PVC-Lock Fittings.
Another alternative, to creating connections that can be taken apart, is PVC threaded fittings. Keep in mind that threaded fittings are a weak point in any piping system and the working pressure is reduced by 50% when a threaded connection is used. Proper technique is required for a secure leakproof connection. Many manufacturers have differing recommendations for using any chemical aid when joining plastic threaded components. Chemicals, such as teflon and pipe dope can degrade the plastic and increase risk of premature failure. We suggest following manufacturers recommendations. The leak-proof seal of a male and female threaded PVC connection can be made using a thread sealant compatible with the material. The sealant is applied around the male (outside) threads, then the two (male and female fittings) are screwed together, finger tight, then one to two more turns at most. Over tightening can cause stress cracks that will fail!
