PVC (PolyVinylChloride) is the preferred pipe in most sprinkler systems. Its greater strength, the ease of attaching fittings, and high pressure operating capabilities are just a few reasons. Most PVC pipe comes in lengths of 20′ and one end of the pipe has a bell end that can be glued to the next joint of pipe. PVC pipe is also somewhat flexible and can be laid in a gradual curve if necessary.
Some advantages PVC has over other types of pipe are:
- The smooth walls of the PVC pipe means it will have less friction loss than other piping like galvanized pipe.
- PVC pipe is strong and durable despite its lightweight.
- PVC pipe is a non conductor of electricity and is immune to chemical corrosion that affects other types of metallic piping.
- Ease of installation. No threading is required when installing PVC pipe.
- Cost. PVC is more than competitive with other types of piping on the market.
Pros – For me it’s ease of use. If I have 3/4″ and 1″ PVC pipe on my truck and a few fittings, there aren’t many sprinkler repairs that I can’t make.
Cons – Compared to galvanized, poly, and even rainjet piping, there are no cons for PVC.
