iScaper Rating 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… Continue reading PVC Schedule 40 Pipe

Funny Pipe
iScaper Rating iScaper rating – 5 stars ★★★★★ Swing pipe, funny pipe, 1/2″ sprinkler head tubing, and flex pipe are a few of the names for this tubing. The word I would use is fantastic. Before funny pipe came onto the market the only way to reposition sprinkler heads was a tedious exercise of pipe… Continue reading Funny Pipe
Flow, Velocity, & Friction Loss
iScaper Rating The volume of flow in a sprinkler system is measured in gallons per minute (gpm) in the US, and in liters per second (L/s) metrically. The velocity of flow is measured in linear feet per second (ft/s), meters per hour (m³/h), or liters per minute (l/m). Flow in pipe is always accompanied by… Continue reading Flow, Velocity, & Friction Loss
Polyethylene (Black Plastic) Pipe
iScaper Rating Common terminology for this pipe is Poly pipe. I don’t see this pipe much anymore in sprinkler repairs. It is usually installed in yards of older homes from the 1950’s – 1970’s. Poly pipe has low pressure ratings around 125 psi compared to PVC pipe of the same size which is rated… Continue reading Polyethylene (Black Plastic) Pipe
Sprinkler Valve Wiring
In automatic sprinkler systems, there is a controller/timer that is usually located in the garage. The timer sends power to individual valves in the yard and tells the valve to turn on and water a specific sprinkler zone. This is all done with low voltage power outputted by the timer. In everything you read it… Continue reading Sprinkler Valve Wiring
Static and Working Water Pressure
Static pressure is the pressure when water is motionless. In a closed level piping system the static pressure is the same at every point. There are two way to create static pressure, by elevating water in tanks and reservoirs above where the water is needed and by utilizing a pump. Pumps can be used to… Continue reading Static and Working Water Pressure
