How do I know if my sprinkler system is self draining?
Depending on the type of drain valve your system utilizes, draining could be truly automatic, or it could be manual, requiring that you pull a few levers to get things moving. One way to tell if your system is manual-draining is if your sprinkler heads have check valves on them.

The most noticeable difference is the shape of the cylinder, which is where the pistons are located.

In a two-stage pump, there is one low pressure (large) piston and one high pressure (small) piston.
