Not only must the sprinkler head be low enough to avoid damage from mower blades, but a uniform head height also ensures the most accurate spray pattern for the lawn.

There should be plumber’s tape or pipe thread sealant on the riser, which is used to fill any excess space between the male threads of the riser and the female threads of the sprinkler head, lowering the chance of a leak. If the sprinkler head riser comes off the water line with the sprinkler head, detach the two parts carefully. Unscrew the sprinkler head from the riser by twisting counterclockwise. The sprinkler head sits on a small pipe, called a riser, that connects the head to the water line. If the exact specs of the sprinkler are still unclear, bring the old head to the store and compare it to new heads, consulting an experienced store employee for advice. New sprinkler heads can be bought at local home improvement stores or online. Failing this, reference the brand and part number on the manufacturer’s website to find the needed specifications.

The next specifications to identify are the inches-per-hour (iph) or gallons-per-minute (gpm) delivery rate, the spray pattern, and the throwing distance. The replacement head needn’t be the same brand as the previous head, but it must be the same type. Fortunately, the top of the existing sprinkler head should contain all the information needed to find a new head that matches.Ĭheck whether the current sprinkler head is a pop-up or impact sprinkler head pop-up heads must be further identified as stationary, rotor-driven, or gear-driven.
