I use a plastic tool tote to carry my sprinkler tool kit. I keep an assortment of spare sprinkler heads, nozzles, riser nipples and essential tools in the kit. All of the sprinklers should be inspected in the spring when the system is first turned on. Make periodic checks throughout the season to make sure no heads have become broken or damaged. A dry spot in the lawn or bushes is an indication of potential trouble. A swampy area is also a concern. A single broken head can affect the performance of all the heads in the zone.
A small stainless steel shovel works best for digging out around sprinkler heads.
When a head has broken loose, the riser nipple is usually damaged. A nipple extractor makes short work of removing the broken piece.
A 16 in 1 tool can handle all the adjustments and repairs to the sprinkler heads.
This is a ratcheting PVC pipe cutter, primer, and cement. Do the job right and use both the primer and the cement. You don’t want a joint to come apart underground somewhere. Read and follow the directions on the cans. These products usually have a shelf life of 3 years. The cement will probably gel within a year of opening the can. Because of this, the home user is better off buying the smaller 2 can kit that includes both primer and cement.
My favorite sprinkler tool is a remote control. I can turn zones on and off out in the yard where I am working. It is a real pain to run back and forth to the garage or basement to operate the sprinklers while making repairs. Sprinkler timers with remote controls are very affordable.
