What causes a sprinkler clog?
Most sprinkler clogs are caused by a buildup of mineral deposits (from rust, calcium, magnesium, or iron), dirt, and/or debris filling up the sprinkler head or the hose/plumbing attached to it, which stops the flow of water.

Cancel that clog!
Now that we’ve established the source of your clog, it’s time to get rid of it! Review your owner’s manual, and let’s get to work!
Level 1: Minimal buildup
If you notice some a light layer of dirt or debris on your sprinkler head (like after mowing the lawn), wipe it off with a microfiber towel.
Level 2: Moderate buildup/mineral deposits
For dirt or debris that’s a bit caked on, use a toothbrush to get in there dislodge any foreign object before wiping it clear with a microfiber cloth. Use compatible solutions to help break things up, as needed.
Level 3: Moderate mineral buildup
To get rid of mineral deposits, keep the microfiber towel and toothbrush, and grab gloves, a bucket full of warm water, and a cleaner designed to remove rust, calcium, and/or other mineral buildup.
Per instructions, dilute the cleaner with warm water only in an area with great ventilation. Remove the buildup-covered sprinkler heads and dip into the cleaner/water solution before using the toothbrush to scrub away any mineral deposits. Wipe with microfiber cloth as you go to check progress.
If your sprinkler head is designed for it, submerge it as needed to make it easier to clean. Once it’s clean, spray or submerge it in cold water before wiping for a final check with a new cloth and reattaching.
Pro Tip: Whenever you clean the sprinkler head and its related parts, check for damage. Noticing a need for repairs early can help you save water, money, and time.
Clear your sprinkler heads biweekly, and check your sprinkler system’s plumbing at least once a month to make sure everything’s in working order.
Look at that – you’re a sprinkler head de-clogging genius!
