1800CAP Spray Head Cap for 1800 Series Sprinklers, 1-Pack

Un-screwed sprinkler mechanism and placed cap on. No issues screwing it on and has worked perfectly! Zero leaking!

I live in a townhouse complex where we still have the original underground sprinkler system layout which has never been updated regardless that updates have been made to retaining walls on either side of our lawns and/or that the lawn edges have been graded to slope to the ground resulting in the sprinkler heads being 1.5 feet in from the outside lawn edge therefore, the outer 1.5 feet is not getting watered & the new turf they installed when slopung the lawn is dying. Although its supposed to be a condo board expense I find it a hassle to get them to agree to purchase what I specifically want so I just invested in mp rotary sprinkler heads and, then used this to cap off the sprinkler head that was no longer watering as needed.I’m happy to say that the water from the center 360 degree adjustable mp rotating sprinkler head valve that I installed waters the entire lawn.

Quando mi è stato montato l'impianto pensavo avessero lasciato i tappi originali, cmq nessun problema visto che ho trovato esattamente il tappo originale, che assolve perfettamente allo scopo :D

I bought 20 on these caps. 18 of them worked perfectly on Rainbird sprinklers. The other 2 leaked badly on Lawn Genie sprinklers. I have never seen this product in Lowes or Home Depot. If you use them on Rainbird they are as easy as screwing on a bottle cap. Just make sure to get the green washer tight in the cap and make sure to clean the groves on the sprinkler. Excellent product. I am very happy with it. Wish I knew about these caps years ago.

Worked perfectly but very expensive for what they are.
