Rain Bird 1800CAPS Spray Head Cap for 1800 Series Sprinklers

We extended out our deck, which now hangs over one of our underground sprinklers heads. This cap closes it off so that it won’t spray under the deck. The cap was delivered in just one day. It is made well, fits and seals well, and was easy to work with. it was a product that was not carried by either Ace Hardware, nor Lowe’s. We were glad to see it on Amazon. Good product.

Easy install and no leaks. Worked well to cap unused sprinklers

Fit my Rain Bird sprinkler head perfectly and capped off an unneeded sprinkler. Zero issues and easy to install.

The first time I put cap on it popped off with the water pressure. Removed the cap and the sprinkler part it screwed onto. Turns out because of some dirt on the pipe threads I had not screwed it down all the way like it felt I had done. Two things...I wiped down all the thread areas both on the cap and the sprinkler pipe it screwed into. I had pushed the gasket tight down into the cap. I brought it back up so that it circled where it should have, but not pushed down tight into the cap. Screwed it onto the pipe tightly and now it stayed and worked well with no water escaping.

Easy to install to cap our unused irrigation sprinkler heads. There is however some mild leaking when that zone is active.

I've decided not to return this item

There must be more than one size of these. I removed a rotary rainbird head and this was too small to cap it.

I used this on a sprinkler I did not want to use anymore and it has held down the water very well for one year so far. Super cheap and works great and I will buy again if needed.
