Rain Bird1800 45 PSI Pressure Regulated Spray Head with Seal-A-Matic 4 in. | 1804-SAM-P45

Replacement heads were good quality and worked well after installation.

I liked that it stops water from dribbling out after being shut off. What I don't like is how difficult it is to adjust water flow with the tiny screw on top of sprinkler. I also found the pattern adjustment is also difficult to adjust.

I had 1 sprinkler zone that was on a small slope... just enough that at the end of each cycle the last sprinkler head would leak all of the water still within the pipe. This resulted in several gallons of water running down the street. I was looking at putting in a check valve, but this sprinkler head was much easier and a very good fix. It works great and was easy to just change out the existing sprinkler - moving the spray nozzle to this new head - and not needing to dig up the pipes to install a check valve. Would definitely buy again if I have another area that drains.

My sprinkler system hadn't had maintenance in some years and it showed. I raised all the sprinkler head to the right height only to find out that, 3 of them had a leaking problem. with these sprinkler heads and having the Seal A Matic with it worked perfect. My lawn no longer looks like a swamp.

Worked as expected

While the system is running everything works great, I couldn't be happier. I have Rain Bird R-Van nozzles installed on all these heads. This would be a 5 star review if the Seal-A-Matic function was included or worked as advertised. Rain Bird claims the valves trap water with up to 14 feet of elevation change. I have about 6 feet of elevation change in one zone and after shutoff a large amount of water drains out of the lower nozzles wasting water and causing a mess of erosion. I also tried Rain Bird HE-Van nozzles, same leaky situation. There are other Rain-Bird heads in the lawn that don't leak, perhaps I was sent a different product than advertised. If you have any slope in your lawn I'd look elsewhere for this product.

This product was well packaged & delivered on time. Very easy to install, works well & had a nice card/message in it.

No more low point sprinkler leaks.

A little exspensive but works good to stop back flow

Easy to install and works great!

Good product but slightly overpriced
