HunterSprinkler I2004 I-20 Plastic Gear Driven Pop-Up Sprinkler, 4-Inch

Top of the line item. Would use nothing else, worry free item.

I purchased these to replace some older Rainbird rotors (R50s). These have a nice spray pattern that covers the nearby turf just as well as the distant turf area. The old RB rotors were loud and spun too fast. The old rotors did not have check valves so the water always drained at the end of the cycle. This wasted water and took longer to start up because the line had to fill up with water every time the system came on.Features I like:- many nozzle options- Flostop- slow rotor speed- quiet operation- check valve (saves some water and faster startup time)- easy setup and adjustementsThe Flostop is king. I really like this feature, which helps with nozzle changes, maintenance, system testing. Adjusting the rotors are easy and straight forward, so be sure to purchase the Hunter rotor tool for easiest adjustment. The I20 comes with many nozzle options (1-8 gpm) to choose from, including low angled nozzles and short radius nozzles, which may interest some.One word of caution. Be sure to lower the screw to keep the nozzle in place or it will fly out the rotor and you may never find it again. I forgot on one of them and it flew out into the yard. This resulted in very low pressure and none of the heads popped up and I couldn't figure out the problem until I went to check each head and that's when I discovered I forgot to secure the nozzle with that screw.I've used these rotors for nearly 2 years now, so I would and have recommended this product to others.

It is nice to be able to shut a sprinkler head off

Installed the I20 with check valve so water wouldn't drain out. Works great. However, I turned on the sprinkler and it was just "vomiting" water. Turns out, there is no nozzle in it. Disappointed!

My local lawn and garden stores sells the same unit for $10.00 more. Great price from this company on Amazon. I have about 45 heads on my system and like to keep a couple of spares in case i break one with the lawnmower. Since my system has Hunter, I prefer to stick with the same brand.

Super easy to swap out a busted head. Just do a little digging around the old one, unthread it by hand, then thread in new one (no thread sealer needed). Backfill dirt. Then spend 5-10 minutes messing with the start point, sweep angle, and the spray pattern.

It is a professional grade sprinkler. Great quality. Included a wide range of nozzles so you can install this sprinkler in any number of positions in your landscape. The only downside is that it doesn't come with the adjustment tool to adjust the rotation and water flow...luckily I had one already. You can probably use a correctly sized screwdriver for the rotation and an allen wrench for the water flow.

I have ordered this product before. Everything you need is included and it is simple enough for any DIYer to install. Nice product!

Good product, significantly overpriced

Bought 2. First quite popping up after 1 month. Second would not turn off completely when came time to shut off.
