Installed a second kit in my back yard with 2 additional R-VAN-SST heads with 1800 series bodies and everything works great. RVAN’s shoot about 16’ which is enough for what I need. I needed 30 extra feet of 1/2” tubing for the additional heads. Bought the additional parts I needed from Regency Irrigation for $40. I've also played around with some different nozzles instead of the R-VAN-SST and it hasn't affected my pressure. Took 2 of us about 7 hours for layout, testing, trenching by hand and installation. Very happy with my setups. Used hose clamps on all connections for long term assurance of no disconnections and needed some teflon tape on the connection between the tubing and quick connect in ground 90 to stop a small leak. Also drilled a hole through the in ground manifold lid to leave the hose connected and the manifold relatively closed up.
I installed this system in my front yard May 24. Installation was straightforward, hardest part was trenching by hand. Spaced the sprinklers about 18'-20' apart and I have good overlap and full coverage of my yard. Even had to shorten the throw distance on the 4 heads. Only leak I had was where the 1/2" tube connects to in the inground quick connect adapter. I had bought hose clamps for all the connections anyways to prevent potential future in ground disconnections so once I tightened it up and used a bit of teflon tape it was fine. 90' of hose was just enough, I had 3 feet leftover. Layout, testing, hand trenching and install took 2 of us 6 hours. We used a lawn edger to cut through the sod in a V, a small garden spade, square edge spade shovel and the hook end of a crow bar to trench. Dug down approx. 6 inches.
**If you try to open up the range on the sprinkler heads too far with the screw on top, the blue nozzle will shoot out so be aware. Easy to put back in if you can find it but they are small.**
I've connected the system to an Insoma Wifi water timer also from 鶹 https://a.co/d/eH3WpWt and scheduled it to run 3 mornings per week. My GPH measure right around 6 and my system has adequate pressure for all 4 heads to work great. The system isn't complicated so if you follow the instructions it will work great for you.
I will be installing another kit in my backyard and will try to add 2 more R-VAN-SST heads with 1800 series bodies for some narrow sections of grass. If that is too many I will split into 2 zones and run off a dual zone Insoma timer. Renting a gas trencher would make this job really easy but also double the cost of the project.
