Perfect fit, easy installation
This was just the thing for an area of my yard that has ground cover, but is mostly shaded on half while the other has full sun with struggling plants. The hardest part of installation was clearing the soil around the pop-ups and making sure the threads were clean before attaching the unit and the Xeri-Caps. With those, make sure the O-rings are included with the caps, and that you screw the caps on good and tight. I finally got the stubborn ones to seal with the gentle use of Channel Locks.

Easy item to do drip conversion
This product does the trick for converting a spray zone to a drip line system. Install is easy and also easy for a homeowner to check the filter monthly. Just leave a little excess in the drip line or use a threaded connection so screen can be removed.

Easy Option to Convert Areas to Drip
The retro kit works very well. It is easy to install and with the two different types of elbow barbs you can run drip line in a number of direction. I have used four of these kits already.

perfect solution when regular sprinkle head sprays too much water where you don't need it
M A on Jun 3, 2018
This looks to be the only way to convert Rain Bird pop-up sprinklers to drip. You must also buy the Xeri-Caps for the other sprinkler heads in the zone.

Hi, Its not clear to me what compression adapter fits on the 1/2" male thread on the 1800 retro. The TEE adapters on the site are all 3/4" female, actually couldn't find a 1/2" swivel anywhere? Could someone post what Rainbird recommends to attach on this 1/2" male fitting?

Looking to use the Rainbird 1800 to replace a Hunter I20 rotor head- can it be done?
A shopper on Nov 19, 2011
BEST ANSWER: The 1800 retro is used to replace any type of sprinkler when converting a zone to drip irrigation; I assume this is what you are doing? You may need an adapter for the ½ inlet on the 1800 retro because the I-20 is ¾”
A shopper on Jul 1, 2016
Does a compression adapter come with this body?
John B on Jul 2, 2016
Can I use this to convert individual sprinkler heads and still have spray heads on the same zone?
Paul T on Mar 26, 2012
BEST ANSWER: You certainly can have a riser retrofitted with this kit and the other sprinklers with regular spray heads on the same zone. The problem you have, though, is the length of time you program for the zone. Usually you would want a drip head to be on a lot longer than you would want a regular spray head. If that isn't the case, then you should be OK with a mix of these heads and regular spray heads.
Does it also fit into the standard 1800 sprinkler body, that is the only one you do not mention it being used for?
Tina V on Jul 11, 2015
BEST ANSWER: It fits into any regular sized body, not the cheaper and smaller pop ups.
Does anyone know if this 1800 Retro comes with the body as well?
A shopper on Jun 19, 2012
BEST ANSWER: Ipurchased this in April 2012...it does come with the sprinkler body.
"Permits convenient conversion to drip tubing when used with compression adapter." - What is a compression adapter and does this mean i need one in addition to convert my sprinkler head to drip with this product?
A shopper on Jun 3, 2016
BEST ANSWER: The Rainbird 1800 retro kit is a replacement sprinkler body that incorporates a swiveling 1/2" MPT (male pipe thread) extension jutting out of internals & the sprinkler cap. Inside is a filter/pressure reducer (30 psi, I think?). The bottom of the sprinkler body has the standard 1/2" FPT (female pipe thread) opening for attaching to your existing in-ground irrigation risers. It's really just an OEM body with added modified cap, & press. reducer inside. Rainbird usually includes a compression Tee with the kit. Tee has a 1/2" FPT opening at bottom that goes onto above-mentioned swivel pipe, and two compression outlet arms to which you can connect standard 1/2" smooth plastic irrigation hose. You will need teflon tape for the threaded fittings, a roll of 1/2" irrig. hose for creating the above-ground supply laterals and then a supply of 1/4" drip tubing and 1/4" barbed connectors to run to each plant's drip head, mister, drip sprayer, etc. (drip heads not incl. and these are site/plant dependent.)
I have a line with 5, 1600 spray heads that are spraying against the foundation of my house. Two provide water to 7 shrubs in a line along the foundation. Three provide water to a line of ground cover about 40 feet long and 1 foot wide. Water is needed in these areas because of a long roof overhang, which keeps water away. However, I am concerned about the amount of water that currently sprays on the foundation. I would prefer to use a drip system, or something else, to water these areas without needing to spray or soak the area directly next to the foundation. What do you suggest? Thank you.
Jerry on Apr 13, 2015
BEST ANSWER: Jerry there are quite a few details to consider that aren't present in the dialog. But in regard to this conversion unit I like them. I have used them often and stock several at a time. In terms of pressure I like to keep it higher out to the point of delivery and these units do that. There is also a unit that is riser oriented with out the filter that I like to use if there are are several points to distribute to . I then use a wye filter back at the valve. You may also want to check out Valvette systems little valve sprinkler inserts they can help hone in radius on sprays. Going to drip on preexisting ground cover can be a challenge but is not impossible. I would stick with an inline. Hope this helps. Go sprinkler warehouse!
Backyard zone has about 12 sprinkler heads... Is there a limit to how many 1800-retro conversion kits I can install in a zone? Is there limit to the length of the drip line per kit?
Lillie P on May 12, 2018
BEST ANSWER: Without knowing the shape of the area you are converting its hard to say. The limit will be on the drip line you choose to attach to the conversion. You can actually run all 12 but that's not necessary. I usually run about 300 lineal feet off of one conversion or 700 if using a tee as the top connection. The last big bed I did was 1500 square feet used rainbird drip tube with 12 inch spacing and ran it off of two heads. just make sure you tube stays within 12 inches of each other or you get dry spots. Don't exceed the recommended run length for whatever drip tube you are using.
can I just swap out the insides of the 1800 rather than the whole body?
A shopper on Jun 15, 2016
BEST ANSWER: Yes you can easily do it. Just take the top off of the pop up that will
hold the "RETRO", take the whole assembly out and insert the
filter and pressure regulator and top part of retro. it can be a 4",
6" or 12" pop up body, as long as the top part fits.

Good luck
does the 1800 come in 3/4 inch female threaded inlet?
sal e on May 27, 2015
BEST ANSWER: No it's a 1/2 inch which is kinda standard. Through the use of bushings you can convert it to accept a 3/4 inch male fitting. I'm not sure if a big box store would carry this pvc part but an irrigation store will.
Will this drip conversion kit's internals work with comparable Hunter brand sprinklers, or is it made specifically for Rainbird sprinklers? If not, does Hunter make a comparable kit to this Rainbird kit? All of my sprinklers are currently Hunter Pro Spray series. I would rather put the internals in an existing sprinkler body than have to dig up the entire sprinkler.
A shopper on Mar 2, 2019
BEST ANSWER: You would take out your existing Hunter sprinkler body and insert this in its place. This screws into the sprinkler main line just as your hunter does now.
I am looking for a misting system for a greenhouse. I would like to mist from around 5' above the ground to allow me to water plants under that height. Any suggestions?
Jim M on Jan 8, 2016
BEST ANSWER: Jim, I used this product to run a drip line off of my main sprinkler line. This reduces the pressure to 30 psi and also
has a filter inside. Off the 1800 retro I ran 1/4' tubing and used a variety of nozzles to water each individual
plant. There are various items to make this work for you. The only reason I needed this part was to branch off the main line and eliminate a separate line for drip or misting plants. You may not need this part.

I just installed the Rainbird 1800-RETRO and I have a significant leak through the swivel fitting. Any suggestions?
