Irrigation popup sprinkler head conversion to drip irrigation

Does anyone know if there is a drip conversion head that doesn't require capping off the other heads in that zone?

Guessing you have to cap the other heads in the zone to have enough pressure for a drip irrigation system to work. Not sure it's just an adapter problem.

There are parts at home depot and lowes that could do this, but it's not the best approach. As long as you've got nozzles on everything I'm not sure pressure be an issue. Drip lines require filters to keep things from getting clogged. The bigger issue will be time, drip lines need to run a lot longer than spray heads.

Flow rate. Drippers are very very low flow versus sprinklers. You' might not build up enough pressure in the system to get the advertised flow rate through the dripper. Depends on how the system was designed, how big your pump is, how many heads you have, etc. Also as jkee said, having a dripper on for 5 minutes isn't going to do anything. They're designed to be on for much longer.

I think we should go back to the beginning and ask what your application is instead of assuming that this is the right answer.

This zone has 6 heads so I cannot cap off the other 5 regular sprinklers. I am adding a raised planter bed and wanted to line the raised boxes (blueberries and herbs) with the drip irrigation outlets. It looks like that probably isn't going to work so I guess I will continue to just use it normally.

Also no pump it is just water pressure from the utility.

If you run drip lines, just hook them to a hose until you're ready to add a zone to the regular sprinklers.

I guess I could set up drip lines and run them on a regular hose and hose controller. Would solve the immediate problem. Good idea. I have a 16 zone controller and all 16 zones are full. I am SOL I think on using my existing system.

You can have more than 1 sprinkler timer, you just have to make sure they don't run at the same time. When I was a kid, my parents had a 6 zone in the front and a 6 zone in the back. 4-6 zone timers are cheap enough it isn't a big deal. You could also decide one of the existing lines is unnecessary. When I was a kid we ran a hose out to vegetable garden irrigation off a hose tap controlled by the normal sprinkler timer and hooked sprinklers / drip lines to it that varied from year to year. We had a pretty big garden, probably 1000sq ft.

Running it off a hose timer isn't a bad option for now. You can either use an automatic one or one of the mechanical countdown timers. Just check it periodically, a leak can dump a lot of water pretty close to your foundation and cause problems.

And you want to keep the other 5 heads watering the lawn as before? If that's the case, you really need to have the drips on a separate zone, since the watering times and frequencies will be very different between the drips and spray heads (one ~15 min for drips every (other) day, two ~5 min twice a week for spray, at least around here). If your existing controller is full, a simple timer on a hose works well and is probably the best option (grab a Y-splitter as well, so you can continue to use the hose normally).

I have been thinking of replacing my aging rainbird with one of those new, WiFi enabled controllers. The one I was looking at does up to 24 zones. I would need to run a new control line and electronics out for the raised planter and it is on the other side of where the controller would go though. PITA. Probably at least for now I am going to just use the hose controller. There is a faucet right next to the planter box.

Thanks all!

Looks like a pressure reducer is just a flow restriction. Also that guys definition of a "dripper" isn't what I would call a dripper, that's more of a low flow adjustable sprinkler/sprayer. That could definitely work though.
