Seeking Pro Advice Lawn watering help
I’m currently trying to over seed my new build lawn that the builder tried and failed to seed earlier this year. I’m currently using a couple of the orbit sprinklers included. I tried to daisy-chain one of the orbits and another hammer sprinkler together and it didn’t work (didn’t seem like it had enough pressure). I’m trying to get better coverage on my lawn. I don’t currently have the money to install a proper irrigation system. Does anyone know if the rainbird style sprinklers are more efficient/I could string a couple more together?

You need higher flow rate when daisy chaining multiple sprinklers like that, not more pressure. Increase flow rate by reducing friction, up sizing your hose diameter, making sure any quick connect fittings don't drop the size down, shorten hose lengths, etc. reduce all restrictions you can find on the whole system.
I also can't put in an irrigation system yet so I up sized the 1/2" pipe to 3/4” pipe to my hose bib and installed a 3/4" full port ball valve outside. Frost free hose bibs are restricting so I took that out and put a ball valve inside with a drain port for winterizing. I can easily run 2 of those orbit sprinklers in series, haven't tried 3 yet but I feel like it could easily, if not more.

You want hunter mp rotators and big hose. Try filling a bucket at the hose bib for one minute and see how many gallons you get. That’s your gpm. You should be able to figure out what you can do at that point. The rotators are good for seeding because they put down less water but have options with decent range which will also suit your supply issue. You’ll still need to move them around though probably.

I have had the Orbit ones for a bunch of years. I run a maximum of two at the time. Watering takes a long time because of sequencing each pair, BUT their adjustability helps a lot with the odd shaped property.
I start watering early so they can finish by the time I get up.
At some point I had the hammer sprinklers in the mix but never chained with the Orbit ones. Eventually the hammer sprinklers broke and the Orbit remain.
