How do I determine if I can add one more sprinkler head to an existing residential irrigation system?
Question:

One of the things I do to determine if I can put another head on is, push down on the head, if you can do it easily, then you can't add a head. If it is hard to push down, then it should be OK. You can also change the nozzle size in most heads. If you lower the output and put another head on, then just turn the time up on that zone to compensate for it. It isn't always good to add another head, depending on the pressure, flow you use, and flow you have available.
As long as all the zone seems to be working properly and with good pressure one more is usually possible.
If you are on a well .. does the pump stay on all the time when the zone in question is on? I believe the goal is for the pump to remain on when the zone is on.
Before you dig a long trench maybe try extending a short way add the sprinkler and see.
The person below me is right except one detail.. I'm on a private well with a 2.5 hp pump on a 4 inch well with a 1000 gallon holding tank.. I can run more then 6 on a zone and blow water 50 feet with ease. it depends on your water source.
I also owned a house in the past that had a well and I couldn't run 2 on a zone.. It had a 2 inch well with a weak above ground pump
Turn on the desired zone of your system. Count the number of heads that are active in that zone. Typically there should be no more than 6 active heads in a system running on municipal (City) water with good flow rate. Less if your on a private well. Look at the stream / amount of water and gage the pressure visually if you don't have an actual gage. Chances are good you can add one head to the line by tapping into the closest available existing head or line.
