Sprinkler question

 I just added on about six bubblers to three Orbit gear drive lawn
sprinklers.  They have a 3/4" feed at about 50 psi.  The three lawn
sprinklers now don't spray nearly as much.  I took off the guts, and the
filters were not clogged.  I turned down the bubblers so they are just
coming out a little.  The other stations function properly.

Do you think I have a clog, or is that too many to put on one line?  I can
put a pressure reducer on to that leg.  But like I say, I barely have the
bubblers on, and don't think that's enough to drop the performance of the
lawn sprinklers by half.

I'm puzzled.

Help appreciated.

 g'day steve,

could there be a limit to how many head can be run or added to system?
if you add heads in then that effects how well what was there before
works, might need to divide or get heads that deliver at lower
pressure??

or somehow increase the pressure in?

Matthew 25:13 KJV
"Watch therefore, for ye know neither
the day nor the hour wherein the Son
of man cometh"

Mark 13:33 "Take ye heed, watch and pray:
for ye know not when the time is".

and also: Isaiah 38:1&17-18 KJV

1: Thus saith the Lord, set thine house in order: for thou shalt die and not
live.
17: for thou hast cast all my sins behind my back.
18: For the grave cannot praise thee, death cannot celebrate thee: they that go
down in the pit cannot hope for truth.

Have considered a booster pump, as this is a gravity fed/booster pump
situation from a local mountain stream, and a holding reservoir.  Pressure
varies a lot according to use.

My neighborhood is on a water system that is gravity-fed from a
1,000,000 gallon tank up on a hill higher than any house.  The pressure
in my lines is high enough that a hose turned on full will writhe and
snap like an injured snake.

I have drip emitters for three dwarf citrus in large flower pots (about
21 inches across and equally deep).  These emitters are tied into my
regular garden sprinklers.  Despite the available pressure, each emitter
is on a separate sprinkler valve.

For my garden, there are 7 valves: 2 in front and 5 in back (popup and
shrub heads).  There is a separate (8th) valve for the drip system for
my roses in front on the far side of my driveway (seven emitters).  And
there are 4 valves for my hill (rotating heads).  Since emitters have a
much lower flow rate than bubblers, I can run the drip system for the
roses while another valve is open, but I cannot otherwise run 2 valves
at the same time.

All of this is to indicate that the "load" on a sprinkler system must be
balanced even when the available pressure is quite high.

Fortunately for me, the 7 garden valves and the drip valve for the roses
are on a clock.  I don't have to keep running outside to shut one valve
and open another.  I do the 4 hill valves manually, but my hill is
irrigated only every third weekend.

That's typical.


Is "injured snake" some new water company standard?

Your water company like every other US water company is delivering
residential properties no more than about 40 psi, with volume limited
by meter diameter.  Most folks on private wells will have much greater
pressure and volume than what a municipal water company supplies
residential customers... you'd be doing good if your tap can produce
four gallons a minute.  With most neighborhoods on a municipal water
system it's suggested to run automatic sprinkler systems during the
wee morning hours before people awaken for the day, and then to have
no more than 4-5 sprinkler heads per zone.
