MY SPRINKLER(S) WON'T
ROTATE. WHAT'S THE PROBLEM AND WHAT SHOULD I DO?
This type of problem is often caused by a problem with water
pressure problem that is either too low or too high. Most
water departments (or whoever provides your residential water)
can tell you the approximate water pressure in your neighborhood,
or you can check it yourself with rented equipment. Compare
your pressure to the water pressure recommended for your impact
sprinklers. You may need to make adjustments to bring the
water pressure in line with your needs.
MY PLASTIC IMPACT SPRINKLERS
HAVE STOPPED ROTATING AND I CAN'T SEE ANYTHING BLOCKING THEM.
WHAT SHOULD I DO?
One of our first questions is how many years old or how many
irrigation seasons have your sprinklers operated? It is normal
for impact sprinklers to require some maintenance after about
7 to 10 seasons. As with any moving sprinkler, water pressure
and flow volume play an important role in the rotation of
the heads. Here's any easy way to determine if water pressure
is the possible cause of the problem. If the head is not rotating
back to the left, go to one of the correctly operating heads
on the same zone. Using your thumb, seal off the nozzle where
the water is shooting out. If the non-rotating head starts
to rotate, you may need to recalculate the system's optimum
flow volume. One possible way to solve this is to put smaller
nozzles into your sprinkler heads. Another possible way is
that if you have a flow control valve you can open up the
flow control which allows more water to pass through the valve
to the sprinklers.
WHICH LUBRICANT DO YOU
RECOMMEND FOR USE WITH YOUR SPRINKLER HEADS?
The only lubricant Rain Bird recommends with any of our equipment
is water! Any other lubricant will cause dirt and other debris
to attract and stick to the different parts of the sprinkler.
This dirt can become abrasive and wear out seals causing the
sprinkler to loose performance, stop turning, leak, or even
stop functioning completely. If you're having trouble with
sprinklers that are not rotating, please see the solutions
related to rotation.
