Drip irrigation systems usually have
no moving parts other than the valve in the timer. If you have a
good clean source of water and always use a 150 - mesh filter, your
drip irrigation system will require very little maintenance.
Small drips at the pressure regulator (PR2) or anti-syphon valve (V4) are normal and may be ignored.
Whenever you add new tubing to a drip irrigation system,
turn on the water and flush the tubing before you install drippers
That way any
the tubing is washed out and cannot plug small openings in drippers.
If you take the care to make sure that there are no dirt or plastic
shavings in the system tubing at installation, it will pay off
by reducing the time to troubleshoot and repair later.
At the end of the summer, take the end stops off all tubing and
flush until the water runs clear. If you are using well water that
may have fine silt, try flushing each month. If the flush water is
clean, put off flushing for two months. If the flush water is still
clean, flush only at the end of the season.
Use the same procedure with all filters. Remove the filter
body and check the screen at the end of the first week. If the
screen is clean, check
month. If there is no dirt at the end of a month, then you may only
have to clean the filter once per season.
Once a week, walk along your drip irrigation system when it's on
and look to make sure that water is flowing at each dripper. If a
dripper is not working, replace it. If an entire section of the circuit
is not dripping, look for a kink in the mainline tubing. It's simple to replace a section of tubing by using two barbed couplers (FB4) and a length of new tubing.
