ACTION TO TAKE
1. Nozzles failing to spray together.
Check that the diaphragm control valve units
are not over tightened. Slacken all control valve
units and retighten finger tight, The idea of
these units is to allow air to bleed from the

3. Blocked tubes or tank.
Remove diaphragm control valves and nozzle

the water pressure from a garden hose, force
blockage through the system, increasing the
water pressure as necessary.
Reassemble when blockage is clear.
4. Drop in pressure
(4. Drop in pressure… continued)
