Note:
This timer is built with a solenoid valve. Technically, all solenoid valves decrease
water pressure. Restmo also has ball-valve timers that do not decrease water
pressure.
If you are not satisfied with the decreased water pressure, please contact us
directly for more details about ball-valve timers.

Solutions may help
The filter is blocking
by dirt or stones.
Clean the filter or replace it
with a new one.
Hose connection is
cross-threaded.
Make sure the timer is installed
properly and not cross-threaded.
Inlet pressure is not
sufficient to support
watering needs.
Install a booster pump or other
booster pressurizing equipment.
Timer dropped water pressure.
