A) It is very common for the main and brine
pistons to need replacement after 5-10
years of use. The valve will get stuck
trying to complete a regeneration cycle.
Very often this occurs at the beginning of
the “brine rinse” cycle. The timer motor
may stop at this point also. The motors
are made to stop instead of forcing the
valve (which results in gear damage).
A) Replace the main piston and the brine piston
assembly. If the valve is on a chlorinated water
source or over 10 years old, it’s a good idea to
replace the main piston seals at the same time.
On rare occasions the timer motor may also
need to be replaced. Try the pistons replacement
first, this usually does the trick.

A) There are a number of reasons why this can occur. To test if gears need replacement, remove
the meter dome, turn the cable by hand and observe the small white gears inside. You should
be able to make them turn with normal finger pressure. They should also continue to spin for
a moment after you stop applying pressure. If you cannot turn the white gear, you need to
replace the “meter cover”.
Most residential models use the standard range (0-21, i.e. 2,100 gallons) black plastic meter
cover and matching program wheel on the control. There is an extended range (0-55, i.e. 5,500
gallons) that is also available. Fleck also makes a brass 1” meter. This would only be found on
large commercial applications.

Another problem that can occur with the Fleck 5600 Econominder (metered) valve. The gears inside the meter dome cover fail.
This can be due to a number of reasons.
The way to tell if this part needs replacement is to remove the meter dome, turn the cable attached by hand and observe the
small white gears inside. You should be able to make them turn with normal finger pressure. They should also continue to spin
for a brief moment after you stop applying pressure. If you cannot turn the white gear, you need to replace the “meter cover”.
