F76S Water Filters and
MV876B Automatic-Backwash Controls
The F76S is a high flow capacity water filter used at point-of-
entry (POE) to remove sediment and debris from residential or
commercial water systems. Used as a prefilter, the F76S
protects elements of the water system, including specialized
treatment devices such as taste/odor or reverse osmosis
(R/O) or other common fixtures and appliances. The flow,
filtering capacity, and ease of cleaning make the F76S the
ideal filter for the most demanding applications.
The MV876 Automatic-Backwash Control is available as an
accessory. This control is fitted to the drain valve and is
programmed by the user to automatically perform the back-
wash function according to the desired interval.
Built-in backwash impeller provides efficient cleaning
with supply pressures as low as 22 psi.
Increased flow capacity on 1/2 in. to 1-1/4 in. models
provides lower pressure drop.
Robust backwash mechanism.
No shut-off or disassembly is required for cleaning.
During backwash, the F76S continues to supply
filtered water without interruption through a secondary
Memory ring indicates when the next manual
backwash is due.
MV876B1018 bayonet fitting simplifies upgrade to
16 field-selectable backwash intervals (from every four
minutes to once every three months) on the MV876B
eliminate need for external timer.
Connections for external control on the MV876B
provide for use in automated systems and differential
MV876B can be turned manually to initiate backwash.
Battery (AA) backup to insure completion of backwash
cycle in spite of power loss.
