Your Zoeller Pump Company Recirculating Media Filter (RMF) is
one component of your onsite wastewater system. Your system
consists of a primary treatment device (septic tank), secondary
treatment device (Zoeller Pump Company RMF), and a soil distribution
component (gravity or pressurized leach lines or a drip field). Your
recirculating media filter requires periodic maintenance. Please
read the maintenance instructions and be sure that each procedure
is accomplished in the proper time frame. These instructions also
include guidance for septic tank maintenance. These maintenance
procedures should be carried out by a well-trained professional
onsite service entity.
Input Inspection Schedule
Residents of every home discharging into an onsite system need to do
an annual inspection of inputs to their onsite system. This includes
organic (non-water) as well as hydraulic (water use) wastes. Annual
home inspection includes:
1. Review original “Septic System Do’s and Don’ts”. Note any
changes in household habits and make corrections as needed.
2. Inspect all faucets and toilets in the house and make sure they
are not leaking.
Septic Tank Maintenance Procedures and Schedule
Each septic tank requires periodic maintenance. Maintenance
includes:
1. Inspections need to be done twice annually. Riser cover must
be removed, septic tank must have sludge level recorded and
scum layer observations recorded. If the sludge layer is within
12 inches of the bottom of the effluent filter, the tank should be
pumped. This will likely be every 3 to 5 years for most homes.
2. Septic tank effluent filter can be removed and cleaned with
each septic tank inspection. The Zoeller Pump Company WW1
Filter (170-0078) filter body is removed and the filtered material
held by the filter is rinsed off the filter back into the tank. The
outer element which provides bypass protection needs to be
cleaned and can be removed after replacing the inner element.
Simply withdraw the whole inner and outer element as a unit,
which is the reverse of installation. Disassemble on the surface
and rinse any filtered material into the septic tank.
3. Inspect all baffles, risers and covers. After inspections, secure
riser lid with tamper resistant screws or lock.

Maintenance Procedures and Schedule
Each recirculating media filter requires periodic maintenance.
Maintenance includes:
1. Annual cleaning of the lateral effluent distribution network.
Riser lids for each lateral (located within the media filter) must
be removed and end caps of each lateral located and removed.
Each lateral needs to be brushed with a bottlebrush and flushed
by manually activating the dosing pump.
2. Any cleanout risers that have been damaged or buried need to be
replaced or brought back to grade.
3. Inspect buried horizontal fence material annually. Horizontal fence
material must remain in place to prevent surface access to liquid
being treated.
4. Weeding may be necessary from time to time.

Recirculation Chamber Maintenance Procedures and
Schedule
Each recirculating chamber requires periodic maintenance; 3 months
after start-up and annually thereafter.
1. The dosing chamber should be inspected annually.
Power needs to be shut off at the breaker for this inspection.
2. Riser and lid integrity needs to inspected
3. Electrical connections need to be inspected for water and corrosion.
Repairs need to be made when corrosion is found. The use of
watertight wire nuts is required.
4. Float control operation needs to be inspected. Any hindrance to
float movement must be corrected.
5. Excessive scum and sludge in the pump tank must be removed.
Electrical Components Maintenance Procedures and
Schedule
Each electrical component must be inspected annually.
1. Be sure each panel has a wiring diagram included.
2. Inspect panel for corrosion and obvious problems such as water
or odor in the panel.
3. Note pump cycle and hour meter readings. These should be
recorded in the panel and in the technicians log.
4. Read voltages and amps and compare to start-up.
With pump power on, float operation must be confirmed. Using a plastic
rod, floats can be moved up or down and on/off and alarm switching tested.
