Maintenance Recommendations

LAKOS recommends periodic inspections of the separator to keep performance at an

optimum level.

1. Flange gaskets or victaulic gaskets should be checked for leaks and replaced as

necessary. Gaskets should be replaced at disassembly of separator.

2. Hand hole clean-out: Hand hole should be removed to inspect the collection chamber

for unwanted build up. Inspection should be conducted annually (or when separator is

shut-down for other system service routines), open the hand hole clean-out and

inspect for solids accumulation or unwanted build-up in the separator’s collection

chamber. If necessary, remove excessive debris. Inspect gasket and replace if

necessary. Check purge programming (if applicable) to be sure it is adequate to

remove separated solids; if not, re-set to extend duration and/or frequency of valve

actuation.

3. Pressure gauges: The gauges installed on the inlet & outlet of the LAKOS Separator

help monitor proper liquid flow through the separator. They are NOT indicative of

solids accumulation and should NOT be used to determine when to purge the

separator. Gauges should read a pressure differential loss of 2-15 psi from inlet to

outlet and that differential should remain steady with the flow of water through the

separator. Fluctuations in gauge readings indicate:

a. A change in pump flow – Inspect pump for proper operation and/or

downstream piping/equipment for conditions that could create backpressure

on the system flow.

b. An obstruction in the separator – Internal slots may be clogged by unusual

solids. Use a video scope to examine & remove blockages from internal

slotting. Consult LAKOS if necessary.

c. Gauge blockage – Close petcock valve, remove gauge and check for debris

clogging the gauge port, which could affect an accurate gauge reading.

4. Separator slots should be inspected during facility pipe inspection. Inspection of slots

is recommended when separator performance is suspect. Slots should be checked for

obstruction and wear.

5. Visual inspection of the separator should be conducted at least once a month. Visual

inspection should also include observing the inlet and outlet gauges on the separator.

This inspection will indicate the pressure drop across the separator. The pressure drop

and actual flow rate can be compared to the product brochure to determine if the

separator is operating within its expected performance range. Automatic purge or

manual purge should be checked for leaks and operation. Purge valve seats or

diaphragms should be changed as necessary.
