Perflex™ Extended Cycle Filtration System _____________________________________
Troubleshooting (cont.)
Problem Probable Cause Remedy
Short cycles - even after proper
Bump-Drain-Recharge.
Contaminated (clogged) Flex-Tube
braids caused by:
1. Natural accumulation of chemical
deposits (accelerated if chemicals are
fed through skimmer).
2. Running D.E. charge too long with
excessive amount of live algae present
in pool.
3. Operating filter without D.E.
4. Operating too long without D.E. after
starting pump. D.E. must be added as
soon as filter is full of water and pump
is putting out a steady stream.
IMPORTANT - Testing a new pool
plumbing system without adding D.E.
will cause this type of clogging.
Clean tube nest (2 methods)
1. Detergent Cleaning: Remove tube
nest and hose down with forceful stream
of clean water. Soak tube nest in strong
solution of laundry detergent (such as
Cheer) and warm water. Hose down
again.
2. Chemical Cleaning: This requires use
of water and muriatic acid solution (or
filter cleaner-type preparations) to
chemically dissolve contaminates.
Consult your pool dealer for chemical
cleaning instructions.
Opening or tear in one or more Flex-
Tubes.
Replace Flex-Tube.
Rip or hole in diaphragm gasket. Replace gasket.
Worn or loose fitting diaphragm gasket
(chemicals fed through suction lines
may shorten life of this part.)
Replace gasket.
D.E. leaking to pool via the return lines.
Loose bolts on tube nest plates. Tighten bolts.
Caking of D.E. under tube sheet.
Sometimes caused by accumulation of
sun tan oils, hair, or floating particles
that bind together in a clay-like form.
Bump-Drain-Recharge more often and
reduce the use of oils.
Overloaded with D.E. Sometimes
happens when last charge of dirty D.E.
was not properly drained.
Bump-Drain-Recharge with proper
amount of D.E.
Hard bumping.
Filter runs too long between bumping. Bump more frequently.
D.E. leaking back to pool via skimmer
or main drain.
Filter check valve worn or stuck open. Clean and/or replace.
Very dirty water. Bump-Drain-Recharge more often.
Presence of live, vigorously growing
algae.
Add enough chlorine to control this
growth - then vacuum.
Very short cycles when vacuuming.
Presence of alum or flocking agents
which will clog filter.
Vacuum so as to bypass filter. Avoid
using flocking agents.
