Regular backwashing is a very important part of keeping your pool
clean and maintaining an effective filtration system. For the Hayward
Pro-Grid series, it is a simple process and can be completed in just a
few steps.
First identify the size of your filter by looking for
the model number on the chart which is displayed on the side of the
filter (See below). This information is needed to determine how much
D.E. to replace back into the filter once backwashing is complete.
Model # | Effective Filtration Area | D.E. Required
D.E.2420 24 ft. 3 lbs.
D.E.3620 36 ft. 4.5 lbs.
D.E.4820 48 ft. 6 lbs.
D.E.6020 60 ft. 7.5 lbs.
D.E.7220 72 ft. 9 lbs.
Step 1: Turn off the pump from the circuit breaker or timer box.
Step 2: Open up the waste valve and/or roll out the waste line.
Step 3: Push
down and turn the multiport to the BACKWASH position. Turn the pump
back on and watch the eyeglass as the dirty D.E. water passes through.
Leave it running on backwash for 2 minutes.
Step 4: Turn the pump off again, move the multiport to the RINSE position and turn pump back on. Leave it running on RINSE for 1 minute.
Step 5:
Repeat steps 3 and 4 until eyeglass is showing clean water running
through it while on backwash. This means that all of the D.E. has been
washed out.
Step 6: Shut off the pump once again, turn the
multiport to the FILTER position and turn the system back on. Use the
information provided on the chart to determine the proper amount of D.E.
and add directly into the skimmer while filter is running.
How to backwash a Hayward Per-Flex Bump Handle Filter:
Backwashing
the Per-Flex filter is similar to the Pro-Grid filter except it
contains a bump handle which is used to loosen up the dirt and D.E. from
inside the filter. This allows for greater flow and allows it to drain
out. Once again, use the chart (see below) to determine the right amount
of D.E. to add once backwashing is complete.
Model # | D.E. Required
EC-40 4 lbs.
EC-50 5 lbs.
EC-60 6 lbs.
EC-65 6 lbs.
EC-75 7 lbs.
Step 1: Turn off the pump from the circuit breaker or timer box.
Step 2: Open up the waste valve and/or remove drain plug.
Step 3: Push
the handle up and down slowly about 20-30 times. This is known as
"bumping" this type of filter. Turn the pump back on and watch the dirty
D.E. flow out through the waste line. Leave it running for about 2
minutes like this, or until the water being pumped out is clear again.
Step 4:
Turn the pump off again, close the waste line and turn pump back on.
Leave it running for about 1 minute or until the filter fills back up
with water.
Step 5: Repeat steps 3 and 4 until only clean
water is running out through the waste line. This means that all of the
D.E. has been washed out.
Step 6: Shut off the pump once
again, close waste valve and/or reinsert drain plug and turn the system
back on. Use the information provided on the chart to determine the
proper amount of D.E. and add directly into the skimmer while filter is
running.
When to Bump vs. Bump and Backwash:
You
can use the bump feature in between backwashes to boost the filter's
water flow and regenerate filtration without having to replace the D.E.
like you would with a full backwash. To bump, simply turn off filter
system and then move the handle up and down without opening any waste
lines or valves. This will reposition the D.E. inside the filter,
regenerating the D.E.'s effectiveness. Turn filter back on.
How to Backwash Sand Filters:
Backwashing
a sand filter is very similar to backwashing a Hayward Pro-Grid D.E.
filter except there is no replacement of D.E. or sand afterward. The
sand should be replaced about once every 5 years. After 5 years, the
sand loses its filtration efficiency and the filter cycle must run even
longer to get the same effect.
Step 1: Turn off the pump from the circuit breaker or timer box.
Step 2: Open up the waste valve and/or roll out the waste line.
Step 3:
Push down and turn the multiport to the BACKWASH position. Turn the
pump back on and watch the eyeglass as the dirty water passes through.
Leave it running on backwash for 2 minutes.
Step 4: Turn
the pump off again, move the multiport to the RINSE position and turn
pump back on. Leave it running on RINSE for 1 minute.
Step 5: Repeat steps 3 and 4 until eyeglass is showing clean water running through it while on backwash.
Step 6: Shut off the pump once again, turn the multiport to the FILTER position and turn the system back on.
