This module shows you how to depressurize,
remove and reinstall a filter cartridge.
The symptoms are that the cartridge needs
to be replaced.
Pentair offers a wide variety of filter cartridge
housings.
Periodically, the cartridge needs to be changed.
We recommend whenever you notice a pressure
drop or a minimum or once per year.
This procedure shows our 3-G housing.
Yours would be similar.
You begin by shutting off the water supply
to the unit.
You then move to the filter housing, trying
to identify the pressure relief button on
the top.
Your unit may not have this.
You press down on the pressure relief button
to relieve any air or water pressure.
Press and hold until the water or air stops
escaping from the unit.
You may then release it, and we can move on
to removal of the sump.
The sump can be removed using nonmetallic
tools.
Pentair offers a full range of filter wrenches
to fit all of the different sizes of housings.
If you do not have one of these, it is acceptable
to use a band-style wrench, making sure that
all components are nonmetallic.
Metallic items will damage sump.
When you are removing the sump, you may want
to have a bucket or other collection item
underneath, as the unit will be filled with
water.
Once you have the sump removed, you may remove
the dirty filter cartridge and dispose of
it.
You will then want to pour out the remaining
water from the sump.
Once the sump is empty of water and the cartridge,
you then want to clean it.
Using paper towels, but no chemicals, you
will wipe down the inside of the housing.
We can then move on to the O-Ring.
We remove the O-Ring in order to make sure
that it is properly lubricated.
We want to make sure to not use any petroleum-based
greases or sealants.
Only silicone greases should be used.
A small amount is applied to the O-Ring and
then placed back into the housing.
At this time, to disinfect the system, it
is appropriate to put in approximately an
ounce or a capful of bleach.
We then unwrap the cartridge, making sure
to dispose of the plastic and the outer wrapper.
We center the cartridge into the bottom of
the housing, making sure to engage it on the
cup at the bottom.
Once it is engaged, we can then put the housing
sump back onto the cap.
Once we have secured this, we make sure it
is snug and only use hand pressure.
Using a wrench will only make it harder for
you to remove it the next time.
We can now turn on the water supply.
The next step is to turn on a faucet in the
home in order to relieve any air or water
pressure.
We also would want to run any carbon finds
out through the system so it is ready for
use.
We recommend a flush of five (5) minutes.
Good luck, and thanks for watching.
