Water inside the tank is gray.
Water pressure is slowing.
Water appears grey or cloudy.
Water pressure is slowing immediately after installation.
Notice: If you have experienced a Boil Alert or require your system to be sanitized, please go to pentair.com/assets/pwsboilalert
for product sanitization instructions.
Solution
Turn the water off and let the tank sit about 30 minutes
to allow the carbon to settle down off of the basket
inside the tank.
If the pressure drops off again, let the system stand for
72 hours. There is air trapped in the carbon bed that
needs to be released from the tank. After 72 hours have
passed, continue the carbon wash by slowly turning the
water supply back on.
You may need to turn the head to tighten it. The tank
head is preinstalled hand-tight, do not overtighten the
head (simply turn it snug).
If the tank is not level, lift the tank straight up six (6)
inches and tap it on the ground until the tank stands
vertically. The bottom of the tank is round and the boot
allows the tank to stand upright.
This is normal with all carbon filters and this will slowly
fade away. The carbon inside the tank can still have air
pockets inside that, when released, turn the water a little
gray with carbon dust. The carbon dust is harmless.
It is recommended that the sediment filter be replaced
every 6-9 months depending on the amount of
sediment present in the water supply. If the system has
been working properly and the pressure is slowing, it
may be time to change the sediment filter. Check the
sediment filter and replace if necessary.
Water may appear grey or cloudy for the first seven to
ten days after installation due to extra carbon dust.
High flow rates such as bathtubs, utility sinks, hose
bibs, multi-headed showers, body sprayers, or anything
that is considered high flow for the first 72 hours should
be avoided. If you suspect a carbon blockage of the top
basket due to a high-flow situation within the first 72
hours of installation, turn off any running water for at
least 10 minutes. This will clear the blockage and you
can resume using water at low or normal flow rates.
