Replacing the Media
NOTICE
Your OneFlow
media should be replaced every (3) years.
®
1. Shut off the primary feed supply going to the OneFlow
2. Open up a downstream spigot or faucet to release pressure
in the tank and in the distribution lines before and after the
system.
3. Shut the isolation valves immediately before and after the
tank.
4. Disconnect the unions on the inlet and outlet of the tank,
and then disconnect flex connectors from head.
5. Using a step ladder and strap wrench, remove the threaded
head assembly connection (turning counter-clockwise) and
remove the complete upper assembly including grey-colored
PVC strainer. Rinse these parts in a nearby sink or bucket of
water. Do not drain the tank.
6. Remove the distributor tube with the bottom strainer. Rinse
these parts in a nearby sink or bucket of water.
7. Get a 6ft length of 3/4" sch. 40 PCV and a length of 1" poly-
vinyl hose. The length of hose depends on the distance to
the nearest floor drain. (Both of these can be acquired at
Home Depot or Lowes.)
8. Insert one end of the pipe inside the hose and put the other
end of the pipe into the top of the tank and down into the
media. Put the other end of the hose inside a rice bag and
put the rice bag on the floor drain.
9. Get a garden hose and put it on the open end of the poly
hose to fill the hose and pipe with water. Air will bubble out
of the tank. Once all the air is out of the hose and pipe, you
can start a siphon to remove the media. Put the garden
hose in the top of the tank and turn it on to keep the tank
full of water. Push the pipe up and down in the media to
get it all out. The rice bag will catch the media and allow
the water to go down the drain.
10. Try not to be too aggressive when extracting the media.
You need to take it out in small bites. If you let the whole
pipe/hose fill with media it will plug up. You need to let slugs
of water flush out the pipe as you go.
11. When all the old media is removed turn off the garden hose
and continue to siphon until the tank is about half full with
water.
12. Using the step ladder again, reinstall the distributer tube with
bottom strainer that was removed in step #6. Center the dis-
tributor tube in the bottom of the tank. Keeping any and all
media from entering the distributor tube, carefully pour-in a
new bag(s) of media that specifically meets the replacement
requirement of the tank. For example, an OF1665-75TM
system requires (x1) OF1665RM Replacement Media.
13. Inspect the threaded connection on the top of the tank to
ensure no loose beads of media are stuck to the internal
threads. If visible, wipe away the beads with a damp cloth.
14. Re-attach the head assembly onto the distributor tube and
thread the head assembly back onto the tank. Hand-tighten
until the final turn when a strap wrench can help tighten the
connection.
15. Reconnect the flex connectors and union connections.
16. Open the feed water inlet (slowly) to fill the tank.
17. Purge the air at a downstream faucet close to the system.
18. Once the tank is full, wait 4 hours for media to "hydrate".
19. Put the tank in service.
Alternative Method for
Replacing Media
Follow steps 1 – 6 then,
• Remove center distributor tube and lower basket and siphon
all water from tank
tank.
®
• Lay tank down on its side and tip upside down while using
hose to flush media out
• When all the old media is removed, stand tank back up and
install in original position. Fill the tank so that it is about half
full with water.
Then continue with steps 12 – 19.
