Plumbing in your CBF1 Filter

  

 

Turn the power off to the well pump then shut off the main water shut off 
valve which should be located after the pressure tank. If your hot water tank 
is electric, turn off the power to it to avoid damage to the element in the 
tank. Open a faucet closest to the pressure tank, but after the main shut-off 
valve to de-pressurize the lines. 

 

The bypass valve generally comes pre-assembled. If not, attach the bypass 
valve to the control valve by pushing it in and secure it with the metal clips 
and screws (

Fig 3

 

Insert Allen key into the bypass handles and make sure that the valve is in BYPASS position (fig 5A) 

 

Fully push the inlet/outlet elbow fittings into the open end of the bypass 
valve and lock them in by inserting the red locking clips into the slots (

Fig 4

 

For ease of installation, orient the inlet/outlet fittings in the direction of the 
inlet & outlet pipes by simply rotating them (

Fig 5B)

 

 

Plumb in the inlet and outlet of the CBF1 filter.  

 

Plumb in a ½” flexible plastic drain line running from the filter (elbow hose 
fitting) (

Fig 6).

You can run the drain hose from the unit to the ceiling joists (max 
8 ft ceiling) and run it to the nearest laundry tub or drain pipe. 
This can be ran up overhead or down along the floor. If running 
drain line more than 30 feet overhead, increasing the line size to 
3/4" will be required. Please follow your local health dept. Codes 
for where to run filter discharge water. NEVER MAKE A DIRECT 
CONNECTION INTO A WASTE WATER DRAIN. A PHYSICAL AIR GAP 
OF AT LEAST 3" SHOULD BE USED TO AVOID BACTERIA AND 
WASTEWATER TRAVELLING BACK THROUGH THE DRAIN LINE 
INTO THE CBF1 FILTER (

Fig 7)

.  

o

 

There will be a fair amount of pressure on this flexible plastic 
drain line when the filter is in the backwash mode, so secure it 
to the drain fitting by a hose clamp. Also secure the drain tube 
to the wall or ceiling.  

 
You can also use code-approved air-gap attachments available at most plumbing stores. 

 
 
 
 
 
 
 
 
 
 

 

 

 

Turn on the switch for the well pump. If you had emptied the pressure tank, allow it to fill up until the well pump shuts 
off. Slightly open the main shut-off valve. 

 

Insert the Allen key into the inlet side of the bypass valve (

Fig 8

) and turn it on only slightly 

and watch for leaks. Now insert Allen key to outlet side of the bypass valve and turn it on 
slightly. Make sure a faucet is on somewhere and that any aerator is removed to avoid 
clogging from loosened scale in the pipes. Leave the bypass valve in the same position and 
slowly turn the main shutoff valve on all the way. If you have no leaks, proceed to the next
