pieces of copper pipe, or some other non-corrosive material but do not use wood. The filter can sit directly on the floor, 
it will not corrode. DO NOT set the tanks onto make shift platforms as this may cause the filter to topple.  

 

The following materials can be used for installing your new system, but it is recommended that you check your local 
plumbing codes. Copper and PVC, CPVC, and PEX are the most popular.  

 

You may choose not to treat the water spigots that go outside used for irrigation or sprinkler systems. You will have to 
plan the job so that you cut in to feed the CAFE filter AFTER these spigots. Installing the CAFE filter after the pressure 
tank (with air injector between pump & pressure tank) is the preferred location. If you intend to install a water softener 
to soften the water or a UV system to disinfect the water, these should be installed 

after 

the CAFE filter.

Plumbing in your CAFE Iron 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. Open a few 
faucets and empty the pressure tank before cutting into the line. If your 
hot water tank is electric, turn off the power to it to avoid damage to 
the element in the tank. 

 

 

Position the filter in the desired location, which is after the pressure 
tank 

(

Fig 1)

 

 

 

Attach the bypass valve to the control valve by pushing it in and secure 
it with the metal clips and screws (

Fig 2

). 

 

 

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 3

 

 

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

Fig 4)

 

 

 

Plumb in the inlet and outlet of the CAFE filter. We recommend using 
Rainfresh CKS solder-less connector kit for easy installation. This can be 
ordered from the same retailer where you purchased the unit from, or 
call Rainfresh. 

 

 

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

(Fig 5)

. 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 1.5” SHOULD BE USED 
TO AVOID BACTERIA AND WASTEWATER TRAVELLING BACK THROUGH THE DRAIN LINE 
INTO THE IRON-FILTER (

Fig 5A

). 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.  

 

 

Plumb in the air-injector (1” Female NPT connections) (

Fig 6

) at this spot. 

DO NOT ALTER THE SETTINGS OF THE AIR 

INJECTOR. 

It can be installed in a vertical or horizontal position.  

 

o

 

Allow a minimum of 6 inches straight run of pipe on each side of the air-injector (

fig 6)

, excluding fittings.  

o

 

Make sure that the arrow on the air-injector points to the pressure tank and pressure switch. 

Note: 

Locating pressure switch before the air-injector can cause rapid ON/OFF cycling of the pump.  

o

 

The check valve should also be located before the air-injector (may require re-location of the check valve to 
accommodate air-injector at the correct location). 

o

 

It is recommended that a strainer be installed before the air-injector to prevent dirt/grit from clogging the 
air-injector.
