USA made Red Food Colouring liquid to test your Berkey Systems.  

 

1  x  10ML bottle of artificially made USA Red Food Colouring 

 

To perform a food colouring test, start with an empty system (upper and lower chamber) remove the PF-2 Fluoride filters (If you have them)  and place a glass in the lower chamber directly underneath each black berkey filter.

 

Next, fill the upper chamber with water and add up to 1/2 teaspoon of red food colouring.    -   Please note,  It's enough to add 3-5 drops.  

 

(see photos below of the red colour water.  

Do not add all the bottle.   

 

Only 3-5 drops max.  

After 5-10 minutes, look to see if any of the water in the glasses are red or pink.  

Water should come out clear and if there is a red or pink colour in the water then please check if the filters are installed correctly or washers positioned correctly or if the wing nuts are loose and then make a new test. Also make sure the filters are primed correctly - Please see our priming and cleaning videos under our FAQ page and YouTube. - Filters needs to be cleaned and primed every 12 months
