I just purchased a Berkey® system but the system is hardly filtering any water at all. Am I doing something wrong?
Typically the problem you are experiencing is due to high water tension, which prevents the air from being purged from the micro pores of the new purification elements. Water tension is higher in certain parts of the country and can change from season to season. The higher the water tension, the more difficult it is fot the water, using gravity pressure, to force the air from the micro-pores of a new element. Included with your Black Berkey™ elements is a priming button and instructions for use. Please remove and prime your purification elements, reinstall them and that should fix the problem.
I just purchased a Berkey® system but didn’t receive a priming button. Instead, I think I received an extra black washer in the box. The instructions say to use the tan colored priming button. What gives?
Please check in the box which held your Black Berkey™ purification elements. The box should contain two (2) elements. Attached to each element should be a rubber washer and a wing nut. Also in the boxes should be what could looks like another single black rubber washer. This is your priming button. It is thicker than the washer and the center hole is smaller. This black priming button can easily be confused with a washer; so we asked the manufacturer to change the color of the priming button back to tan.
The micro pores on the Black Berkey™ purification elements are extremely small, in fact they are small enough to filter red food coloring out of water. The benefit from having such extremely small pores is greater efficiency at removing pathogenic bacteria and other contaminates. The downside is that too much water tension can require that the purification elements be primed before they will flow properly. When you receive the purification elements, they are dry and air is trapped within the tiny micro fine pores. In certain parts of the world, water has more water tension than in other places and this can change from season to season. The higher the water tension, the more difficult it is for the water to force the air out of the micro fine pores using gravity alone. The pores that have air trapped within them do not allow water to pass through and therefore become an inaccessible passage for the water. This then can cause the system to either filter very slowly or not at all.Before traveling to the field or using the system in an area without water pressure, we recommend that the purification elements be primed using the priming button method. If water pressure is not available to use the priming button method, the elements can be field primed approximately 50-75% by using the below method. In other words by using this method, the elements will not purify as fast as they will by using the priming button method however they will run significantly faster than if the elements have not been primed at all. The field priming method is as follows:
STEP 1: Fill the lower chamber with water, then place the purification elements into the water in the lower chamber, upside down with the stems facing upward. Put a ceramic coffee cup (or something else that will hold them under the water) on top of each purification element stem to force the element down under the water.
Or, install the elements upside down in the upper chamber so that the elements are on the exterior of the bottom side of the upper chamber facing downward. Then place the upper chamber onto the lower chamber so that the filters are forced into the water within the lower chamber.
Let the purification elements soak in the water for 30 to 60 minutes until they fill up with water. NOTE: Make sure that the opening in the stems of the purification elements are not underwater as the water must be forced through the pores of the element and not allowed to enter the element through the hole in the stem.
STEP 2: When the inside of the purification elements are full of water they will be significantly heavier. Next, assemble the purification elements into the upper chamber while keeping the stems of the elements facing upward. It is important to keep as much water on the inside of the purification elements as is possible. Next, fill the upper chamber with water as quickly as possible. Hint: the fastest way to fill the upper chamber is to pour the water from the lower chamber into the upper chamber. Then place the upper chamber onto the lower chamber.
When the purification elements have water within the bore (inside core), more force is generated to draw water through the purification elements. This is because the water that drips out of the purification element also hydraulically pulls new water into the element as it begins to work like a siphon. Thus, in addition to the “Push” of gravity, there is also a hydraulic “pull” and this drastically improves the ability of the water to force the air from the micro pores. The above method is less efficient than priming the purification elements with the priming button but should be about 50-75% effective in clearing the blocked micro pores.
Let the water from the first purification cycle that is collected in the lower chamber run to waste. Next, refill the upper chamber with water. Your Black Berkey™ elements are now FIELD primed and your Berkey® system is ready for use.
Note: If the water used to field prime the elements is from a contaminated or suspect source, if possible use a container other than the lower chamber to immerse the elements. If this is not possible then use the water that collects in the lower chamber from the first purification cycle to make a soapy dishwater. Then wash thoroughly the inside of the lower chamber and discard the soapy water. Next, purify more water and use it to rinse any remaining soap from the lower chamber. Your Berkey® system is now ready for use.
