Both brands have test results for hundreds of contaminants, but good test results should also indicate that protection is sustained for a reasonable number of gallons of use.

British Berkefeld has specialized in and perfected the use of ceramic filters for water purification for almost 200 years. Purification refers to the removal of micro-organisms.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMy gravity system is full of water, but no water comes out when I open the spigot.\u003c\/strong\u003e\u003cbr\u003eIf you open the spigot and lift the upper chamber off the lower chamber, does water flow out of the spigot? If so, it means your upper chamber sits so tightly into your lower chamber that an airlock has been created. An easy solution is to create a slight air gap between the upper and lower chambers by bending a paperclip or a twist tie over the upper lip of the lower chamber.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy has water leaked around the base of my gravity filter system?\u003c\/strong\u003e\u003cbr\u003eCheck that your spigot washers are properly positioned, and that the spigot is sufficiently tightened to prevent leaks.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow often should I clean my British Berkefeld system?\u003c\/strong\u003e\u003cbr\u003eWe recommend cleaning your housing once per month with warm soapy water. Use dilute vinegar on the stainless steel housing to remove any limescale build up. Do NOT use warm water, vinegar, or soap to clean the ceramic replacement filters.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe upper and lower chambers of my gravity system never empty completely. Is this normal?\u003c\/strong\u003e\u003cbr\u003eYes, this is normal. This remaining water in the upper chamber will be pushed through the filters when the next batch of water is introduced. The water below the spigot hole in the lower chamber will be mixed with the next load of water that filters through from the upper chamber. In this way, all the water in your system keeps moving along and gets continually replaced by new, incoming water.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use red food colouring to test ceramic gravity filters?\u003c\/strong\u003e\u003cbr\u003eThe red dye test (recommended by Berkey) suggests that red food colouring is an appropriate surrogate for demonstrating whether waterborne contaminants can pass through your gravity filter. This is misleading.\u003cbr\u003ea. Red food colouring is not an appropriate surrogate for waterborne contaminants.\u003cbr\u003eb. Passing red food colouring through a gravity filter is not an indication of contaminant removal or filter performance.\u003cbr\u003ec. Red food colouring, itself, is not safe to ingest so why needlessly stain your white ceramic filters with it. \u003cstrong\u003e\u003csmall\u003eDO NOT perform the red food dye test on ceramic water filters.\u003c\/small\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow can I test to make sure my filter is working?\u003c\/strong\u003e\u003cbr\u003eAccurate testing can only be done by a lab equipped for testing water samples. This is expensive.\u003cbr\u003eThe best approach is to purchase a water treatment device that has already been tested by accredited labs for the sustained reduction of contaminants known to occur in your local tap water. Once properly assembled or installed, maintain the device with regular cleaning and cartridge replacement.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow often should I clean my ceramic filters?\u003c\/strong\u003e\u003cbr\u003eCleaning frequency will be determined by your local water conditions. As the white ceramic becomes increasingly discoloured, the flow rate through the filter will probably diminish. When the flow rate becomes annoyingly slow, remove the cartridges from the housing. Hold each one under cool running water and scrub the discoloration off the surface of the white ceramic. Reinstall the cartridges and resume use.\u003cbr\u003e\u003cbr\u003eNOTE Be careful not to let any scrubbing water enter the threaded end of the cartridge during the cleaning process.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long can I store unused ceramic filters?\u003c\/strong\u003e\u003cbr\u003eAs long as they have never been wetted, you can store unused ceramic Berkefeld filters indefinitely in a clean, dry location away from fumes. Leave them in their original packaging and wrap the entirety tightly in a clean plastic bag.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat should I do with my filters and system when I am away on vacation?\u003c\/strong\u003e\u003cbr\u003eIf the system will be unused for more than 3 days, remove the ceramic filters from the housing, drain as much water as possible out of the threaded end of the filters, lay the ceramic filters on a drying rack or in such a way as to provide clean air circulation to all sides of the cartridges while you are away. Empty the housing. Leave the upper and lower chambers inverted on a drying rack. When you return from vacation, re-install the ceramic filters and flush one entire batch of water through the system before resuming use.\u003c\/p\u003e\n\u003cp\u003eDo not leave wet filters unused in a location where they might freeze…such as overwintering them in a summer cottage.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli id=\"tab3\"\u003e\n\u003cdiv class=\"resp-container\"\u003e\u003ciframe src=\"https:\/\/drive.google.com\/file\/d\/1vG4SXpvJkfRT2Tbz1hxghm6yT-yvqyZi\/preview\" class=\"resp-iframe\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Watermatters","offers":[{"title":"Default Title","offer_id":46174165532823,"sku":"W9361141","price":656.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1570\/1593\/files\/BritishBerkefeldStainlessSteelGravitySystem-large12L.jpg?v=1711069173"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1570\/1593\/collections\/British_Berkefeld_Gravity_Water_Filters.webp?v=1704836361","url":"https:\/\/www.watermatters.ca\/collections\/british-berkefeld.oembed","provider":"Watermatters","version":"1.0","type":"link"}
