Operating Pure Water Products' Style A Siphon Filter

1. Find a container for the water you are going to filter. A rectangular, flat-bottomed container is best, but other types will work. Fill the container with clean (potable) water and drop the ceramic candle into the water. The position doesn't matter as long as the water will cover the candle. LET IT SOAK UNTIL IT WON'T FLOAT BEFORE ATTEMPTING TO USE IT AS A SIPHON FILTER. This may take an hour or so and it may take overnight. You can speed the process up by putting an object on top of it to hold it under water. (After the initial use of the ceramic candle, such extensive soaking will not be necessary.) IMPORTANT: IF CLEAN WATER IS NOT AVAILABLE FOR SOAKING THE CANDLE, , INSTALL THE SIPHON ADAPTER ON THE CANDLE AS INSTRUCTED BELOW BEFORE SOAKING. BE SURE TO KEEP THE OPEN END OF THE TUBE WELL OUT OF THE WATER TO AVOID CONTAMINATION.

2. . Assemble the filter by screwing the female fitting attached to the hose onto the male fitting of the ceramic candle. Be sure that the O ring is inserted onto the stem of the candle. For added security and to assure the tightest seal possible, the threads of the candle should be taped with two or three wraps of teflon pipe thread tape. Teflon tape is sold at all hardware stores Tighten the fitting onto the candle until the O ring is firmly against the shoulders of the fitting.

3. Select a container to receive the filtered water. Any clean container will work. (Actually, a dirty container will work, but you'll have to drink dirty water.)

4. Arrange the two containers so that the dirty water container is above the clean water container. The greater the difference in elevation, the faster the filter will work.

5. Start the filter by sucking water through the hose as if it were a soda straw until you get water in your mouth, then quickly lower the hose to allow water to flow into the clean water container. The water should continue to flow. If it doesn't, repeat the process until you get a start. Several attempts may be necessary. (If you suck until your eyeballs pop out and can't get water to come through the candle, it means you ignored the presoaking instructions in step #1.)

6. Once the filter has started, it will continue to filter water into the clean water container until the upper container runs out of water. Simply adding water to the upper container will restart the filter even if the container has run dry.

7. Discard the first batch of water you filter. Any water filter, this one included, always needs to run awhile to rinse itself out when it's new.

Assembled System

Maintenance

1. The filter needs no maintenance as long as flow is good. When flow gets slower, clean the candle by holding it under running water and wiping it clean with a cloth or a mildly abrasive pad.

2. The filter will last indefinitely. It should be replaced when a significant amount of the ceramic outer surface has been worn away by cleaning, or until it becomes so filled with contaminants that cleaning will not restore normal water flow.

3. Filters with a carbon inner core (Super Sterasyl) have a shorter lifespan and should be replaced when the carbon is expended. Failure to improve the taste of the filtered water is an indication that replacement is needed. If chlorinated water is filtered, replace when the filter fails to remove chlorine.

4. The hose can be trimmed to a convenient length, but keep in mind that the greater the elevation, the faster the production.

Capability of Filter

Doulton ceramic cartridges are capable of making virtually any water safe to drink from a microbiological standpoint. They are not designed to remove heavy chemical contamination. You can filter pond water and drink it, but be selective. The clearer the water, the less cleaning you'll have to do, and the longer the element will last.

If you use a carbon filter like the CeramiKX, for best results chlorinate the water lightly to be sure bacteria are killed. The carbon filter will remove chlorine and finish the job. Carbon filters usually require more pre-soaking than ceramics before use. Be patient. Weight the cartridge down to hold it under water and don't waste your breath until it won't float.
