The picture above shows the basic set up for a gravity fed water filtration system. It is an extremely simple device that requires no electric power to use. Procure a couple of buckets (or other container types) locally and assemble them with the components below to create a fantastic water filter. Systems like this have been deployed in disaster relief situations around the globe for many years and have been proven to be very capable and reliable. (See the technical notes for details).

Siphon (BC-0108)
Our Price: $1.75

The siphon hose can improve the flow rate of any gravity or pressurized bucket system by 2 to 3 times.  Insert one end directly into filter spout and place the other end at the bottom of the container.  The hose will fill with water and form a natural siphon which will pull water through the filter.  

Made of food grade vinyl, comes in 2 foot lengths for use with standard 5 gallon stacked bucket configurations.
Pre-Filter Sock (BC-0105)
Our Price: $2.25

The pre-filter sock fits the 4x4 dome filter cartridges and is needed if you will be filtering water from a natural source such as a stream or pond that will have particulate matter in it.     This sock is installed over the main filter element and is used to remove larger particulates from the water.
Schrader Valve (BC-0120)
Our Price: $3.00

Air Pressure Valve for use in pressurized bucket systems.  Either style may be shipped.
Pre-Filter for 2 x 10 Candle Filter (BC-0305)
Our Price: $3.00

The pre-filter sock fits the 2x10 candle filter and is needed if you will be filtering water from natural sources such as streams or ponds that will have particulate matter in it.  The sock is installed over the main filter element and decreases how often the filter needs to be cleaned.
Replacement Spigot (BC-0104)
Our Price: $4.50

The replacement spigot comes with all of the mounting hardware.   (Color of Spigot may vary.)
Long Siphon (BC-0109)
Our Price: $5.25

This 6 foot long siphon can extend the flow rates of the 4x4 filters  well over 5x more than just dripping. (The higher the spout is from the other end of the hose the faster the water flow).    Insert one end directly into filter spout and place the other end in the collection container. The hose will fill with water and form a natural siphon which will pull water through the filter.   Makes a very nice alternative to pressurization,   they are also used for piping water in configurations where the collecting receptacle is not directly below the filter.  

See the 'separated' bucket system picture in the tech notes section for how the long siphon can be used with a bucket system.

Made of food grade vinyl.
5 Gallon Bucket with Lid (BC-0106)
Our Price: $8.50

Bucket and lid made from food grade plastic.   Use for gravity drip systems and bottom bucket of pressurized systems.

70 mil thickness,  Food Grade

Bucket bottom injection mold pattern is used as the hole pattern for spacing of multiple filters
Pressure Lid (BC-0107)
Our Price: $10.00

This Gamma Seal lid is used to create a pressurized bucket to increase water flow rate.  Increase depends on amount of pressure supplied.  This lid fits most 5 gallon buckets. (standard 11.5 inch diamater).  

The lids are advertised as air tight for normal storage purposes but we have found that they are not totally air tight when pressurized from within. Air will leak out slowly, however the water flow rates are still greatly improved.

This lid can also be used to create airtight, easy-open, storage for buckets instead of the regular hammer on/tear off lids that are commonly supplied.

Color of lid may vary.
