Building a Water Filter for Brewing
Building a water filter for brewing is fun, useful and can be done in 4 easy steps. Everything can be purchased at your local hardware store for a little under $40.
1. Purchase the Equipment
2. Connect the Fittings for the Water Hose
3. Connect the Barb and Exit Hose
4. Usage and Cleaning
Brewing requires the use of filtered water. When I say filtered, I mean water that has been removed of bad odors along with most of its chlorine and chloramine. Water is very important to the beer, think about it, beer is mostly water. Many styles of beer, taste the way they do because of the water used to brew them.
Pilsen, Czech Republic — Soft Water, mostly free of any bicarbonates
Burton, England — Hard Water, very high levels of bicarbonates
Rocky Mountains, USA — Spring Water
For the most part in America, your tap water will probably do just fine, after it has been ran through a charcoal filter of course.
Purchase Equipment (30 minutes)
1. Whirlpool Whole House Filtration Package (WHKF-DWH)
2. Whole House Carbon Wrapped Filters (fit inside filtration system)
3. 1/2″ barb to 1/2″ MPT Adapter (brass)
4. 3/4″ x 3/4″ x 1/2″ Adapter (brass)
5. Poly Shut-Off Valve (outdoor water hose section)
6. 4 ft of Plastic Hose (1/2 inch) (Food Grade Quality)
Connect the Fittings for the Water Hose (5 minutes)
Connect the brass 3/4″ to 1/2″ adapter to the water filter using Teflon tape. Then screw into it the poly shut-off valve(simply an adapter for water hoses and adds a shut feature). The poly shut-off valve will allow you to control the flow of the water before it reaches the filter.
Connect the Barb and Exit Hose (5 minutes)
Connect the brass barb to the water filter using Teflon tape. Then with a hose clamp attach the plastic hose and tighten it down. This hose will be the exit hose for the filtered water.
Usage and Cleaning
Note that this water filter system is best used outside. To use the water filter attach the water hose to the shut off valve. Slowly turn on the water while pressing down on the RED tab at the top of the filter. Once the water begins to flow, take your finger off the tab and began using the water. Cleaning is easy, simply unscrew the top to the filter tube and remove the filter, let the filter sit and dry before putting back inside filter tube for storage. Removing the filter after each brew session should help against mold buildup inside the tube. Its also helpful to have a mount for the filter, check out the mount that was built onto Black Betty the brew tower.
