When brewing beer with tap or bottled water, chlorine and chloramine present in the water can combine with malt phenols in the wort to create a compound called chlorophenol, which can give the beer a medicinal taste. Cleaning your equipment with unfiltered tap water and not allowing it to dry properly will leave chlorine on the surface and lead to the same production of chlorophenol. Sediments and other total dissolved solids (TDS) present in tap water can give your beer a cloudy, hazy look.
For brewing purposes, undersink system are recommended over reverse osmosis (RO) systems because it keeps minerals vital to the brewing proccess in the water. The reverse osmosis membrane removes calcium, which produces an acid that helps balance the alkaline phosphates (pH) in the malt. It also removes magnesium, which helps the yeast produce the enzymes need for the fermentation proccess.
Next you'll need a carbon filter to purify the water. Carbon Block Cartridges are an inexpensive solution and serves two purposes in homebrewing. First is to remove chlorine and any foul tasting chemicals present in the water, which can give your beer a medicinal taste to it. It can also serve as a 'polish' to your beer, refiltering the finished brew will remove any fogginess (haze) and yeast.
