A line by-pass filter may be installed in one of two locations. The first location is beneath the sink where it is attached to a line leading to a separate faucet at the kitchen sink. The second location is in the water line after it enters the house. The latter requires installation of a valve in the water line ahead of the filter in order for the water that is drawn from the regular faucet to be shut off. A stationary water filter is installed in the cold water line under the sink.
All cold water flowing through the pipe to the kitchen is filtered.
The tightly wrapped fibers form a cylinder around a tubular opening. Line pressure forces water through the wrappings to the inner opening that leads to the faucet. The fibers trap silt. Filtered water passes to the opening that leads to the faucet. Water filtering devices using activated carbon.
