Water Loop Overview
A water softener loop is used to provide easy access to the plumbing system of a house. A section of pipe exits the wall and is exposed. This allows plumbers to access the water line. The pipe fixture "loops" back into the wall, where it stays hidden and plumbs the rest of the house.
Soft water loops are used to provide easy access when a water softener needs to be added or replaced. Often, this feature can raise the value of a house, as future buyers can modify the water softening system without expensive renovations.
Accessing the Loop
Soft water loops are usually accessed in a garage or closet location, where they are out of the way. When a water softener or filter needs to be added, a plumber cuts into the exposed loop. Fittings are used to connect the new appliance into the pipe system.
As water enters the house's plumbing system, the water loop immediately directs it into the installed water softener. This way, all incoming water is treated before it circulates.
Water Loop Maintenance
The area holding a soft water loop should feature a utility drain and an electrical outlet. The drain protects the floor in case of a leak, while the AC outlet powers an installed water softener. If these features are not found at the water loop site, they should be added before a softener is installed.
Soft water loops do not require significant maintenance. However, they should be checked for leaks on a regular bases and repaired as needed. Water loops exposed to cold areas, such as those installed in garages, should be insulated adequately to prevent freezing.
