What Does A Water Softener Do?
Water softener is a tank system that removes the ions (i.e., usually calcium and magnesium) from the water supply to make it softer.
-Over 80% of hotels in the US require water softeners.
- In the most cases, a water softener is mandatory when water hardness is more than 5 grains per gallon in hot water and 7 grains per gallon in cold water. A water test can determine the water profile for requirement of a water softener.
-Hard water – when left untreated – can clog plumbing systems with limescale and significantly reduce the lifespan of the plumbing equipment and fixtures.
-After treatment, the water softens and easily liquefies soap for easier removal of soap scum from sinks and tubs.
What Types Are There?
There are several different options of softeners; however, the best option is a softener that uses ion exchange. Ion exchange is the technology most commonly used in water softeners.
What Size Do I Need?
-A typical 120-key hotel needs two 24” diameter softener tanks and one 30” diameter brine tank. These tanks take up an approximate 7’ by 2.5’ footprint in the water heater room.
-Choosing the size of the system required for each hotel is critical for effectiveness.
-Oversized systems can lead to hardness leakage due to inefficient flow rates.
-Undersized systems lead to pressure issues.
-Your MEP engineer should work directly with softener representative to ensure it is properly sized.
How Much Do They Cost?
A water softener for a typical 120-key hotel can range from $5,000-$10,000.Cost fluctuations depend on whether you plan to soften only hot water or both the cold and hot. Since hot and cold water are mixed, most manufacturers recommend treating both sources.
