"The whole project went very well. They helped tremendously from start to finish with several ideas & advice. They ran into some unseen problems with the floor repair but were able to work it out & come up with a good solution. We are very pleased with the final results & would highly recommend their work. They were always on time & arrived when they said they would."

Water Softeners questions, answered by experts

While not everyone can detect taste differences in high-calcium water, water that has a slightly metallic taste probably has too much calcium.

Choosing involves understanding water hardness levels, household size, desired features, and consulting professionals experienced in suitable system types.

Experts recommend that you put two to four bags of potassium chloride in your water softener every month. This amount depends on how much is in the bag (40 pounds is most common) and what your water softener manufacturer recommends. For more specific advice, talk to a water softener pro in your area and read the manual that came with your system.

A good hardness level for drinking water can vary based on personal preferences, but an ideal level is 3.5 to 7 GPG. This means your water isn’t soft or hard. However, some people prefer the “fresh” taste from the minerals in hard water, while others like the smoother, “slippery” texture of soft water.

You should not use a water conditioner with a water softener because a water conditioner changes the chemistry of the water and causes the ion exchange in a softener to be ineffective. Choose a water softener if you have hard water or well water, and use a water conditioner if you need to remove certain contaminants.
