"The Tankless Guys not only installed a new water softener system, they also put in a new tankless water heater and a new toilet. They provided excellent service. We had a range of options to choose from and Sergio and his team performed all the work in a timely manner. Sergio also answered any questions we had thoroughly. I highly recommend them!"

"We recently had Mega Power Electric Inc install a solar system and panels. The President and provided excellent communication all the way through the process. He even met with us after installation to explain the almost incomprehensible PG&E bill. Although not the least expensive bid, his was competitive and I felt he was as interested in educating me about solar and the various types of panels and inverter systems as he was in selling a system. He demonstrated how the array of panels would meet our energy needs and as opposed to some of the other companies, wasn't selling us more than we needed. We are very satisfied with our solar system and I highly recommended Mega Power Electric Inc."

"It was great luck that Jason of J Drains was working on a job near my home and was able to come by after he finished that job to check my hot water heater. He fixed it right away because he spotted what was wrong quickly. Jason was very professional and polite. I recommend this company!"

Water Softeners questions, answered by experts

Installing a water softener could help reduce calcium buildup in your pool if your pool has high calcium hardness as a result of hard drinking water in your home. Pool softeners work by exchanging calcium and magnesium for sodium, so if you use softened water to top off your pool, it may help keep calcium hardness from rising over time. However, it won’t lower the calcium hardness of the water already in your pool and isn’t a practical way to control pool calcium levels. The average water softener installation cost is between $200 and $6,000.

The most effective way to fix hard water in your shower is by installing a whole-home water softening system. This system treats water as it enters your home, removing the minerals that cause hardness before they can reach your shower or any other fixtures. While this is the most comprehensive solution, other methods are often temporary fixes. For a more affordable and shower-specific option, you can install a water-softening showerhead or a shower filter. However, these filters are generally less effective and may not remove all the contaminants that lead to limescale and hard water stains. By implementing a water softening solution, you can expect a reduction in mineral deposits and enjoy the benefits of cleaner-feeling hair and skin.

It’s not a good idea to oversize your water softener. Doing so will mean the tank doesn’t get full, which can lead to channeling. This leads to a large portion of the resin beads not being utilized and the beads at the bottom of the tank being overused. Over time, this will reduce the efficiency of your system, not to mention that the upfront cost of an oversized softener is unnecessarily high. If you have a timed regeneration cycle rather than a demand-based one, you’ll also spend far more on replacing salt than you need to.

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.

It depends on the type of surface. For instance, if you’re trying to get rid of hard water deposits on glass, you can spray vinegar onto the surface and wipe it off with a soft cloth or non-abrasive sponge. However, if the deposits are on granite or natural stone, it’s better to use baking soda and water rather than vinegar or other acidic cleaners.
