"Robert came from an Oakland job to check our sump pump which was not working. We needed a new one as water was building under our house and rains were coming. He replaced it and all the water went out. He was very professional, wore a mask. Would hire him again."

"I had water damage to the ceiling of my garage. Vicente provided evaluation and written estimate in one visit with attention to details and my customer satisfaction. He took the time to verify my plumbing problem by video taping my water leakage of my bathtub drain pipe with his phone through the broken spaces in the ceiling. He returned the next day with Eduardo, assistant, to complete repair with pipe replacement of old bathtub drain pipes. I was impressed with Vicente's respectful, honest, confident, and professional demeanor with attention to customer satisfaction and service. Vicente exceeded my expectations with exemplary work. Bonus: I discovered afterward that Vicente had fixed my slow flowing sink faucet next to bathtub without request or charge. I would request Vicente again for all my plumbing needs in future. Thank you Vicente. You are special!"

Water Softeners FAQs, answered by experts

It’s unlikely that hard water on its own could cause substantial hair loss or damage, though it’s true that bathing in hard water can cause your scalp to feel itchy or flaky and might dull your hair’s natural shine. Using high-quality shampoo and conditioner or buying a whole-home water softener can decrease these issues.

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.

Most experts agree there’s not much difference health-wise between hard water versus soft water. That said, hard water is more likely to cause skin dryness and issues that go along with it, like an itchy or flaky scalp. Hard water can also decrease the life span of your household appliances and make it more difficult for soap to do its job.

Softener systems extend appliance life spans, improve skin and hair health, and reduce pipe buildup by removing minerals like calcium and magnesium.

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.
