"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!"

"Excellent company excellent plumbers. Out water heater ruptured in the middle of the night and we had a plumber contacting us with next steps almost immediately at 2am. Greg, our plumber went above and beyond trying to get our hot water back as soon as possible and as cost effectively as possible and we can’t thank him enough for that. Great communication and a quick install. Can’t see us using anyone else for our plumbing needs."

"I thought it was really expensive because I got a 7 years contract.  They gave me a 50 gallon water heater because the specs were changing the following month for what’s required for water heaters so they gave me one that was bigger than I needed. It worked fine."

Water Softeners FAQs, answered by experts

Yes, you can have both a water softener and a water filter. In fact, some manufacturers sell dual water softening and filtration systems that treat hard water and provide clean drinking water. If you’re unsure about what you need or want to discuss your options, reach out to a local water softener installation company.

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.

Because it’s been through the water cycle, evaporating and becoming slightly acidic thanks to dissolved carbon dioxide in the atmosphere, rainwater tends to be naturally soft compared to groundwater, which has just been in contact with limestone. However, the natural hardness level of water always depends on where you are and other factors.

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 tankless water heater should be at least 10 feet away from a water softener, although the pros you hire for water softener installation can help you determine the correct distance. These two units need to have some distance between them to prevent hot water from the tankless water heater from flowing backward into the water softener when it runs a regeneration cycle.
