"Perfect! I called Western Rooter the AM my disposal went out. They were at the house the same day, at the time they stated they would arrive. The work was done efficiently and professionally and completed within an hour. I have called on Western Rooter for many years for various plumbing needs (clogged drains, replace water-heater, replace main water line, etc.) and have always had great, timely service at reasonable $$$."

Backing up? Got roots? Blast those roots out with a Hydro Jetter! We use a wart hog nozzle that combines controlled rotation with a unique 8 jet cutting configuration optimized for removing roots. It’s better with a jetter! Call us! We got this! ??

"I really appreciated how quickly Robert responded to my calls for service. Initially, I wanted a non-functioning water softener system removed. Robert scheduled the work to be performed within a couple of days of my request. My family was very pleased that his team could haul away the old water softener tank, and that they left the vacant area in such great condition. A few days later, I needed immediate help with a "running", leaky toilet. His team was on site within an hour of my request and quickly resolved the problems. In both cases, Roberts efforts to address our needs in the time frame we needed, the quality of work, and friendliness of everyone involved was outstanding."

"Great crew and awesome service. I had a hard time finding a place interested in dismantling a rusty failed 10k steel water holding tank. These guys got it done quickly, cleanly and they were very nice and good about communication. Top notch!"

Dutton Plumbing, Cooling, Heating & Electrical runs out of two locations, one in Simi Valley and one in Sylmar. We’ve been working out of this valley since 1987. From those two shops, we cover Ventura County, the San Fernando Valley, Santa Clarita, and Northern Los Angeles County. That’s plumbing, drain and sewer, water heaters, HVAC, and electrical, all handled by the same crews. Nearly four decades in the same region adds up. Our crews have been inside enough houses out here to recognize what a given neighborhood tends to do before they open anything up. Post-war ranch homes behave one way, newer builds behave differently, and we’ve seen it all.

Water Softeners FAQs, answered by experts

Whether you need a permit or license for a water softener installation depends on your location, as requirements vary significantly. Some municipalities require the installer to hold a plumbing license, some mandate a permit and an inspection, and others require both. In some areas, no special permit or license is needed at all.

To determine the rules in your area, you can contact your local building department or consult a local water softener installer or plumber. Often, only certified professionals are authorized to pull the necessary permits, and they will typically handle the entire permitting process for you. Regardless of local laws, it is always recommended to hire a licensed professional to ensure the system is sized and installed correctly. You can use Angi’s state licensing tool to check an installer’s license status.

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.

A water softener removes minerals from your drinking water and can make your house water softer. These softeners are designed to extend the lifetime of your plumbing system while also making water safer and more palatable for drinking. Hard water, which is water with a heavy amount of suspended particles, can also cause hair damage, skin irritation, and buildup in your pipes.

Water softeners have many benefits. The most important one is converting previously hard water—water with too many minerals—to more usable, easier water. When we say easier water, we mean water that’s easier to digest, less harsh on skin and clothes, and builds up less in the water system. Softer water may lead to lower energy costs and will extend the lifespan of all appliances that use water.

Hard water isn’t necessarily bad for you. In some ways, it’s good for you. If you’re deficient in magnesium or calcium, hard water can give you a mineral boost that you wouldn’t get with soft water. However, this is where the benefits of hard water pretty much stop. Hard water can cause many minor inconveniences and lead to costly, premature replacements of your water-using appliances.
