"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!"

"The pressure pump on our well system failed on July 4th. We have a irrigation system for our extensive home vegetable garden and dreaded the prospect of hand watering half an acre of crops. Romero (The owner of Quality Pump Service) returned our phone call over the holiday weekend within a hour. They are a family run business. He was willing to come to our home and install a temporary pump on Sunday as a new pump would not be available for two days (Remember it is the July 4th Holiday weekend). In short, we were completely repaired in two days with a new pump and new pressure tank. We checked on-line retailers to see if Romero had overcharged us for the new components. He was within 5% of the average retail price which would have been our cost if we had fixed the system ourselves. His team was fast, pleasant and professional and given the holiday emergency response very fairly priced. We feel we can highly recommend Quality Pump Services."

"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 FAQs, answered by experts

No, hard water isn’t dangerous. The added calcium in hard water can contribute to good bone health. However, it can also cause dry skin and hair. If you have dry skin or hair, consider using a water-softening system to help minimize the minerals in your water. Plus, these systems can also add some sodium to your diet. 

While it depends on how complicated the unit and installation is, it takes two to four hours to install a water softener unit, on average. It might take longer if pipes need to be replaced. You should make sure the installation area is clear of any objects that might get in the way before you begin.

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.

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.

Drinking hard water is not known to have any negative health impacts. Using hard water can lead to dry skin and hair, and the minerals in hard water can build up in pipes, faucets, and appliances. Hard water is more of a threat to your plumbing than it is to your health.
