"Job well done. I had to have old water lines replaced as well as a new hot water heater in the basement. My water pressure and temperature is now much better thanks to replacing old steel pipe with pex. Very fair price and was done in about 6-8 hours."

"Pure Water beat the other contractors on price and what we received as a product. We couldn't be happier with the installation. We now have hot water on demand on the opposite side of the house where it could take 5 min of water running for the water to be hot. Pure Water also installed a water softener and now our hard water is soft! Patrick who did the install was professional, personable, picked up what little mess there was, explained everything once the install was complete. We are so pleased we have them on the hook for a fireplace gas line and will have several bathroom projects going forward. We could not recommend Pure Water Services more. Thank you"

"Honest and good work can be hard to come by. Jay will get the job done right for a very reasonable cost, and he is incredibly kind on top of all that. So far Compass plumbing has: split pipes in my en suite bathroom from a single to a double sink, moved water lines from the floor to the wall to accommodate a floating vanity, moved a toilet location in my basement, replaced a water pressure regulator that was causing water hammer, and fixed a leak coming from the line going to our fridge. Definitely my go-to plumber!"

"I would highly recommend this company! My service pro was knowledgeable, friendly, and efficient! He took on an old, leaking, rusted water heater job that was not for the faint hearted. He problem solved every odd glitch that my older house threw at him. The whole experience was completely positive!"

"Excellent...we had some additional issues related to water pressure regulator, piping, etc. The situation happened on the weekend and we had hot water running by Monday afternoon. An EXTREMELY short time compared to our last water heater issue. Highly recommend Heart and will use them from now on."

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.

If your ‘do isn’t doing what you want it to do despite using good hair care products, hard water might be to blame. Since hard water can’t rinse soap off as well as soft water can, your hair might grow limp because of the shampoo and conditioner residue that’s left behind. If you color your hair, you might see it fade more quickly or even turn a different shade as the dye reacts with the minerals in the water. You might also experience an itchy scalp, thanks to the dryness that comes from bathing in the hard water.

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.

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.
