"Brad came by to inspect our very old water softener that had stopped working. He determined it needed to be replaced and had a new one installed for us the following Monday. He was very informative and didnâ t charge us an arm and a leg. I highly recommend Maineâ s Best Water Treatment."

"I am very pleased with the knowledge, professionalism and payment arrangements to install this system into my home. I was concerned with consumption and showering with my tap water. I no longer have to worry. For myself, family and friends, I know I’ve made the right choice with the right company."

"Rick was very friendly and informative. We had him come in for a water system quote to remove iron and manganese from our water. He sampled our water, gave us the results immediately and also tested our air quality. He was so thorough and knowledgeable that we were able to close the deal on both a water treatment system and air purifiers that are already making a noticeable difference!"

"The company's responsiveness to our urgent situation was extraordinary. The owner made a 60 mile trip to examine our situation on Sunday morning! He expected at least a week before they could do the work, but he got it done the next morning so that we would have safe water...we had been waiting for another contractor for more than 3 months! The installed radon mitigation system has performed flawlessly. We are grateful and confidently give AquaMax our highest recommendation."

Water Softeners FAQs, answered by experts

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.

If your water softener repair is fairly straightforward, like a simple filter replacement, then you can probably do it yourself with little risk. However, anything beyond a simple fix should be addressed by someone with extensive plumbing expertise to avoid costly water softener problems, like leaks. 

That said, even simple problems can be complicated to diagnose, particularly if your water softener is attached to a whole-house treatment system. So, unless you feel absolutely certain that the problem is an easy fix that you can take on yourself, it's probably best to hire a plumber to diagnose and fix the problem.

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.

You should not use a water conditioner with a water softener because a water conditioner changes the chemistry of the water and causes the ion exchange in a softener to be ineffective. Choose a water softener if you have hard water or well water, and use a water conditioner if you need to remove certain contaminants.

Yes. To get soft water, you can install a water softening system, which will replace the calcium and magnesium ions in the water with sodium or potassium ions. Water softeners cost anywhere from $200 to $6,000, depending on the size and complexity of the system. You can either install a water softener for the whole house or just at your shower heads. If you’re sensitive to sodium or potassium, you can install a salt-free water conditioner.
