"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."

"Justin was professional and knew exactly what I needed to fix my existing water heater without trying to upsell me on a much more expensive tankless water heater. He had the relief valve and expansion tank in his truck and was able to install everything without issue. I would recommend hiring them for your plumbing needs!"

Water Softeners questions, answered by experts

Some shower water softeners are effective, but this isn’t always the case. Most shower filters only filter out chlorine, not hard minerals like calcium. Other shower filters can't handle the demand in homes with very hard water. It's also important to change the filters on your shower filters. Failure to regularly swap out old filters will make the filter ineffective over time. 

Softened water prevents scale deposits, reducing appliance wear, leading to energy savings and longer-lasting household fixtures.

Installing a water softener could help reduce calcium buildup in your pool if your pool has high calcium hardness as a result of hard drinking water in your home. Pool softeners work by exchanging calcium and magnesium for sodium, so if you use softened water to top off your pool, it may help keep calcium hardness from rising over time. However, it won’t lower the calcium hardness of the water already in your pool and isn’t a practical way to control pool calcium levels. The average water softener installation cost is between $200 and $6,000.

The chemicals in a water softener can wear down the anode rod in the heater and shorten its life span. However, for most people, the benefits of the softener outweigh this potential drawback.

Have a plumber inspect the anode rod annually for damage, as replacing the anode rod is far less expensive than replacing the entire water heater.

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.
