"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

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.

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.

You can use a commercial water repellent treatment for glass on your shower doors to prevent water spots. Take care to only apply the product to glass. Letting air circulate also helps prevent water spots, as water is less likely to remain on the glass for a long time with good air circulation. Run your vent fan, open a window, and leave the shower door open for about half an hour after using the shower.

A single shower consumes an average of over 17 gallons, while brushing your teeth with the water running uses up to four unnecessary gallons. Watering the lawn spreads hundreds of gallons of water across the yard each time. Limiting water usage in these areas can significantly cut down your water bill.

There are many possibilities for why your shower’s water pressure is low. It might be a simple-to-fix issue like the water valves being partially turned off, a dirty showerhead or hose, leaks in the plumbing, or an old showerhead. However, low water pressure in the shower could also indicate a larger issue with your home’s plumbing system.
