"I purchased an electric tankless and pre-filter/softener directly from the manufacturer and started hunting for a plumber to install it. Now most all plumbers recommended against a tankless hot water heater, and Maplewood wasn't really any different in this regard. BUT, they listened to us, didn't treat us like idiots, and obliged us in our foolishness and they were really awesome. They did the job quickly and without a mess. Also, WE LOVE OUR NEW TANKLESS HOT WATER HEATER! I looked at our electric bill after 2 months (March-April) of using our Stiebel-Eltron E-tankless whole-house water heater unit, and the kW usage actually DECREASED from one year ago for those same two months. That’s right, there was no increase in our electric bill. As expected, our gas usage decreased. My wife was very worried because she often ended up talking to the plumber issuing the dire warnings and predictions about our silly misguided endeavor to get a tankless unit. Now, she couldn’t be happier. Tandem back-to-back showers all day long, if we wanted. Never ending hot water! Thank you Maplewood Plumbing for helping us!"

"This is a good company to deal with. James, the owner, was out within one hour to diagnose our problem. The next morning the technicians, Brian and Josh were out to take care of our drain issues. Brian made a point of showing me the camera footage of the main drain. The did a great job on the main and two other drains. They also cleaned up very well when they were done. Brian also noticed an issue with our bathtub stopper and fixed it without an extra charge. The pricing was transparent. They have a nice email notice system and called when they were on the way. The three men I worked with were all very professional and easy to deal with. I would not hesitate to use them again. Phil Lykens"

Water Softeners FAQs, answered by experts

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.

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.

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.

Water softeners have many benefits. The most important one is converting previously hard water—water with too many minerals—to more usable, easier water. When we say easier water, we mean water that’s easier to digest, less harsh on skin and clothes, and builds up less in the water system. Softer water may lead to lower energy costs and will extend the lifespan of all appliances that use water.

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.
