Having clean and healthy water within our home is a top priority for our family. So, we just had our water treatment system installed by Culligan Water.My background is in the technology sector focused on creating memorable customer experiences through product design So, using that lens, I was impressed by the end-to-end customer experience provided by Perry Morin of Culligan Water.We have a new drilled well this year. The water was unclear and tasted bitter. So we had the water tested with two independent water testing laboratories. Culligan Water conducted their own water test, then sent out a sample to one of the independent labs that they trust. The test results detected bacteria, manganese, sediment, iron and hardness.Given the test results, Perry outlined product options along with the benefits of each. We decided to purchase the Aquasential Select Series Water Softener and Aquasential Select Plus Iron/Sediment Filter systems.Perry was very communicative throughout the process. This included explaining the installation steps, submitting proposal options, scheduling the work, and yeah, showing up on time.The quality of the installation with respect to the system layout, plumbing and water discharge lines were completed in a clean and professional manner. Many contractors don’t care about the appearance of how they install a system since it’s in the basement right. Yet, Perry consulted with me on how I wanted to layout the equipment and run the lines given we have future plans to finish out the basement. It’s secure, clean and professional.On many occasions, he took the time to explain, in detail, how the system works and showed me how I can monitor the status of the system through the control panels, even allowing me to video his presentation for future reference. He was a pleasure to with even while annoying him with lots of questions.We signed up for the quarterly sodium chloride maintenance plan, which is a great deal. Trust me, I did my research in looking at water treatment companies in our area before interviewing and hiring Culligan Water.In my opinion, they were the best choice, and I have now confirmed that decision. I highly recommend Culligan and Perry who rocks…best home investment we ever made.Paul
Charlie and the Culligan team came in and reviewed the water test after we had an Artesian well installed. They came up with a plan to handle all the issues including Arsenic, Iron and the usual suspect for hard water.Added to that we requested to have our outside water silcocks separated from the water softener, but wanted the Arsenic removed for watering the animals.The Team did an outstanding job And the finished price was more than reasonable.I would absolutely recommend Culligan of New Hampshire to any one in need of water treatment.
Thanks a lot to Charlie and the team for setting up a whole house filtration system. They did a great job, and saw it through even after it became clear the system they originally quoted might not be the right fit. They upgraded me to a stronger filter just to be safe, but they honored the original price. I appreciate that.
I had a great experience working with Charlie and his professional workers that installed my water softener.i am very thankful for calling charlie and getting good water .Thank you to the whole Team

Great experience with this company. Spoke with the owner, Don, personally and got some suggestions to fix my failing water filter system.

Usually, if your water smells like sulfur or rotten eggs, the reason is because your water has high Hydrogen Sulfide (H2S) content.

H2S is a gas that is released from the earth and finds its way into groundwater. It’s especially common in well water located near shale, sandstone, coal, peat, or oil.

(Occasionally, a rotten-egg smell in your water could also be caused by a water heater or by sewage pollution in your water. If you’re on city water, the most likely explanation is your water heater.)

A rotten-egg smell in your water may be strongest right after turning the water on, as heat forces the gas out of the water and into the air
H2S dissolves in water to create a weak acid that can corrode metal pipes

Negative Effects of H2S

In addition to potential health risks, having H2S in your water can cause all sorts of annoying problems. H2S in your water can:

  • Cause coffee and tea to be discolored and taste funny
  • Corrode metals (steel, copper, iron, brass), including silverware
  • Cause foods cooked with water to taste “off”
  • Create yellow or black stains in your bathroom and kitchen 

How Do You Fix It?

Here at Culligan, you can find everything you need to get rid of H2S and that sulfur/rotten-egg smell from your water.

The first step we have to take is to test your water, so we can be sure of the real cause of the rotten-egg smell.

Fortunately, here at Culligan we offer this service free. One of our water experts will come to your home to test the water (you can’t send it away to a laboratory because H2S is a gas and could dissipate during transport) and let you know the source of your rotten-egg smell. You’re under no obligation whatsoever. 

Culligan water treatment systems can completely remove the rotten-egg smell from your water
