I have dealt with Culligan for years with salt delivery for the water softener. Now purchased a water cooler with bottom loading. Love it😁 2/17/25 Having issues with water cooler. Tech comes it works, but in between it quits working on and off. I wouldn’t buy a bottom loader again.
Flexible delivery schedule. Friendly employees. Quality product.
On time service, friendly and professional personnel and always in communication with us in regards to deliveries.

On time. customer service. communications
Great and dependable service. Down to earth people with no pressure sales involved. Have been servicing our equipment for years. NEVER an issue or concern with Culligan. The only thing they could do better is to bring the donuts with the salt delivery (just kidding!). Highly recommend them for your soft water needs.
Tony with Metzners was like a scientist with all his vials, droppers, test tubes! It was very helpful to see the differences in water quality from different sources in my house.Thanks for helping me clean up my water.

100 % satisfied
Very friendly and dependable service. If you aren't home for a delivery (and feel comfortable doing so) you can leave an entry open for them,let them know how to get in, and they deliver and fill your salt tank. They also take care of your equipment (if needed) in a timely manner.
I have been a water softening customer of Metzner's for a couple of years and recently decided to add a RO system to our home. From the initial call, the consult with Tony, the install with Chad and the follow up visits Metzner's delivered exactly what they said they would. The consult was thorough, the install was professional and not only did they do an onsight follow up to ensure no issues / leaks; they also did a phone follow up to ensure I was satisfied. I strongly recommend Metzner's Culligan to anyone looking for a water softening or RO solution. Thank you!!
Excellent service and attention to detail.
Reliable and always conscientious
For many years have had reliable salt delivery and periodic inspections for my water softener. All good and no complaints.
Great service. Great water. No issues. Culligan is extremely professional and kind.We have had Metzner’s Culligan drinking water for 5 years. How many plastic water bottles is that? Saved. Handled. Purchased.We liked it so much we now have their water softener, which has also been working so much better than our other one that just didn’t meet our needs. (Kaukauna)
The reverse osmosis water tank is located in our basement. We have good tasting cool water all the time.
Very satisfied as they are so knowledgeable and very good to work with.
Will recommend them to everyone
Great service and excellent that they carry it down the basement steps for us!

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
