Muchas gracias por su buen servicioOfrecen muy buenos productos!!🙂⭐⭐⭐⭐⭐
This company seems to make customer satisfaction a very high priority. Last year on 10-02-24 they did the annual replacing of the numerous filters on their cleaning system at our house. Then they came by again on 10-31-24 to replace all the filters again due to the City of Laredo finding E-coli in the City's water supply. Culligan did not charge us for the replacing of all the filters in less of a month's span.Then on 10-08-25 Omar with Culligan saw that their water line was not connected to our refrigerator/Freezer and he asked if we wanted it done. Omar said there would not be any additional charges since it was supposed to be done by Culligan previously.We greatly appreciate Omar and Culligan. So many companies are dishonest and try to take advantage of customers not realizing the customers are going to stick long term with the companies that treat them honesty and fairly.

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
