Are You Concerned About Water Chlorination Or Trihalomethanes (THMs) In Your Water?

Trihalomethanes (THMs) are created from a chemical reaction between water and the chlorine used to disinfect it. You should not drink water with a high level of THMs. This article explains some of the health risks of trihalomethanes, including reproductive problems and cancer. Drinking water in many communities in Raleigh & Triangle is treated with chlorine or chloramines, which could lead to the production of trihalomethane (THMs) as well as a bad taste and odor. The bad news is that you definitely do not want to be drinking THMs.

Excellent experience. Installer was great and water feels so much better. I would recommend them for any water issues you may have.

Zach A. Was the best! He came in and really made us appreciate what the company does. Looking forward to starting services down the road!
Triangle Water Services is so helpful and a pleasure to do business with. Everyone that answers the phone is so helpful and understanding of your situation.

Tom was friendly, knowledgeable & informative- giving us options forour water issues which are high iron content- red staining on tub tiles & un drinkable hard water.We purchased a new softener & RO - let’s see what happens, but my confidence in theproduct is high at this time due to the thoitogh explanation by Tom.
Good service. No more trips to the store and buying bottles, time saved is nice.
I have used Culligan for years. Have always had excellent customer service with professional, knowledgeable people.
Jason was very friendly and helpful.
Great staff, honest and sincere business. I would highly recommend them
I give Triangle water 5 stars! After researching a couple of other water companies, I found them to be the best. I spoke with Zach, who explained everything thoroughly. He was knowledgeable, kind, and honest. Everything that was told to me was exactly what it was. No extra hidden fees. Excellent customer service. The gentleman that came to install the water machine was also great! His name was Will. He was promt and did not take long at all. He also explained everything thoroughly. I was very impressed with this water company and I am glad we went with them. The whole experience from start to finish has been great.
This company is great and I love their filter products!
I could not be happier. Our delivery driver is amazing. He calls me if I forget my bottles, and is the kindest man. They give us a schedule and come like clockwork. Great service, good communication.
Phoenix is great, super customer service, friendly and efficient. Give him a raise…. Just don’t raise my service bill 😀 👍 👏John McNulty
Requested a filter change with Culligan because we had low water flow. Josh came out and fixed it quickly and answered all my questions! Friendly, professional service!!
Wow. Chris and Josh helped us out on our new water softener and I couldn't be more pleased. They did not try to over sell us and gave us the straight story. Josh's install was flawless.
Sean and team provide exceptional customer service!
Josh was very professional, explained what was needed and why. Thumbs up
Josh was professional, knowledgeable and efficient!
Rating install of new equipment and small fix to existing system Josh was great. Friendly, knowledgeable and quick. Explained and demonstrated everything and went over repairs. Simplified the plumbing.
I was not expecting such wonderful service and professionalism from Montrell, the technician that came out and did my service for my establishment. I would definitely recommend this service to my colleagues! Such a great job!
I had Montrell and he had great customer services. He took his time and was very patient with me, I would love to have his help again and thank you Culligan!
Leaving this review for my technician, Montrell. He was very professional, worked quickly, and very efficient.
I had Trell come out recently, he was quick and professional. Gave me a detailed solution and what caused the issue in a way that was easy to understand. Didn’t feel like he was trying to get more money out of me like i have had in past experiences.
Shawon did a great job!
I have always been very picky about how my water tastes and what is in it!!! Several years ago I purchased a condo with a Culligan system installed in it and after working with this company I know I will never go back to NOT having Culligan service. I moved to the Raleigh area a year ago and before I moved in, I called and set up service. Montrell was my first contact and every time I have called since has been exceptional in his customer service. And my delivery technicians - Craig and Andre - the same. Recently, I called to inquire about smaller bottles because I am physically unable to lift the 5 gallon bottles. Even though the answer was "no" Montrell helped me resolve this problem within minutes. I was totally impressed with his determination to help make me a satisfied customer and am very grateful! I highly recommend this company.
Do to running a business out of a building built about 30 years ago, I needed a quality water solution for my customers and employees. I've had two Culligan water filtration dispensers installed at my business for years. Jason assessed our needs and setup our account. Skylar is the gentleman that performed the installation, such a nice guy and was in and out with zero issues. Communication has been perfect and invoicing is a breeze. My customers and employees are satisfied with the quality of the water and I'm very pleased with the service thus far. Thank you guys for everything!!
I tend to look forward to quarterly deliveries, relying on Sean's help with keeping this nearly 20-yr old equipment at top performance.Today's salt delivery, timer resets, and brief chat re salt consumption went even more efficiently with the assist by Sean's trainee, Andre. Friendly and courteous, Andre moved with a quiet swiftness. Looks like the team is drafting another winner. Thanks, guys!
Josh is a great tech! Very helpful and installing the new filters and explaining the process. Highly recommend Culligan to anyone interested in pure filtered drinking water!
I cannot recommend Triangle Water Services Culligan enough.
This review is for my Technician, Sean. His service is outstanding, prompt, knowledgeable and professional. The best!! And my dog loves to say "hi" and get rubs.
I’m very particular about my water, so I know I can count on Culligan. I just make a call to Montrell, and he gets me set every time. I appreciate it!
Culligan Technician Josh was thorough and considerate when he serviced our Culligan tank today. He helped to clean up outside debris that tracked in when he used a dolly to ferry an incredibly heavy tank to and fro in to our basement, too.
Montrell is always professional and very knowledgeable. I highly recommend Culligan water.
No complaints, really good service. Montrell was very helpful with great customer service & communication.
We have had great success with Culligan! We have used their water systems now for 26 years. They have kept us running all these years. Josh, the technician that calls on us is very knowledgeable about the water system and is very easy and nice to work with. We would recommend them as your next water system company. Tom and Sue Shamblee
