Reviews for Rock Valley Culligan
Overall rating: 4.8/5

Very kind man installed my softener. She also hooked up my refrigerator and put a faucet in for filtered water on my kitchen sink. Everybody that interacted with me treated me with kindness. Very comfortable to have in my home.

Chris, my installer was really kind and personable. I found him very likeable and knowledgeable. He was in and out within an hour and made the new water system blend seamlessly within my current water conditioning machinery. 😊 Thanks.

Rock Valley Culligan is aways polite and gets the job done. We get six five gallons of water delivered each month with a family of five. We could not ask for better service from the delivery drivers or the workers who answer the phone in the office! Thanks Rock Valley Culligan!

Office personnel handled the request very well. Technician installed new system in short amount of time and provided a great install.

This place is such a pleasure to deal with. So helpful in every way. This is the ONLY water company I will deal with. Prices are reasonable and if you finance with them, the terms are so easy. So glad I switched water companies and found Rock Valley Culligan!!
