Customer reviews for Pentair Water Filtration are generally positive, with homeowners praising the system’s performance and water quality improvements. Some negative reviews mention higher installation costs or maintenance requirements.
Here’s what customers are saying:
“Water softener (installed) June 2021 in Southern Arizona. So far the product is working, hard water is a thing of the past. Shower, faucets, and toilets are a lot easier to keep clean. Salt (lasts) around 2.5 months. The only issue I have is the company sells you the unit but does not see how you’re doing after the sale. I would recommend this product.” – Ramon, Consumer Affairs
“Everybody was very helpful and patient. The job was done really great.” – Clinton, Consumer Affairs
“Completely lacking in any customer support. Multiple attempts to contact have resulted in zero or severely lacking follow-up on their part. I’ve contacted them numerous times, dating back to October of 2015 and have been very unimpressed with their level of care and service.” – Chris F., BBB
“Results provided from the (water test) kit are just what I need to upgrade our well water quality. (Resulting) information is clear and understandable. Obtaining (a) kit, taking samples, and returning samples were explained clearly and (the) process went smoothly. Thanks” – Phil H., Pentair
