Water Purification System

We bought a water purification system at the Cottage Show. Paul was extremely knowledgeable and took the time to explain the system to us. We were so very pleased with the service we received. The system arrived when they said it would. We won't hesitate to refer friends and family. Thanks Water Store!

Finding someone who has first hand knowledge of the Viqua water filtration system was great. Difficult to find this level in BC. Worked through my problem with an existing system and resulted in saving me a lot of time and money with a replacement system. Thank you.
