When to Book a Water Filter Service in Toronto?

Proper maintenance of your water filtration system is essential for ensuring the health and safety of your family or employees. Here are a few factors to consider when determining how often your water system should be maintained.

Time-Based Maintenance

According to the Water Quality Association, it's recommended that your water system be maintained at least once a year. This includes sanitizing and changing the filters. Over time, filters can become clogged with impurities, which can affect the quality of your water. Regular maintenance can prevent this and ensure that your system is functioning optimally

Inactivity-Related Maintenance

If your water system is inactive for 30 days or more, the water in the system can become stagnant. Stagnant water can lead to the growth of bacteria and other harmful microorganisms. To prevent this, it's essential to have your filters removed and sanitized. This will help to ensure that the water in your system is clean and safe to drink.

Usage-Based Maintenance

If your water system is used excessively, such as in an office or commercial setting, your filters will naturally start to clog faster. It's important to monitor your system's usage and have it serviced as needed to prevent clogs and ensure that your water is clean and safe.

Maintenance After Construction

If there is any road work, construction, or neighbourhood water-main repairs in your area, it can cause dirt and debris to get into your water system. This can lead to your filters clogging more quickly, compromising the quality of your water. It's important to have your system checked and serviced after any construction work in your area to ensure that your water is free from harmful contaminants.

Excellent product, product knowledge and top notch installation & service. This is a great company to do business with. Highly and most definitely recommend. I am so happy I stumbled upon WaterMart while I was out walking on Queen Street East in Toronto a few years back. No high pitched sales tactics with this outfit, just good old fashioned & honest product knowledge via 2 very pleasant and humble team members. My installation appointment was booked for the next day and I couldn't be more impressed with the care taken and the checklist left for me of what was done - replacing the old cartridge, installing a new one, sanitizing the faucet inside and out and checking the pressure, for example. The technician showed up 10 minutes early, took his shoes off at the door and thoroughly cleaned up after himself. The water is delicious. I will highly recommend this local business to anyone and everyone. Great service, Great product, Great find, Great price. They come every year to replace my filter and I am very pleased with the service and value.
