We only buy our drinking water from here. Then 24/7 fill station outside is awesome since Im usually up at 4am doing my errands. The filtered water is the cleanest in town. I can leave it in a water bottle for two weeks and no musty smell developes.

I recently had a well installed, I took my water sample in for a free test to see what water treatment equipment I would need. Matt was excellent, completed the tests and determined my water was good and I didn't need any treatment, very honest. In the end, I bought a UV treatment system because the "banks" want it if you are selling your property and again, I found the price competitive and the equipment was good quality with a rack system that comes complete. I am a do-it-myself guy so Matt explained how to install and what fittings I would need for the install. Overall I was very pleased with

Still Water installed a water softener for my family in our brand new house in Port Perry. When I called Matt had the same recommendation as everyone else but some how the quote was way less then everyone else. Half the price of some. Installation was so quick, no mess was left and the final product looks professional installed as it should. I am glade I chose Still Water and would definitely recommend them to anyone.
