Trusted by homeowners
“I installed one on my home three months ago and can already see the difference after cleaning the tapware. The limescale used to come back after a couple of months, but after having the ActivFlo installed for three months now, I see no issues at all with limescale and calcification. A 20mm unit on our two-storey home doesn’t restrict the flow from what I have noticed. Highly recommended.”
“We've noticed much less calcification around taps and other fixtures, and the water has a softer feel overall. Installation was very easy—our plumber had it done in about twenty minutes. We're very happy with the product and have already recommended ActivFlo to others.”
