Hard water, by the numbers

- Up to 48% less efficient: gas water heaters on hard water in testing.
- 1 in 3 homeowners replaced appliances or fixtures because of buildup.

Our take
The most common filter-change mistakes
After 20+ years and [thousands] of systems sold, these are the problems we see most.
Changing filters is easy, but a few mistakes cause most leaks: not shutting the water off first, pinched O-rings that don't seat, skipping the flush so the first glass tastes like carbon dust, and putting the membrane in backwards.
If any of that sounds like a headache, book us. If you'd rather do it yourself, our how-to guides walk you through it step by step, with video. Either way, the subscription makes sure the filters show up on time.
