Why It Matters
Your tankless water heater has a filter on the cold water inlet that catches sand, sediment and debris before it reaches the heat exchanger. We replace your system’s filter to help reduce debris buildup, support performance, and prevent unnecessary maintenance issues.
A clogged or damaged filter restricts flow, which can lead to weak hot water at the tap.

Common Questions
How often should the filter be replaced?
We check it during routine maintenance and recommend replacement when it's clogged, worn or damaged.
Can I add a filter replacement to my flush appointment?
Yes. It takes about 30 minutes and pairs well with an annual flush.
What does a clogged filter look like?
Sediment, sand or scale caught in the screen, like the filter pictured on this page. Reduced hot water flow is a common sign.
