Why Does My Water Suddenly Turn Rusty or Cloudy?

Water that suddenly turns rusty, cloudy, or starts smelling off is alarming, but it's almost always explainable — and fixable — once you know what to look for.

Rust-colored water usually means corroding pipework (yours or the supply line's) is shedding iron oxide into the flow, especially after the water's been sitting still for a while, like first thing in the morning. Cloudiness right after heavy rain typically means sediment runoff has gotten into a well, hill-fed, or gravity supply faster than usual. A sudden smell often points to bacterial growth in a tank or pipe section that hasn't been flushed recently.

In nearly every case, an outdoor master filter positioned at the point your main line enters the property catches this before it reaches your taps — that's literally its job. If your water has changed and you don't already have a filter (or your existing one isn't catching it), that's the moment to get a free assessment rather than wait for it to get worse.
