Including filter system and high-performance Rust filter.
Rust in household water often appears as orange-brown stains on sinks, tubs and toilets or as gritty sediment in faucet screens and washing machine filters. In many cases the culprit is iron oxide — iron particles picked up from corroded pipes, an aging water heater, or upstream plumbing — that settles out and discolors laundry or surfaces. Some homeowners also notice a metallic taste or cloudy water when sediment is disturbed after pipes sit unused. On Marathon properties, coastal salt air and storm exposure can accelerate corrosion, making this an issue for both municipal-supplied and well or cistern systems.
Because rust is solid iron particles rather than dissolved iron, it often shows up when water pressure changes, after main line work, or when water that’s been sitting in pipes flushes through. While it’s rarely a direct health risk, the staining, abrasive grit and repeated cleaning are aggravating — especially in homes around Seven Mile Bridge, Sombrero Beach area, or the Key Colony Beach neighborhoods where salt air can speed corrosion. The best plan is to stop those particles at the entry point so they don’t spread into every tap and appliance.
When rust is present as particles, the single most effective option is a whole-house sediment filter with a fine micron rating; it’s made to physically trap iron oxide and other suspended solids before they reach plumbing fixtures, water-using appliances, and showerheads. Installed at the main water inlet, this filter reduces orange staining, gritty buildup and clogged aerators in homes from Grassy Key to Duck Key, protecting laundry and fixtures throughout the house.
A depth-style sediment cartridge is often the better choice because it captures particles throughout the media instead of only on the surface, improving capacity and reducing how often it clogs. Picking the right micron rating is important — too large and rust slips through, too small and flow can be restricted as the filter loads. Mr. Pure Water in Marathon can assess your moderate-hardness water and property setup, recommend the right whole-house sediment filter, and install it so upkeep is straightforward; if testing later finds dissolved iron as well, additional treatment can be added without replacing the system.
