Iron & Sulfur Removal
Iron & Sulfur Removal in Daly City
Iron and odor solutions for wells and older homes across the north Peninsula.
Where the iron is really coming from
Iron and sulfur removal in Daly City starts with a question: where is it coming from? On private wells, dissolved iron, manganese and hydrogen sulfide can come up with the water, and an oxidizing filter removes them.
But on regional city water, orange staining usually comes from the home's own galvanized pipes, not the supply. In that case, a sediment filter at the main and, eventually, replumbing are the answer, not an iron filter.
Rotten-egg smell in only the hot water usually comes from the water heater's anode rod reacting with the water. Replacing the anode is often the fix.
How we diagnose it
We test both hot and cold water, at the main and at a tap, for iron, manganese, sulfur and pH. That tells us whether the problem enters with the water, develops in the pipes or starts in the heater.
Only then do we recommend equipment. Many Daly City homes with staining need a sediment filter and a plumbing conversation, not an iron removal system.
Inside Daly City, most orange staining comes from the pipes rather than the water. If your home is on regional water, the stains usually mean rusting galvanized lines, and sediment filtration plus a plan for the worst pipe runs is the sensible answer. If you are on a private well up the coast, iron in the groundwater itself is far more likely, and that is where a dedicated iron filter belongs. A test tells the two apart in minutes.

Questions people ask
Is the iron in my water harmful?
Mainly a nuisance: staining, taste and clogging.
Why only hot water smells?
Often the heater's anode rod.
Do city homes need iron filters?
Rarely. Rusty pipes are the usual cause.
What about a rotten-egg smell?
If it is only in the hot water, the water heater is the usual cause, and an anode change often fixes it. If it is in cold water too, the source is the supply.
