Orange stains, black specks or a rotten egg smell? We trace where it starts, test the well, then fit the filter the result calls for.
Iron in a well arrives dissolved and only shows once water meets air: an orange ring back in the toilet days after scrubbing, rusty blotches on white laundry. Manganese rides along, leaving black specks in aerators, and red-brown slime in the toilet tank points to iron bacteria. Hydrogen sulphide is the rotten egg smell, and it slowly blackens silver and copper.
These filters are one part of well water treatment for York Region homes, and our post on why local wells carry iron and sulphur covers the cause.
Smell the hot and cold water separately first. A smell only on the hot side starts in the heater, and no well filter will reach it.
Before recommending a sulphur water filter, our technician fills two glasses at one sink, hot and cold, and draws a third at the pressure tank. Each is smelled at once, before the gas escapes. Where the smell sits tells us where it is made:
A filter chosen from photos of a stained tub is a guess. We test instead.
Drawn at the pressure tank, ahead of any softener or filter, so we read the well itself.
Iron, manganese, hardness and pH, and whether the iron is clear or already red. Low pH or iron bacteria change the media.
We draw the pressure tank down until the pump starts, then time the flow over a sustained run with the pump running. Backwash is sized to what the well keeps supplying, not the tank's first rush.
Treated water is tested against the raw sample, and the media service interval is set from that result, not a calendar guess.
All of these backwash to a drain. The test, the well's flow and the space decide which fits.
An air pocket in the tank oxidizes iron, manganese and light sulphur for the media to trap. No chemicals; suits moderate iron.
A mineral bed that speeds oxidation, useful when manganese comes with iron. Acidic water slows it, so pH correction may go first.
Metered chlorine or peroxide, a contact tank, then a backwashing carbon filter. For heavy iron, strong sulphur or iron bacteria.
Only for a trace of clear-water iron. More than that coats the resin.
If the smell is only in the heater, the fix stays there: a different anode rod and a disinfecting flush of the tank. If the cold side smells too, the gas has to be oxidized before it reaches the taps. Light sulphur usually comes out in the air-injection tank that handles the iron. Strong sulphur, or a smell that creeps back before each backwash, needs a chlorine or peroxide feed ahead of carbon. Carbon alone loads up fast on sulphur well water.
A common call from well owners: the softener still goes through salt, yet the orange rings are back. Iron has coated the resin beads, brine cannot rinse it off, and each regeneration restores a little less.
With the iron filter first, the softener only sees water it can handle. Fouled resin gets cleaned or replaced through softener repair and resin service, and a new water softener installation is planned with the iron stage, UV last if bacteria show up.
Each iron filter backwash can use as much water as a softener regeneration, or more. On septic properties it all reaches the tank and bed, so we set the frequency from the iron load, not the factory default, on a different night from the softener.
In finished basements the floor drain is often under flooring, so the drain line runs to a standpipe or laundry box with an air gap, and the valve stays off bedroom walls where possible. A condensate pump cannot keep up with backwash flow.
We give a fixed written price after testing and seeing the mechanical room. It depends on:
We fit these filters on private wells across rural King Township, Whitchurch-Stouffville, Bradford, East Gwillimbury and Georgina. Iron, manganese and sulphur vary from well to well, even between neighbours, so the test result picks the filter, not the town. Most of Holland Landing, where our shop is, is on municipal water; if your home there has its own well, the same testing applies. For Keswick, see well water treatment in Keswick, or the AquaTec Plumbing home page for everything else.
What well owners ask before a filter goes in.
We run the tap check, test the well and fit the filter it calls for, ahead of your softener.
