Question 1

Will rust stains from well water sprinklers come off pavers or concrete?

Accepted Answer

Yes, in most cases. Fresh iron staining lifts with a rust-specific cleaner made for concrete, since bleach and general cleaners aimed at algae will not touch a mineral stain. Stains that keep coming back after cleaning point to an ongoing iron source that needs filtering at the pressure tank, not just surface cleaning.

Question 2

Do I need a filter before drip irrigation if my well water has sediment or iron?

Accepted Answer

Yes. Drip emitter orifices are small enough that fine sediment and iron flakes collect and slow flow long before a standard spray nozzle would show any effect. A cleanable mesh or sediment filter installed ahead of the drip tubing is the standard fix, and it needs periodic rinsing rather than a one-time install.

Question 3

Does a water softener stop rust stains from well water irrigation?

Accepted Answer

No. A sodium-based softener is built to fix household plumbing hardness, not iron staining, and it adds sodium to soil with every irrigation cycle. An oxidizing iron filter, not a softener, is the correct tool for stopping rust-colored staining from well water.

Question 4

Why does my well water smell like rotten eggs or diesel near the sprinkler valves?

Accepted Answer

That smell usually points to iron bacteria, a slimy reddish-orange film that forms inside valve boxes and pipe fittings, not dissolved iron alone. It is a different problem from plain mineral staining and calls for a chlorination shock treatment at the well rather than a standard sediment or oxidizing filter.
