I have a submersible pump installed at my hometown - Gonda in UP. The water comes out good if we use the running water while the pump is running. However, the stored water turns to brownish red after 10 mins. It also leaves a lot of sleuth ( brownish red ) on all the buckets, tap and shower head. We are using RO to filter the drinking water. How can I treat this water to rectify the problem. Can I add a filter before the water hits my storage tank or to the pipeline from the tank to my pipelines? Thanks Amol.
