A year ago we used two gallons of chlorine to shock our 160-gallon IP 370 water tank and lines. It worked OK but we still have an off-taste/smell in the head sink and shower.
I followed these steps:
1. Emptied tank/lines.
2. Put an estimated 10 gallons of water into tank. Added two gallons of bleach.
3. Filled tank.
4. Let it sit for about 6 hours.
5. Opened galley and head sink taps and emptied system.
6. Repeated steps 4 and 6 until chlorine smell was gone.
One error, I think, was failure to run some water through the lines after step 3 so that lines would be full of chlorinated water. Also, I don't think I opened shower head when I was emptying the system.
Thoughts?
