Have you gotten onto your council and/or landlord about the water?
Nah didn't bother. The water is running clear again and I've washed other non-contaminated nappies without drama since! Other friends in town had similar problems and I saw a burst water main late last week so I think that dirt just got into the line we're on and I'm pretty sure they've fixed it now.

OP - If you want me to send you a sample just pm me hun. I ordered the sample pack so I'm getting about 7 sachets I think.
