Smelly hot water . Why?

[Chris Pickering]

Thanks for all your replies.
Now tomorrow I'm going to sterilise my tank by draining it and using Milton's sterilising tablets.
Will that be good enough and can I also run it through my system to sterilise my tank as well?
If it's not good enough how and what should I use

Drain it, run some clean water through, enough to empty cylinder. Milton Fluid a safe bet, as used for baby feed stuff. Might leave a bit of chloriny tang for a bit, but not unsafe if mixed in the correct proportion as per directions.
I use Milton solution when servicing private water systems. We have a lot of property on non-mains water in rural Wales. Make sure your lid fits well and gauze filter on overflow and vent on lid.
