Sulphuric head smell

[dbsea]

Despite religiously treating, pumping out at 50%, rinsing, more treating…changing the vent filter… my head smells not so great. Have the Tecma electric macerator, with sea water flush. It never used to be bad. How can I get a sulphuric smell from an empty tank I rinsed twice?? Btw this is all interior smells, not via the vent.

Check this thread about a fresh water flush with 20% vinegar through the raw water intake. It worked for us.
