Foaming water when boiling kettle…

[Star-Lord]

New water bladders - kettle just started foaming badly after a few weeks of no foaming. Is this just a case of should have emptied them a few times before use? Boiled dockside water and it’s fine. Will boil from other bag soon - but that one is quite full. They are new Plastimo 100l ones. P.S. I used a very serious water filter from Seagull (dockside filter) before I filled the new bladders.

Don't know what Plastimo currently recommend but last time I got one the instructions were to soak in vinegar before use.

Perhaps dosing might reduce foaming.

Personally, I put drinking water in a hard portable tub - mainly due to the taste that comes with flexible, but also because of the state of the bladder whenever I have the guts to dismantle and look at it.
