Who Has A Berkefeld?

[Lightspeed]

Cheers Beardyman,

The black filters are too expensive for me. I@m not worried about fluoride.

If you coudl do a repeat freeze thaw test on an old and saturated element that would be realy helpful. Thank you.

You've now guilted me into going off and doing some more research to see if there is any manufacturer guidance on the freezing issue. I'll report back what I find.

But please, if you can find the time, it would be really useful to know what happens in a real life freeze/thaw test.

Cheers,
