[Arctic Fox]

Good morning,

I have an under-the-sink reverse osmosis drinking water system - Whirlpool WHER25 - which recently started providing just one glassful before slowing to a trickle.

I have replaced all three filters (pre, R/O and post) and flushed the system for 24 hours, but no change.

Manual says try repressurising the tank, but gives no clues as to how this can be done (and Whirlpool helpline only covers major appliances!)

Any thoughts?

Thank you
