Change in feedwater
temperature.
The reverse osmosis membrane used in your unit is
rated at 77ºF and 60psi. Water production will
decrease approximately 1.5% for each degree that
your incoming water is below 77ºF. It may be
necessary to change to a higher flow membrane
(and flow restrictor).
Storage tank pressure is too low. Check pressure with gauge and refill to maximum 8
psi.
Filters are clogged.
Replace Filters.
Water leakage at filter bowls
Filter bowls are loose.
Retighten.
