REVERSE OSMOSIS unit makes water flow slow

When I put in (replace) the 15 gallon per day Reverse Osmosis membrane, I lose water pressure to almost a drip.
Is this normal?

It’s possibly one of the following three issues:

REVERSE OSMOSIS UNIT Makes water slow.
o Normal R.O. process.
- Your 15 gpd Reverse Osmosis water purification system makes water a drop at a time. 3 gallons storage tank should be full in 6 – 10 hours.

o Low water pressure.
- Increase to 50 psi. Check for kinked tubes.

o Filters clogged.
- Replace filters.

o Membrane not installed correctly.
- Ensure installation is correct.
