Reverse Osmosis - Plunger Use
Before using a plunger on the sink drain that the RO drain line is connected to, we recommend the following:
- Disconnect the RO drain line from the sink drain line.
- Plug the opening with 3/8" plug or other correct plumbing fitting.
- Have towel and bucket handy in case water comes out of the drain line connection when drian line is removed.
