It is important to keep the permeate side isolation valve(s) open to keep the
permeate back pressure to a minimum during the flushing procedure
Feed/brine pressure should always be higher than permeate pressure to
avoid any membrane damage.
Flush each stage (bank) separately.
Do not re-circulate flushing water.
