Need help with RO solenoid shut-off

[ldzielak]

Tony,

Water is not compressible and the pressure should be same no mater how long you lines are. I can't imagine you have enough air in the RO water to cause any spring effect that would cause a long delay. If the pressure is not high enough to shut off the solenoid, then you have a leak. The 1/4" line could also be flexing, but I have always had long lines, first installation was 20 feet, now I have 40 feet. No problems.
