I have a  2002 4100 Open and the Sealand head pump has an intermittent issue.  It became worse after a cruise with kids and I'm not sure if it's related.

Sporadically the pump used to come on for 2-3 seconds throughout the day.  After the kid trip, it comes on for several minutes and periodically won't shut off.  I have been flushing the head to see if it would reset and sometimes it works and other times I shut it off at the panel.  After several minutes off, I turn it back on and it stops running.

Is this a problem with the pump, accumulator, lines or???  Before I replace everything, I would like to know if you folks have had this issue and what you did to resolve it.

Thanks in advance,

Tim

That is the signal that you have a leak in the system.  Probably related to age of unit.  Take the kids off the hook.  Not sure how to diagnose.  YouTube?
