[Shop-talk] Water pressure question

[eric at megageek.com]

OK, every morning for the past few day, when I take my shower I start with 
great pressure.
Then the water trickles to almost nothing, then the pressure returns.

I've added air to the bladder, but it didn't help.  What do I need to do 
to fix this?  Do the pressure switches go bad?  Is it possible to clean or 
service them?

TIA
