I highly recommend pressure gauges for each circuit in the panel or otherwise visible during all phases of flight.  It provides all kinds of useful information.  It improves trouble shooting and safety. 
For example, referring to the test described below, without gauges one doesn't know why the pump did not chirp initially.  -pull the dump valve - try again.  If the pump chirps, one can assume the system was pressurized and pulling the dump valve relieved the pressure.  Resetting the master then recharged the down circuit. 
Scenario 2:  If there is no chirp after resetting the dump valve.  Hmmm.  Is the system still pressurized (see Lorn's earlier post)? Is the pressure switch stuck?  Did the pump fail?  -bad solenoid etc etc.
Having gauges on board also provides useful data about impending failure, slow and developing leaks and any number of other ailments that might be cause for preventative maintenance.
It is one of those mods that is worth its weight in gold.

I can support that test from Lorn.  At HPAT I learned the same test in the Legacy.  Normally, I hear a short burst from the hydraulic pack when the MASTER is turned on.  If not, perform the test below and it has worked in my aircraft.  That tip came from the training session in Sebring recently.
