How do I know if Silvia is working upto par? I thought she had been
dying and not spitting out enough pressure.
I have a pressure gauge but don't know how to use it, other than I put
it on the portafilter hit brew and water leaks everywhere and the gauge
doesn't change. Help.
Also, other test I can do to see if she is up to par.
Brew Temp: ?
Double shot in 25-30 sec right?
Brew Pressure:?
Amount of water coming out of portafilter w/ no filter basket: x.x oz
in ? seconds?
I just need a way to verify for sure if I need to replace the pump.
Thanks,

How old is it? THAT is one of the main considerations when looking at
to pimp your pump.
over 3 or 4 years?
And what's with the leaks??
tell me more!

When you say "leaks everywhere" can you be more specific?
A guess: You need to use a basket in the portafilter when you do
this, otherwise the portafilter body alone will not seal against the
brewhead gasket.

That can vary widely depending on the thermostats designed range,
where in the cycle you measure it, and more importantly, how you
measure it. _AROUND_ 190f. or above __generally__ means you are doing
OK as far as temperature goes.

it should be __ABOUT__ 70-80ml (2.5 ounces, +/-.25 ounces) in about
ten seconds.

Have you backflushed lately?
-if NO, then that can be part of the problem
-if YES, then that can be part of the problem
