Older properties, for example, may have to be tested for
asbestos and lead. For example, a microcrack in the turbine motor rotor or
elsewhere in the foreline section of the turbo pump that
traps enough air when at 1 atm to slowly outgas during pump down. Powering
up the Duo 1.5A and TC gauges, the system initially
would barely go down to 500 microns. After running
for several hours, it will get down to below 20 microns, and eventually below 5
microns. While the running time of the turbo pump for these tests
has been only 1/2 hour or so, the results are probably a positive
sign that the explored Universe is safe from destruction for awhile at least.
However, note that very small leaks (by the macroscopic standards most people are familiar with) can result in mediocre performance even for these low
to medium vacuum systems even if your pump can go down to 0.1 micron. For our
simple vacuum system, leak testing is usually self evident -
there are only a few places where leaks can develop.
Note that failure of a vacuum system to reach an acceptable pressure
even with a pump in most excellent condition may be a result of many factors,
only one of which are actual leaks (i.e., holes in the system somewhere).
For example a microwave oven repair specialist may
not be expert in fixing a gas oven repair. National Appliance Service employs expert

I have recently acquired a Granville-Phillips model
270 ion gauge controller via eBay ($60 total) and am in the process of
cobbling together a cable and vacuum plumbing to mount one of my ion gauge tubes
(yes, pulled out of the trash). An external leak is unlikely since the pressure would bottom out in a few
minutes, not slowly decrease over many hours. A high
foreline pressure will directly affect the ultimate partial pressure of low molecular
weight gases like hydrogen and helium due to their relatively
poor compression ratio. This increases the ultimate pressure by 1
or 2 orders of magnitude. No change. But I did notice that the pressure
was inching down (or perhaps, more correctly microning down!), just very
slowly. They allow kitchen and food preparation waste to be dumped down the drain and disposed of via the
sanitary sewer or septic system. However, the
idea of someone having dumped their Chinese lunch special
leftovers into the turbo pump doesn't feel right. Whether your
old Samsung Washer is giving up the ghost or just needs
a repair or service call, you can trust our friendly professionals
to do the job right.

Some companies offer metal doors, and some vinyl doors replicate traditional panel styles.
However, the consensus now seems to be that the slow pump-down is simply
due to water vapor that gets trapped on/in the surface of the metal parts of the system, particularly the vanes
of the turbopump with their large surface area.
We cannot refund special parts that are ordered. The foreline connections
are QF10 or QF16 clamped fittings with a long stainless steel bellows hose for
vibration isolation. However, I don't have a mate to the QF50 flange for
the turbo pump's Conflat to QF adapter but I had salvaged
a bunch of thick stainless steel plates from the trash, complete with
O-rings, that are close enough to the proper size to fit on top of the QF flange, clamped in place with 4 bolts.
