A float on sink1 stuck and the lab lost the vacuum drains. This 
problem has been remedied however all the floats should be checked
and cleaned. This work will be assigned to Jules.

problem: alarm in CG1 going off too often
cause: setting in vacdrain 'black box' is too high
solution: due to lack of schmatics, the problem was resolved by altering
the zero setting of the vacuum transmitting gauge.  The alarm will now
sound when vacuum lowers to 10" Hg.  The sensors program had to be altered
as well.  It will now send email when vacuum is 13" or lower.  This should
avoid warnings due to daily flucuations, yet notify when a leak or other
failure is dumping the vacuum.

problem: vacdrain at 13 in. Hg and falling.
cause: leak in CG2 vacdrain tee (for sink1, sink2 & sink3).
solution: hoses cut and installed on a new tee.  sink3 valve fitting also
remade.
Air pressure was noticed when last connection made. Since vacdrain drop for
CG2 was valved off, pressure could be traced to leaking diaphram on air
valve on sink1.  sink1 put on problem report to replace valve. 
vacdrain system soon back to 19 in. Hg.
vacdrain system back up.

There are multiple problems with the vacdrain. It appears TCA from
GL-1 has caused problem with the system. Repair will require step
by step isolation. TCA use in the new lab will be discussed with
the Lab Mgr. The vacdrain is being looked at now.

The Busch pump in Rm 546 is at the getting close to the low oil
mark and will need oil added soon.

Busch pump problem moved to housevac. Not a vacdrain problem.

Replenished marble tank with 200 lbs. of marble.
(This load of chips was all that was in inventory.
 More will need securing the second quarter of this year.)

The 'gurgling' noises are attributable to the eductor
discharge hoses being out of water during the eductor 
'off' cycle.  The water vessel that should prevent this
is not liquid tight. This will be repaired.

Removed debris from LH check valve just before eductor.
The confidence level of this system is upgraded because
of this procedure. The vacdrain is up.
