you're closer 
If you can come fix it, I'll give you some new nomenclature.....
Well you asked, and I thought I mentioned this long before now, but maybe just time for a refresher course.
I am engineer for this place:
http://www.zengelercleaners.com
In english means I'm responsible for the properties and everything in it, including ALL the locations, repair and maintainance of all the machinery, etc..
Some pics you won't find on the website:
The boiler room, to give you a sense of scale, you could park 2 fullsize suv's in that room where the boilers are.
The laundry area. From left to right, a 50lb machine, (2) 300 lb machines. 125 lb machine. Dryers on the far left, 6 capable of 100 lbs each.
The dry cleaning room. Dry cleaning refers to the fact we don't use water. It is a wet process, but the liquid is more like a stong mineral spirits. Biggest advantage is that it will not cause damage to water sensitive articles. It's also much more colorsafe. The machines open are the 'washers' both 300 lbs each, and the blue thing is a row of 7 solvent reclaiming dryers. We run usually 8-10 loads a day thru this room.
Shirt pressing department. There are 7 stations there an 8th in the planning stages right now. All that white pipe is PVC, all of which is my doing.
Along with this is an entire upstairs of 22 pressing 'stations' (multiple presses) for the drycleaning after it's been thru the cleaning room.
Probably didn't ever think so much went into it, hm? We have over 100 employees.
And yes, I certainly know plumbing. Absolute job requirement, as I just installed one of these on one of the boilers:
It's a valve for 4 incch diameter pipe, and it weighs approx 250 lbs, that was a fun Sunday afternoon.
The reason I asked was simple out of the three types of pipe I mentioned, PVC is the worst to fix leaks with as it is usually a one shot deal, put the glue on stick the pieces together and that's about it. They do have a glue 'dissolver' but usually it messes the pieces of pvc too.
