And your username is a homophone of a word used for the men’s room in a few English-speaking countries (loo) 
What’s wrong with the water that comes out of the tap - in the men’s room, even?
Guilt by association.
I don’t think the OP had a problem with water from the tap per se, just that the filter would be regularly changed on the men’s room floor.
Well, why have a water cooler at all, then?
If this is the biggest issue you have at work, you’re pretty lucky.
The company I work for has drinking fountains, and all of them are right next to (sharing walls with) the bathrooms. Should I be worried?
Yep, this is it. Water is water, at least pre-toilet. But having the filter system on our filthy men’s room floor is not cool. You have to remember the thing has to be opened every couple of months or so to change the filter.
if you use stretch film or plastic wrap in your lab/facility then go wrap up the filter assembly and stick a label on it.
Isn’t that the location of 98% of all drinking fountains? Woosh-bait?
This is a totally different set up.
I drink from streams, salmon die in them, and bears shit. I don’t know what to tell you.
Rugged. When I get giardia I paint with all the colors of the wind.
…well, mostly from the red and brown ends of the spectrum.
Carry ten pounds on your back or carry an empty bottle. Never have got giardia, I always felt I would change if it happened, but it hasn’t happened yet. Besides bear shit tastes good, like tea.
Or you could take a 10 cent chlorine tablet and drop it in your bottle of river water. Your call.
You guys want gross? We have an RV and there is side compartment down low where the stuff for hooking the RV up to camping facilties is located. You have a heavy duty power cord. And you have a flexible drain pipe that you hook to a fitting on the RV and run to the campgrounds sewage system. Mere inches from that fitting is the fitting for running a hose for fresh water hookup. And trust me, in the process of hooking and unhooking some sewage water gets spread around. I aint even a germaphobe and I think thats a BAD idea. I’d relocate that water hookup to somewhere else if the significant other wasnt an irrational bitch about anything have to with the RV.
