Gravity will keep water in the trap. For a washer you'll need an air
admittance valve beside the stand pipe if the waste water has a long
route to the main soil pipe tree. This allows air to be sucked along
with the washer water letting it flow smoothly so it doesn't make
noise when gravity accelerates it down from the second floor.
I did not know that gravity will keep water from evaporating over
time. Most drains are used every day. A floor drain might not be
used for years.
I don't understand why they make gourmet cat foods. I have
known many cats in my life and none of them were gourmets.
They were all gourmands!
I have heard of people pouring a small amount of oil into the drain--
not sure if it was cooking oil or mineral (motor) oil, or if it would
matter which. This would be especially for drains that are not that
easily accessable. Otherwise, if the drain is easy to get to, and gets
no normal use, just pour some water into it periodically. Water
evaporates- things like that are just part of maintainance.
When I was in Europe I saw laundry closets lined with the vinyl
flooring. The material was folded up the wall for a few inches and the
corners sealed with vinyl "caulk" that formed what appeared to be a
weld. I even saw showers built like this. I haven't seen a material
like this in the states. I know nothing about this material but it
seemed ample for the job at hand.
They sell plastic pans with sensors and pumps (similar to a/c
condensate/humidifer pumps), that lift any leaked water up into the
drain standpipe the washer uses. They also sell auto-shutoffs for the
supply valves, in case a hose breaks. Both recommended for second floor
laundries. TOH website probably has a link to brand names- they have
featured them on their shows multiple times.
Other thought- it does freeze in Cincy in winter, sometimes. Make sure
the eave you are using, and the route the supply lines and drain use,
are not subject to icing. I would not tightly enclose the washer/drier-
makes service a major PITA. You need some place to fold and put clothes
on hangers. A hanging bar and big table within 6-8 feet would make
laundry duty a lot easier. I have seen living-area laundries combined
with playrooms and sewing rooms and such, or even a den/guest room.
