"The way to prevent a sink/faucet hose from dripping where it shouldn't, is simply to have it drop down a bit before it goes back up to exit the sink. Think of a "u" shape, where one end of the "u" is into the faucet, and the other end is curving up before exiting the sink."
That's fine if one is coupling onto the faucet, and in tht case it wouldn't matter is the connection DID drip. I think what as meant here was that a quick connct be put on to the pipes UNDER the sink so as to free up the faucet while the machine is in use, Then dripping would be a problem.
"The other thing is, I don't know that there are any FLs that are designed to be wheeled around on casters like portables; the spin cycle vibration would tend to make them scoot around on the floor. In fact, if you're using temporary connections, watch out for the scoot factor; you definitely don't want the washer to pull its water connections loose."
One can make one of the casters a locking or non-swiveling caster. My KM portable is set up so that one of the casters doesn't swivel, and this holds the washer in place while spinning. The drawback is that machine only rlls easily in 2 directions. Making one of the casters a locking instead of a non-swiveling caster would solve this problem.
