So, you do not want to collect the water from yor ac unit, go out, spend a dollar and get a 1/2 gallon jug of it and mix it with Hydrx w/c additive.
As stated before

There ya go
Also, the tubing doesnt need to be replaced for nearly a year as long as your power the system on at least once a week or so.
Its ok if you let it sit for under a month, but thats sorta pushing it
Also when he cuts the tubing, its not a huge deal to simply include an extra inch or two on extra slack so that if/when you drain the loop, you simply cut the tip off and then re attach it.
