well i guess i should have mentioned that i live in an apartment and im concerned that over spring break my landlord might come in and do some maintenence work or something. and im not just paranoid, there is a good chance of his workers coming into the house. but theoretically, if i did let them go another week while i was gone, how could i get them water while im away? since i will be flushing them at this point it will be critical that i get them clean water.
