Also, I used to run the Skype app on my iPhone 4S and it really drained my battery towards the end of the day, so that's a concern too.  

If the hookups are done with metal braided hoses the chance for a leak at that point  is very unlikely.If you use a Washing Machine Pan hooked up to a drain under the the WD, even if the machine leaks or over fills, the water will not be a problem and not flood the unit. 

That's now three valuable days of marketing time down the drain.

Perhaps you forgot to swap out a 9V in the smoke detector after the last moveout, or perhaps that pesky drain pan went missing.

Butts wind up down the kitchen drain, and sometimes window sills are used as ashtrays. 

We have a drain field on 60 year old home that is "failing".  

If it's a smell issue then have someone remove the toilet and plug the drain line, you're going to have to get that smell out of there sooner or later. 

I supplied the new auger.

Even if the utilities were transferred, they can always go out.you should drain the pipes at the lowest level (basement) AND then shut the water down.you dont want to hold pressure in the pipes ..that's what kills them. also insulate the pipes before the shut off valve (assuming it is somewhere in the house) as they might burst as well. that's assuming there is no heat to the house. if there is heat provided ....do the same ..just in case.

I have seen people pull all the copper from the home and pour cement down all the drains because they were pissed off.
