I would go for at least 150 gallons.

We did a pressure test like that and the plugs didn't hold.  20 or 30 gallons of water on the first floor into the basement. 

Paint is about $25 a gallon, or 5 gallons for $100.

Storing a 50 gallon tank of hot water in an Alpine winter garage, is a lot more expensive than you may realize.

When I went through the numbers on water/sewer it was apparent that under our "stepped" billing I was routinely leaving about 7000 gallons or more of water unused until the next price step.So I went down to $2 a wash and $2 a dry.

I've looked at the daily usage online and it shows certain days where anywhere from 900 to 1500 gallons are used in a day, then normal for a week or so, then bam, another big spike.

Don't buy level 1 granite, get something high end, or nice quartz.I don't know that buying a $75/gallon bucket of paint matters to the buyer.

A 5 gallon hot/cold water dispenser. 

It's probably a different mindset than where you're from, but here most people don't mind.Your water bill is probably a combined water/sewer bill, so every gallon that goes into your lawn is a gallon charge for the sewer system that you're not actually using. 

Had another unit where we were doing final touch-up paint and the contractor spilled a gallon of paint.
