I have seen 3 and 4 inch sizes being used.

Any NYC broker will tell you that people are already starting to move back to the city, that's why the rents are going up and selling prices are inching higher everyday.

Use 6 inch thick or get City requirements. 

So basically i assumed my water bill would be pretty low and all would be fine. 3 months in, the floor starts to split in the living room (a huge wave in the floor that developed quickly and was 10 inches tall at its peak) and people are commenting on how it smells so musty/moldy in my house.

I did work for them in California and they own almost every storage facility.While operating a public storage facility sounds like it is easier to manage than housing rental units the business comes with inherited problems i.e. 24/7 management, theft issues, issues regarding damage to your customer's personal items caused by leaks in the roof, flooding of the storage yard and maintaining the asphalt driveways and parking lots is often very expensive and can take several years to recover from.I do underground utility installation and repairs for sewers, water mains, electric, etc. and I recently completed a job for Extra Space where we had to replace 1200 feet of 6 inch fire water piping.

Every inch of you should look like you're making it in the world.The problem is that most agents actually mistake the trappings of prosperity for the substance.

I ended up buying an actual wood transition piece since they were thicker which may solve your problem if you are only talking about 1/4 an inch. 

An agent and investor that is awesome someone who would know more needs and wants of some greenhorns trying to get the ball rolling inching our way closer and closer to our current goal of getting our first deal.

Basement is a messier project and could run you tens of thousands just for the underpinning especially if you need to make up 5+ inches.
