I am doing a complete remodeling of my bathroom. I have a couple of questions. I am replacing all of the plumbing is PVC piping adequate for the toilet and drain pipes. I am using copper for the water pipes. I will be replacing 99% of the plumbing in my house. Next question will using pipe help increase the water pressure? (I currently have copper). I live in New York City and during the summer the water pressure is not great. Will the larger pipe have any effect on my hot water heater? Also the drain on my tub was about 4 from the main I am moving the tub it will be about 7 will this be a problem?

PVC is good for drains.
3/4" will increase volume, but not pressure. Good move.
The cold water supply pressure into your water heater should equal the hot water pressure out.
Your tub drain line should be vented after the trap closer than that, but the drain distance is O.K. if you can slope the drain line 1/4" per linear foot toward the main stack. In some places, 1/8" slope is O.K., if you don't have room for the 1/4".
Check with your Building Inspection Dpeartment to be certain that you have all local codes (vary), permit, and inspections info.
Good Luck!
