Any plumbers out there? My to-do list this past holiday weekend consisted of replacing the tank internals of a couple of our toilets this weekend. Easy job and not too expensive. But here's my question: The inside of my tank says the water level should be 5/8" below the top of the overflow pipe. The instructions that came with the new flow valves said 1/2" to 1". In an effort to conserve and reduce water usage, I adjusted the floats such that the water level is 2 1/8" below the top of the overflow pipe. Am I breaking some code/regulation or otherwise creating an issue in doing this?

I don't know about your local plumbing codes. However, the only thing that I can see happening is you're not going to get as much water flow into the bowl when you flush. You may get more frequent plugging of the drain with the reduced water flow.
According to my math, the adjustment conserves 0.6 gallons of water per flush. Given the number of flushes a family of four makes, that's a lot of water saved over the course of a year.
You're slightly changing the amount of pressure the water flows/flushes at. The correct way to adjust flush time/volume is with a new flap valve such as this http://www.fluidmaster.com/index.asp?bhcp=1.
When I had my flush valve adjusted too low, I would get frequent clogs, and lots of double flushing.
This was my tenant's unit, so that wasn't going to work.
I adjusted the valve to the mark on the inside of the toilet tank labeled "water level", and haven't had a problem since.
A toilet needs a certain amount of water to flush, if you reduce the amount of water it isn't going to flush as well.
I recommend throwing out all the floats, and converting them to a flush valve. Much better technology, and some of them will turn the water on more softly to reduce water hammer.
A flush valve is a 6 dollar part..

If the chunky flows, let it go
When they won't go, adjust the flow
When they won't go, adjust the flow
Good reads, I have an 80 year oil toilet in the basement that is in need of some new internals. I'll look for that flush valve stuff..

The parts I used are those shown in the diagram at that URL. Same fill valve, same flapper, and same handle too.
I do like Errtt's advice too.
