I'm planning to install a new water heater myself (the old one is going bad). However, I only have about 1/4 inch to spare on one side where the stairs are in my garage. The old heater is 20" diameter, and the new one that I want is around 22". I have plenty of room on the other side to install it, but the location of the vent right now wouldn't be centered on top of the new heater.
It's the same vent for the furnance, so the main vent comes out of the ceiling and forks to the furnace and water heater. How easy should it be to move the gas vent? Do I just need to reduce the length of the forked piece?
Also, I'm guessing that the hot/cold water pipes aren't going to fit up exactly either. Is there a flexible type of pipe that I can use?
:wall:
Or maybe I should just buy the water heater that I really don't want that is 20.125"?

It depends on how much space between the top of the water heater vent hood and the inlet to the main vent. It also depends on if you use double wall or single wall vent. If you have the room you can use a flexible connector or perhaps an adjustable elbow.
Water connections are routinely made with flexible connectors as are the gas supply unless other requirements are in your local codes. You may also be required to install seismic (earthquake) strapping. Most areas require a permit for water heater replacement, especially gas-fired water heaters.

you can extend the c-vent with a bit more, inspect the inside of the existing to make sure there is no build-up, if there is any replace, all of it!! there are bendable/corrugated supplies that attach to the hot water tank tappings and have solderable ends on them, with these benadle supplies they have rubber washers so pipe-dope and teflon are not needed

An adjustable elbow like this:http://www.highlandwoodworking.com/index.asp?PageAction=VIEWPROD&ProdID=2225
should help with the vent offset.
Flex copper connectors are REQUIRED in earthquake country, but are NOT PERMITTED in some other areas. Need to find out from your local inspector what they require.
