You are probably replacing piping that looks like this
You may have resolved this issue since August. However, yes CPVC pipe is ok for usage in hot and cold potable water distribution systems. Running CPVC pipes at lengths mentioned in your question should have horizontal supports at every 4 feet. Metallic pipes ran at those lengths, then it would need support at every 6 feet. Here is a little more information with Chlorinated Polyvinyl Chloride (CPVC) that affects the residents of San Diego. CPVC was not popular in San Diego because at the state level, California did not allow for it's usage until 2007. Some of the benefits of CPVC include a lower material cost compared to metallic pipes, a lower labor cost to install the product, a higher heat retention, a much quieter system, will not allow for scale build-up and does not corrode.
This product fastens together much like the PVC uses for outdoor sprinkler systems in which a primer cleans the pipes and a solvent cement makes the bond. The pressure rating of this piping system is 100psi, anything in excess could potentially fatigue the joints. In San Diego, pressures in some areas can exceed 100psi and do so very often. To combat this a pressure reducing valve is installed usually right above the shut off valve to the home. The sole purpose of this valve is to reduce the pressure down to a comfortable setting of 65psi, Uniform Plumbing Code will allow up to 80psi.

No not recommended. PVC is a pluming pipe ( drain type, very little water pressure ) If you are looking for something that is easy to work with and will pass all codes and regulation then PEX tube is the best. They comecolor coated and are really easy to hang, lay and fit to fixtures. Good Luck

First you have to see if it meets the local building code, otherwise you'll just be wasting mone by having to redo it later. If it does then you need to install it according to the newest code adopted by the AHJ (authority having jurisdiction). Most require 3/4 inch pipe up to the last two fixtures which can be 1/2 inch.

CPVC is considered Hot and Cold Pipe. It will work fine for what you have described. Be sure and strap it or hang it. The pipe will sag if not strapped.
I built in a large commerical building in Galveston in 1984 and was surprised to see that all piping by the local plumber was CPVC. I was and I am used to Copper, but it has been displaced by PEX.
CPVC should work nicely. Clean all joints and use the correct cement.
Good Luck!
