What type of Pipe?????

I am wanting to install (in my Garage) A pump, pressure tank, and a 500 gal tank for the water to my house. I was wondering what type of pipe I should use to conect all this, copper, steel, or PVC?


Thanks

I would use sch 40 PVC or PE pipe with insert fittings.

I would plan the tank to be easy to clean and sanitize it.
