Sure, and if it ain't broke, don't fix it. Actually, I'm kinda surprised that your original build was CPVC, as copper would be much more common. As Tony suggests, PEX is where you go, over time. Relax.
If you have a car dealer nearby who sells your daughters brand car, they have a dealer only master wheel key set. That's the good news. The bad news is you will need to have your car towed there as they trust no one with their master locking key set. They will remove your tire and replace the locking lug with a non-locking one until the company who made her original mails you a new one. What has to happen is the following: Upon your proof of ownership of the vehicle your dealer sends a computerized code directly off your VIN . The manufacturer springs this code to the company who made the original wheel lock. You give the lock company a credit card and you will have a new wheel lock within a week.
are you building a home made cannon of some kind? i suggested it to someone recently and told them to make sure they got pressure rated pvc. the fittings cost more than the pipes, especially if you're only getting a metre or two of piping. well, the joiners are only 3 or 4 bucks, but the end piece and screw cap can be 15 or so. don't forget the primer when you're getting the adhesive. i got pressure rated pvc and all the fittings from bunnings, but that was a while ago, and i think i had to shop around a bit to get the right sizes and stuff. so, are you a diy plumber or a budding spudzooka builder? orange cannon?
