manabloc supply lines too short

First, thank you to anyone who can offer help on this situation.

I have a manabloc in my house; therefore, I do not have any valves under the sink. I replaced a bathroom faucet last night only to find that the supply lines are about 4 to 5 inches too short to reach the bottom of the new faucet. The shortest extender (with adapter) that I could find was 12 inches.

My supply lines are pvc piping. How would I go about cutting these down a few inches and then re-attaching the fitting. The cutting down the pipe doesn't worry me as much as re-attaching the fitting (while keeping it leak-free).

I searched the forums, but didn't find a solution. I have read how to do this with copper piping, but with the pvc, I am unsure.

Any help is appreciated.

If you have a manifold system you had better NOT have PVC pipes. WE would have to see a picture of what you have in order to make a recommendation.
