My roommate ran over a 12" pipe. Now there is a lot of water draining from the inside. There is no water in the oil however. How do I find the water pump and hoses. I don't work on cars much, but I need to get it to hold water in order to get it to the mechanic. I'm hoping it's just a hose problem but I can't see where it is. Thanks! I sure would welcome any and all help.

Sometimes it's just better and cheaper to tow it in. You could cause more damage driving it now than there already is.:)

AMEN to the above.
Running "over a twelve inch pipe" can mean many things such as:
>did it puncture the radiator?
>did it puncture the oil pan?
>did it puncture the transmission pan?
You have a lot of "possibilities" which means that a towing bill might be real cheap compared to what driving it might cost you when all is said and done.
Sure, you could gamble - you could also draw to an inside straight when playing poker!
Some days you're the windshield - some days you're the bug.
