(Studio City) -- Only in L.A. -- A water man breaks, and somehow, there's a celebrity angle.  When a valve for an 8-inch pipe busted this morning along Mulholland, the river of water flowed all the way down to Ventura Blvd. 

    Along the way, it filled Eddie Van Halen's pool with mud.

   Van Halen was not around at the time. He's said to be on tour with his band in Canada.  The Fire Dept. notified him by phone.

   We walked up the driveway to what used to be a beautiful pool.  It's hard to see where the deck ends and where the water is supposed to be now... It's just a giant mudhole.   The curly slide leads to a pile of dirt.

   No pool man or pool filter will be able to clear up this mess.  Eddie will need some heavy equipment to get rid of all the debris.

   Fortunately his home was undamaged.  Firefighters put sandbags around it to keep the water out.
