I'm not sure how the 2002 is plumbed but my 2003 is plumbed using both, pump #1 and pump #2 (breaker ID's), for the fresh water system for all sinks, fresh water wash down (located in the cockpit, starboard side, & Shower. See my post above. The purpose of running both is to minimize "pulsing" of the water at each faucet.. To test this turn pump # 1 off with pump # 2 on and see if water comes out of the faucets. If it does then turn pump #1 off and turn pump # 2 on. If water flows then its configured as I described in my previous post.. Both pumps are used for fresh water system...M2C
