Sure, you can order repair parts online for those cheap RV faucets, but the shipping costs are more than the part. The first thing we did was go to Home Depot and buy some better quality faucets that repair cartridges are readily available for. The wife said those RV faucets (ABS plastic), belong in a doll house! We got some decent faucets with NSF brass. One is Peerless, the other a Delta. Both have lifetime warrantees.
