Whether your looking for a replacement RV sewer hose or need to outfit your new camper with it's first sanitation setup, we have you covered. But no matter what brand you choose, Blue Line, Rhino Flex, Smart Drain or Valterra's EZ Flush, if you do not use proper RV sanitation practices it may all end in a big mess. When emptying your RV's black and gray tanks, you always want to dump the black water tank first, allowing the gray water's soapy water to rinse the hose. It's always a good idea to ensure the black water tank is at least 1/2 to 3/4 full before dumping. This gives enough flow to keep your sewer hose from plugging up during the dumping process. You never want to leave the black water tank valve open when hooked up at a full hookup campsite. By doing so, it allows all of the liquids to drain, leaving solid waste behind to harden at the bottom of the tank. Keeping the length of your sewer hose as short as possible will also eliminate the chances of a backup. Having shorter sections to put together versus one long hose can be a good choice when camping at many different locations. It's always a good idea to wear protective rubber gloves or use hand sanitizer any time you are handling your RV's sewer hose.
