servicing the sewer hose

As said above, don't make it more complicated than needed.

Dump black first, then dump gray which is basically a lot of water, waterever you put down your sinks and some soap if you are using it while showering or washing hands. With bleach being hard on plastic, see no need to introduce the two. If still concerned, refill the gray tank with water and put a little dish or laundry soap down the sink and give it a second rinse from the gray tank.

Since I do a pretty large dump/rinse of both tanks, the sewer hose will be as clean as it will get unless I go at it by hand. If I really were worried about how sanitary it would be, I'd drop some bleach down the sink, fill up the grey water tank, and empty that.

What helps me with hose life is storing it in a plastic tub. Some storage bumpers can be very rough on the inside from rust.

From personal experience the only thing the Flush King would allow me to do would be dislodge a blockage fairly close to the end of the sewer pipe. Once the jet of water goes around a bend or starts moving uphill, you're losing force. You're certainly not going to refill a tank from the sewer end with one of those.

Make sure your tanks are full or close to it (both Black and Grey) then dump black first followed by grey. Dumping full tanks causes a lot more force of water "pushing" out the chunks.

Check it out on the camping world website but before you buy do a search for best price.

Flush King

I mostly dump gray tank last.

I buy Walmart's cheap ~$10 20' hose. So I replace mine every year or 2. Thus my hose always looks new, at least on the outside.

Maybe some soapy water, a little bleach, a soft brush or cloth mounted on an extendable pole. There's nothing wrong if you want to scour clean your sewer hose, but it is not a task my DW or I want to routinely perform. We try to keep the whole dumping process simple and flush out sewer hose by running a full tank of grey water through it followed by a quick rinse if water is readily available. The other thing we do (only when we dump at home) is to hang the sewer hose allowing it to fully drain and dry. We store our sewer hose, hose support, and various attachments in a small rubbermaid tub and don't notice any offending odors in our passthrough basement storage.

I rinse mine with grey water when it is used. And servicing??? Well, I don't service it, I just replace it with a new Rhino-Flex hose!

Don't make RVing more complicated than it is.
Dump the black tank first, then dump the gray water tank(s). This will clean out the sewer hose (all that it needs to be cleaned out).

Don't let your kits drink water out of the sewer hose, don't store your sewer hose in the frig or under your pillow..

Never felt the need to clean a sewer hose. Dump black tank first and then the gray tank. Quick rinse with fresh water if available, if not, no big deal.

Best way to clean out the sewer hose? Bleach? Soap and water? Advise please. Thanks!

With the gray water tank. Assuming your tank is fairly full that should be all that's needed.
