The water softener was a great addition to our coach. But it requires periodic maintenance, to regenerate it every couple of weeks, and backflush it quarterly.

Backflushing it requires reversing the connections, to have water go in the outlet, and dump out the inlet. When I first backflushed it, I used the plastic double-female connector that came with it, with a couple of my quick-connectors:

Thusly:

On the output side, I didn’t have a double male adapter, so I just held the hose to my sewer connector, which was a bit messy:

I thought I could do better, so I bought some brass double adapters, which together with my quick-connectors, works much better:

When a test strip indicates the water coming out of the softener is getting hard, it is time to regenerate it (typically every couple of weeks, depending on where we are). This is done by pouring two containers of table salt into the top of the softener (after turning off the water, of course), then I connect a special hose to a sewer rinse cap, that adapts the water hose to the sewer hose, ensuring I can flush out the salty water without making a mess:

Here’s a closer look at the sewer adapter:

Another couple of pics of regenerating:

I also replaced the hose between the filter and softener with a more flexible one, and added a clear sewer hose adapter so I could see the water flow rate:

(You can also see the cap off the water softener in that pic.)

I do enjoy my plumbing bits. It may seem overly complex, but all those quick connectors and adapters make this required maintenance much easier.
