A few days ago I flushed the black tank of our coach; something I’ll do regularly.

I added a splitter to the campsite faucet, and a second hose from the splitter to the black tank flush on the coach; this green hose is for utility work like this, not for drinking water:

Here’s a closer look at the tank flush connection. It simply sprays around in the the black tank, to clean any debris off:

On Saturday we were planning to spend the day out-and-about (see a future post), so decided it was a good time to also sanitize the fresh water systems. This involved adding some diluted chlorine to the fresh water tank, running it through the various pipes, and leaving it to sit for several hours:

We used an inline chlorine chamber, that took undiluted chlorine, and diluted it while filling the tank:

We filled the tank completely; the first time we’ve seen the level monitor at 100%:

When it is completely full, it starts to overflow, so we shut it off:

Once we got back from our day out, we drained the tank through the faucets, to eliminate the chlorinated water, then filled and drained the tank twice more to flush out the remaining traces of chlorine.

We also replaced the (rather gross looking) water filter:

And the fridge water filter:

The water is now sparkling clear, odorless, and tasteless, as it should be.

We’ll repeat this process every six months, or sooner if needed.
