Is there a safe and convenient method to flush the tanks

[holstein13]

In August, I'm picking up a new coach and the water compartment looks like this:

Here's a closeup:

The safe way:
Disconnect the coach completely from the city water supply. Use a separate dedicated hose to hook up to the city water supply and connect the other end to the gray and black flush. Disconnect everything and move on to the next campground when done. This would virtually eliminate any chance of contaminating my coach's water supply since the flushes will never be connected to my coach, but it's not convenient.

The convenient way:
Hook up a valve splitter to the coach's spigot and connect a small hose from the spigot to the flush port. This is super convenient because I can leave everything connected and just turn on the spigot whenever I want to flush my tanks, but it's potentially not safe.

My question to the forum is this, is there a safe and convenient way to do this? Maybe a quick disconnect and a better backflow preventer?

Your rig has back-flow prevention devices. If you still are concerned, buy one of these and attach it to a "Y", use a separate hose and relax.

Wow: glad that isn't mine. Aside from the header that allows you to shut off any individual faucet in case of service for a leak why would you need something that confusing? And most likely you can't add water to the tank by bucket if you need to. I have had to many times. No thanks, just an engineer needing work or get a layoff.

There are lots of RV's of all types without gravity fills, I have had two, no big deal.

I'm not getting the macerator. So take that out and that also removes the switch. It's not so confusing after that.

Haven't seen anything like that since the movie "RV" w/ Robin Williams.

Here's a better backflow preventer:

Also, keep in mind that you tank flush systems all have check valve/anti-siphon/back flow preventers....(or whatever you call them.)

These 'should' prevent contaminated water from flowing back into your hoses.

Get a Y connector to attach at the spigot. Leave your regular FW hose hooked up. If you're really paranoid, each side of the Y has its own shutoff so you can shutoff the FW to the coach but leave it connected. Attach a separate black or green hose to the other side of the Y, then the rinse connection. Open 'er up and rinse away.

I don't see a picture either but have to ask, Is doing the job the "safe" way really that difficult?

I'm not seeing any pictures.
