Rest area dumps and hose fittings

Could be the rest area dump stations that don't provide hose attachments for tank rinsing have limited storage in their waste water ponds. Rest areas usually are not next to a sewer line so the need to restrict waste water comes into play many ways, not just at the dump station.

Most rest area dump stations along the East Coast have been closed "due to budget constraints", anyway.

Barbed fitting attached to a short section of hose with male hose fitting that will attach to your flush device. Barb fitting should easily attach to hose with no fitting if same ID. Normally it will be the same ID.

In Calif. it is really inconsistent as to which rest areas have operational dumping/flushing facilities:( My choice is to wait until I get to my next RV Part site where I can take my time and do a thorough flusing. I can go about 8 to 10 days without filling up the black tank and need to dump.

Those free (rest stop) dump stations are just a courtesy...a place to dump and go.
They were not ever meant to be a place to flush and clean tanks.

Flushing and cleaning is for a payed for site or campground.

Where does this rinse hose everyone carries along connect to? I've never seen a regular hose bib type hook up at a dump station, it's always one of those water tower types, with the end cut off or otherwise non hose-able.

I carry my own rinse hose. :)

I carry my own rinse hose. I bought a short gray hose for the Santi-flush.

I've found almost all dump stations with a rinse hose have the hose end cut off. I asked about this at my storage facility and they said that it was an insurance requirement to do so as it lessened the chance of someone connecting to a potable water system. This seems silly as stupidity is rather ingenious.

I was told to bring my own rinse hose and I could do whatever I liked.

It's a time saving measure I think. The owner of the dump site doesn't want someone hogging the hole for 20 minutes filling and dumping and filling and dumping to "flush", or wasting all that water.

I don't know about Washington State, but in Michigan a lot of the dumps I've used have a nozzle / jet end on the rinse water hose. In Canada, the National Parks had a large rubber ball, so you avoided splash back while you rinsed your drain hose.

Save the flushing for the next time you're at a FHU camp site - then you've got your own hole and you're paying for the water and sewage... IMHO
