Dutchman, I know. We met each other a couple of years ago in a state park in the Florida panhandle. I was across the street and one spot down from you.
Happy travels. Maybe we’ll run across each other again!

Wow! How time flies. Your Outback in the foreground, ours in the background. Dec 23, 2015. We were at Florida Caverns State Park.

Nice to cross paths again!

Yep, that’s me. Off to Alaska on Monday.
Meet us at Glacier NP?

As 'O-B' says, the nozzle is the bad guy.
Sometimes they are held in place with a few screws and silicone . Getting access to the actual nozzle at the black tank can sometimes be a lot of fun. :M
If accessing the nozzle is difficult you could try to blow air using a compressor thru the line to the nozzle, as you would do when winterizing.

Also , I have an old hand held wand that I use every year to clean old my tank. The wand that we once used to flush our tanks.
I run a hot water hose to that wand and add DAWN dish soap in the tank. Once all the suds settle, I let it soak for an hour or two then drain (dump) it. That might clean it just enough to make it work again then give a blast of air again .


If you have access to the nozzle:
Either buy a replacement nozzle or soak and clean out the old one, you might need to use a small drill bit or wire to really clean out each port, they usually just get clogged up.

campigloo,

I replaced my outside connection for my black tank flusher about 4 years ago when it started leaking. Actually, my own fault because it cracked over the winter.

More than likely, when you replaced the outside connection, you disturbed dirt build up in the lines and some of it broke loose. Now that dirt (or skum) is blocking the jets inside the tank.

Either that, or your black check valve under your bathroom sink is installed backwards.

Either way, go under the sink. Look for the 2 water lines that come up from the floor. Remove the black check valve. Then, with a good shop vac, tape a hose to the line that flows into the tank and turn on the shop vac. This will suck any debris that might have broken loose from the inside of the pipes and suck it back out, also free up the nozzles inside the tank.

If you used any plumbers putty on the outside connection, chances are some of the putty might have oozed inside the pipe and when you turned on the water, it broke free. If so, it clogged the black check valve and its now ruined.

So, removed both lines from the check valve and try the shop vac on both lines to make sure they are free. When you feel they are free, then (I know this may sound awful but) try blowing real hard through the pipe going inside the tank and if it's now free, the air will pass. If not, it's still clogged at the jets inside the tank.

By the way, this is how I now winterize the black tank flusher. I remove the check valve and simply blow air into the pipe from under the sink.

I made the mistake once of using a hose in my yard that was laying on the ground and attached it right up to the flusher before letting some water run first, rinsing the hose out first. I immediately knew I made a mistake because the end of the hose had dirt on it. That little (tiny little bit of dirt), by passed the check valve and clogged up the jets immediately inside the tank. I freed them up using the the method I just described.

You can always revert to one of those Backflow devices where you hook up a hose to the device which forces water back into the tank. In an independent test, somewhere on the internet, that methos worked better than the traditional rinse method like you have and/or ice cubes!

The 'Spray nozzle' in the tank is clogged

The holes get clogged up with debris from tank and/or minerals from the water source

Some nozzles can be removed.....some are HOT Spun into the tank (high speed melts tank material).....some are glued
