black tank sprayers

I should now this, but I dont and am not sure where to find it. Trying to find out if our 2018 Whitehawk MRB 23 has the black tank sprayers that clean the tank out after use.
Insight or direction would be much appreciated!

Black Tank Flush

If you have them, then it would be located on the side of your unit near the city water hook up, water heater, etc. It is a regular hose hook up just like the city water hook up, but it has a label over it identifying what it is for.

Okay i must have them then, because I do have a hook up to flush the tanks on the outside of the trailer next to the city water hook up, just wasnt sure if they had the sprayers in the black tank that help clean it out. Must be all in one set up.
Thanks

That water inlet feeds the sprayer which is mounted near the top of the black tank.

First time you use it, look inside and make sure it isn't leaking. Some say that connection leaks from the factory. If so, it's just a loose clamp on a hose.

It's not always on the side near the city water hookup, etc. On my 23RB, it's on the rear of the trailer.

A black tank flush comes standard on the 2018 23MRB. The connection to your black tank flush is most likely located outside your tt near your fresh water connection. Connect a hose to the black tank flush connection when emptying your black tank. Turn on water to the hose connected to your black tank flush to run water through your black tank flush sprayer which is located inside your black substance holding tank. Water will spray into your black tank through the black tank flush sprayer as you turn on water to the hose connected to your black tank flush. This is to help clean out the residue inside the black tank. Make sure you open the black tank valve (connected to the sewer) when you turn on the water to the hose connected to the black tank flush in order to drain the water you are spraying into the tank or you will fill up the black tank and overflow your toilet inside your tt.

I know it not recommended, but I also close the drain valve and fill the tank a bit via the black flush, then empty and repeat. This helps rinse the tank even further, But you should never leave it unattended when doing this.

Same here.

I also have a shutoff valve where the end of the hose connects to the flush. If/when someone talks to me or I have to move away, I shut off that valve.

I like that idea. I too am guilty of closing the black tank and letting it fill a bit to get a good flush.
