Tank Rinse Valve

[sdagro]

This is in regard to my '15 DSDP 4369. In my water/sewer hook up compartment there is a jinput for my black tank flush as well as a black valve that reads "tank rinse". What tank would this be referring too? Could it be a freshwater tank flush? Grey water? or do `I have 2 black water flush/rinse. Thanks in advance for any replies. Steve

The little handle labeled black tank is the line drain for winterizing or just releasing any water stuck in the line.


AKA low point drain for black tank rinse.

This valve is just next to the 2 low point drains(h/c) and is labeled tank rinse, not black tank. Does that make sense. This is why I am puzzled.

This is the drain for your black tank rinse line. To test it... flush the black tank with the hose connection, then turn the water off. Now open that valve and about a pint of water will pour out of the drain and then stop.

If you open this drain before removing the hose to the black tank flush, you will get a lot less water running into your wetbay when you unscrew the hose fitting.
