If its an old heater the solids are probably built up above the drain and most likely are more like solid rock than minerals now. (?)

2018 Cruiser RV funfinder plumbing - what are the 3 drains under the camper?

On my rv they are low point drains for emptying the lines before winterization. Blue is cold water and red is hot water. There should be valves somewhere near them. For normal operation the valves should be closed. Sounds like one is partially open or leaking.

Why did black tank water come up in my shower

There is a "sacrificial anode" inside of a hot water tank, electric or gas-fired. Its purpose is to corrode at a high rate, in order to protect the rest of the heater from corrosion,

All hot water tanks (save the plastic ones)corrode. It is a given,

The sacrificial anode is usually made of zinc, or a zinc/copper/other alloy. When it gets eaten away from electrolysis (the action of minerals in the water, and the metals components of the hot water tank/heating elements/etc make the entire unit operate as a small battery), it usually turns a nasty, crumbly black.

It will leach into the water, and if enough chunks fall off the anode, it will color the water as you describe.

The SOLUTION, to "FixYa", is to write down the model number of your hot water tank, go to the local Home Improvement store (or and order a new anode. Replacing it is pretty straight-forward: turn off the water, turn off the heater, drain the tank down a bit from a faucet that is lower than the top of the tank (or the valve at the bottom of the tank) , remove and replace the old anode with the new one (it screws into the top of the tank, and is a large-headed "bolt", maybe an inch-and-a-quarter across).

Now that I have written this tremendous missive, I re-read your question/problem and see I missed the mark.

You have "black water" backing up into your shower.

You've plugged your sewer line a bit. Quit using so much toilet paper, you have a near-stoppage of your line. Pour a bottle of Liquid Plumber (or two) down the shower floor drain, let it sit for a number of hours, and then run hot water down the drain at as fast a rate as you can before it starts backing up to clear the clog.

Your use of the term "black water" makes me think you might be in a RV (Recreational Vehicle) or the like, so your problem may be cold-weather related. A heat-gun or hair-dryer ran along the drain lines (or a big heater aimed under the RV for a while) might unfreeze the clog and allow it to pass into the holding tank or sewer line.

Your "Black Water Tank" may simply need to be emptied, too.

Flush more often (important!), use less paper in each flush, eat less beans, and try to p**p in the RV public restrooms more.

Even so, if your are in an RV, the sacrificial anode in your hot water tank is good for only two years, tops, before it fails and your very expensive hot-water tank starts to leak. Fix it anyway.

Black water,fresh water and gray water gauges are way off.

You have the question we are all asking.
rv tank gauges never seem to be very accurate. The best you can do for your black water tank is to try to see where the sensors are mounted and try to spray water on them to loosen any gunk.
I have had 4 motor homes and never had very accurate tank indicators.
Your black tank can be checked by taking a flashlight with the water off and looking down the hole of the toilet. When it gets close to the lowest part,of the drain hole it is time to dump.

Cannot find the water pump to winterize 2010 Forest River Sierra. I can hear it running but am unable to locate it. The bypass valves are in the correct winterize position but the antifreeze will not go in...

You don't need to find the water pump. Make sure your water tank is empty before adding RV winterizer to the water tank. Run each faucet in the RV with bypass valve NOT in winterize position until you see the antifreeze begin to come out of the faucet. Do this for both cold and hot water side for each faucet. Then move bypass valve to winterize position and run for a few seconds.

Water inside basketball support

No, the automotive antifreeze is acidic, and will eat through the thin plastic.
A better option is RV Antifreeze - it is PINK and available at RV centers. You will need at LEAST 2 gallons to have the correct mixture.
Better option - empty it out, and fill with sand.

Water empty light wont go out

the black wire that was moving water from down condenser to up - water container - remove it. Use cotton swabs to "clean" the holes, do a run of the dryer without that black wire connected ( carefull, cause some wated might spill at this point), reattach black wire, and enjoy :)

It worked for me anyway. ( fingers crossed, its been on for 20 mins and still no red lights flashing)
