A few questions on RV gray and black tanks.

[Jeff in Ferndale Wa]

Thanks for the helpful response.

If that is the case, do you think it is safe for one more shower or should we have the tank dumped before taking another shower?

Thanks.

The worse that can happen is that the drain starts backing up and you have to cut youir shower short.

And make all your showers navy showers. What that means is:

1) wet down quickly then shut the water off.

2) Soap up all over

3) Rinse off quickly. Then shut the water off.

I’ve done it this way many times and found I only use about 3 gallons of water.

Could you kitchen sink drain be clogged or almost clogged? If that is true, it is possible that the gurgling could be caused by air being pushed out of it.

The tank was full. My wife took a shower and it stopped draining at the end.

That was how we showered. We strategically planned the routine beforehand.

This is what happened when my wife showered.

Quick update: We had the tanks emptied. I went to Ace and bought the cap with a hose adapter that Gary posted above. Our tank is now slowly draining in the drain that I included a picture of in the op.

Thanks, everyone.

No different than what a septic tank does.

That is very different than a septic system.
