Black tank burst

Also, when I opened the basement (prior to cleaning) the smell was gone.

I just mixed 1 cup bleach to 2 gallons water & scrubbed the basement out. Rinsed with hose. Now 2 fans doing the drying.

A tablespoon (1ounce) of bleach (5.5 % calcium hypochlorite) per gallon of water is sufficient to sanitize even the worst of spills. Please dont flush a stronger concentration into a waste water system. It would kill all the beneficial bacteria in the system.
Water pressure is 29" / # of elevation.

If bleaching your carpet doesn't work (or sounds like the nuclear method?) try an enzyme based pet waste treatment like Nature's Miracle (red bottles) or Simple Solution (blue bottles)

Water pressure is 44 lbs/sq inch per 100 feet of depth. This is a constant it makes no difference if the column of water is 1 1/2 inches in diameter (typical vent diameter) or the water pressure at 100 ft depth of water impounded 30 miles behind a dam! It has to do with height only!

So to keep numbers simple figure that your RV vent is 10 foot long. That would be water pressure of 4.4 lbs/sq inch. Doesn’t sound like much does it!

However, years ago I also forgot what I was doing! And blew the top seam on my waste tank! I forgot the dimensions now but if the tank was 36 in x 48 in that would be 1728 sq inches times 4.4 = 7603# total pressure on the top surface of the tank! No wonder I separated the top of the tank!

This is why it blew a fitting seal rather than just running out the vent!

It did not spill inside 5th wheel (lucky). Blew seal around 3" pipe & broke.

Thanks.

This is what we use to clean up blood and other human wast in the hospital.

Surprised it didn't just run out of the roof vent. May want to ensure vent is clear.
