Ok to leave the black water tank 1/2 full while in storage?

[precioustime]

We always try to empty our black and gray water tanks before heading home to our storage. At times it doesn't always work out and we end up leaving the tanks half full, no more, and put the rv in storage. It is not there for too long, 2 months max. It is in storage in Miami, not a cool place in temperature. We always drop in the blue packets of tank deodorants every time we dump and fill up again with 1/4 of water. Is it bad to leave the black water tank 1/2 full for 2 months in storage?

To the OP

No. Never leave it for that long. As mentioned, it will dry out, become a hard mess and you'll have a dickens of a time trying to get that stuff out.

I like to dump after every trip, but sometimes, after a weekend and there is no good place to dump, and I know I'm going out the following weekend I will let it "stew" for a week.

At the end of the season, when I know we are not going out anymore, I will pay at the campground near us to dump. There, I can use their non potable water spigot to flush the black tank.

In cases where I'm not paying for a service, I will not use the black flush if anyone is in line to use the dump station.

But to repeat, don't let a half full black tank, or for that matter, any stuff in a black tank sit for as long as you are suggesting.

Except when I've winterized I will always put a couple of gallons of water in the black water tank. When I've winterized, I will put some anti-freeze in the black tank.

Does your storage facility have a dump station? Mine does, and it can come in handy. Maybe look for a storage place that does. Or - bring it home and use your sewer clean out.

But no way would I leave it for 2 months.

Don't do it.

Before we full timed I did it once, tank was 1/2 to 3/4 full, put a 1/4 box of Rid-X in with some warm water. When I dumped and ran one flush cycle the next trip, the tank sensors work perfectly!!

That's gunna stink...........

[old_guy]

[AllegroD]

No!

Poop in your tank for an extended period in Miami, is that ok? You are kidding, correct?

[SidecarFlip]

PU.......lol

I saw a trailer one time at a dealer where the owner did not dump his black tank after his last camping trip. I do not know how long it had been since his last trip. The holding tanks are vented to the outside, so over time the liquid in the tank will evaporate. When that happens the residue in the tank turns into a solid block of poop.

I see that you live in Miami, I would be very careful about how long it sits.

I've done it on accident before and not had an issue. I would not do it on purpose, but, uh, **** happens.

2 months doesn't seem that long
Boats leave it in longer than that
Why not try something like Rid X?
But what do I know. Most people tell me i'm full of ..it anyway lol

[ScottG]

No!!!
A buddy of mine did that and ended up with a petrified layer of cement like stuff on the bottom of his tank after a month of sitting. It was VERY hard (and nasty) to break up and flush out.
You want to drain it completley before storage.

Your just gonna cause a build up on your tank walls. Sounds like a crappie idea to me
