Rookie mistake. Tell me I haven't screwed up !

[AirEPotter]

This will go down in rookie hall of shame. I was preparing to blow out water lines and I hooked the air hose to the sewer flush (2 inches above fresh water inlet) instead of fresh water. I ran air for probably thirty seconds before I realized mistake. What have I damaged!!?? Ugh.

You might have damaged nothing. I used to blow that line out all the time on my SOB. It leaves traces of water in it that needs to be drained too. Unless I am missing something, I don't think you did any harm. In fact, that line needs to be blown out as well.

I am not familiar with your unit but there's bound to be a large volume of space in the line you connected to. And the line is then connected to the black tank and that's certainly a large volume of space.

So I'm guessing you did not damage anything. In the 30 seconds you were attached you probably did not build up much pressure. Think of airing up a completely flat tire - it takes a while to actually start building up pressure.

No guarantee... but you may be okay.

Fill the black tank with plain water adding a little food color to it, so that you could trace a leak, if necessary.

Red works well.

That will positiviely answer your question, not a guess.

I would think it went straight out the roof vent.

That's what I was thinking too. If that is plugged it would come out the - oh my gosh, have you checked in the head yet?

Nothing inside! Thank goodness. No visible signs of any problems at all. I'm just not sure where damage could have occurred-- if at all.

IF anything was damaged,

the most likely bit would be the back flow/check valve which is IN that line.

it's usually at a HI point U bend behind the lav sink

and before the line connects to the sprayer head IN the tank.

this valve is prone 2 leaking and spontaneous failures anyway,

but it's unlikely the actual btf head has split from the tank/hole.
_______

2 ways to check for damage...

1. hook up water to the btf, turn it on and go inside looking/listening for flow or leaks near the lav sink.

2. sniff around under the sink or in the lav area over the next few weeks for black tank odors...
_________

while i don't recall ne1 reporting THIS specific flub (kudos 2 U!)

there are dozens of threads on the btf and the problems with the check valve...

many pics of it, where it is and so on...

"btf"? Remember, I'm a rookie! Thanks.

The air should have gone right out of the tank vent and caused no damage. I would think that blowing out that line would be part of the winterizing procedure.

My trailer does not have that option and i don't winterize either...

When you blow out with air, just use the air blow gun and a rag with light pressure to seal the opening. You don't want to put full air pressure on the water line or you will have more problems. It only takes a few pounds of air to move the water thru to the open valves.

I'm kinda with Azflycaster on this. But - Jeez - please don't let us just do things randomly. If you don't know what you are plugging into, let's don't plug into it.

Give us a chance to help before trouble begins to cost.
