Curious as to what these plugs are.

[djw2112]

I have had this RV since 2016 and i have never noticed these before, looks like they are on my grey tank, any idea what they are?

Also do all tanks have the same, even black?



thanks

Looks like a do-it-yourself job.
Somebody made cleanout holes.

ok thanks, does that typically mean that one is in and other is out?

Looks like someone used pipe plugs to seal leaks.

Can’t answer that but if they are not leaking, leave them alone.

im not touching them, just curious 😀

Yeah, that's the other (and , probably more likely option.)

As close together as they are, I would not presume there is that much logic involved.

Those are call Oops Plugs.

My first thought was, someone installed these to plug a leak. There is no logic to the position, it just happens to be where 2 holes were. If this tank is exposed on the bottom, it's possible a rock hit the tank, or it was driven off road and something hit it, punching holes in the tank. It looks like a quick fix form a Jack-of-all-trades back yard mechanic. If there are no leaks, I agree with others above, .... don't mess with it, ever.

The existence of those plugs is not typical so it is just a guess what they may have been for. Are you the original owner and bought it new? I have see a lot of RV waste tanks and have never seen anything like that. Like others here, I'd bet they were put in by a previous owner and if they go completely through into the tank and you open them, what is inside will come out.

Don’t ever try to open them because sure enough, it could spin loose. In fact I would buy some epoxy cement and keep it inside the rv just in case.
If you have the epoxy, they won’t leak. If you don’t have the epoxy, sure enough they will leak at the worst time.

Oh ok, so that must be different than Oh S _ _t plugs, i guess Oh S _ _ t tank holes are bigger lol

ok i climbed under to get a better look. They are not part of my grey tank, they stick through the underbelly rv insulation and look like some kind of end run for two pex tubes. It has rubber tape around them. Maybe dead ended for some kind of feature.

Then those would probably be your low point drains. One is for the hot side and the other is the cold side

That is exactly what my low point drains look like

the fittings are sealed to keep bugs from getting up in the belly and eventually inside the rv.

 

[djw2112]

ok thanks. What are they used for? Would i ever need to use them for anything?

 

[Rene T]

They are used to drain your system if you need to winterize your rv. How cold does it get where you live?

Not that bad ill probably never have to use them. East Texas 100 miles east of Dallas zone 8. I have never had to use them yet and we have had a few cold winters even down to 11 deg F one season but its rare. I dont winterize anyway because im living in it full time.
