(:HowTo:) Permanently Fix a Leak/Crack in an RV Black or Grey Water Holding Tank ~#3 Dropping a Tank

[@arminius301]

great fix but it's a hell of a lot of work to end up with an already compromised tank. I'd recommend replacing the tank with stainless steel and never having to worry about it cracking, but I appreciate the attention to detail, thanks for posting.

[@DeltaTwoNovember]

A bozillion videos on how to clean or fill an RV tank - first one I've seen where somebody actually drops the tank. Thanks for making this video. I get the privilege of dropping all my tanks (pre-existing poor floor repair that needs remediation), and this moves me in the right direction.

[@kennethcapps2223]

Thanks Man, I didn't take my time a few years ago. I actually took the tank out and just plumbed my toilet to go to a valve and then straight to the septic. Think I want to try to fix that black tank so I can go Boondocking again, lol!!!

[@viewsandreviews180]

Thank you for sharing this method of repair. I have one thing to suggest; there are rubber couplings with band clamps that could be used to secure the pipe ends together just in case the tank get hit by something that causes it to leak again.

[@stevejohnsonm.a.7557]

Great step-by-step instructional video. You just saved me a bundle by showing me how to do it myself. Thanks!

[@brianphillippe1694]

very awesome video! Thanks a million TrailerDayz. I will be using your method on My Son's Tank since I ruined his. Was going to use fiber glass cloth. NOT now.

[@randallbitner9359]

Great Video. Wish I saw these before using tape and other goop. My crack is on the 3 inch exit pipe. About 6 inches long so too long for a strap repair. Going to try your methods as another option. Thanks Great Vids. Repair people are not looking for music, introductions or welcome messages, we will remember you without all that time consuming stuff. Thanks. Following now.

[@JBA749]

I am in the middle of doing my mother in law's motor home. I had to cut the closet flange off to drop her tank and the vent pipe in two places. Thank you for the video.

[@1eustaquiod]

My hat is off to you cause you were patient enough to explain every step well hope you continue to do more videos.

[@Afrikaislife]

Thank you for saying "I cleaned the surface very WELL."

[@mikedoingmikethings702]

The more I see stuff breaking on TT abs tank breaking makes me want to upgrade all my tank into SS steel. Thank you for sharing...

[@wild_horses]

Just buy a portable dump tank and get rid of the on board black tank.

[@NativeSon60]

I would plastic weld it with a hot iron. We use plastic welders in body shops quite often. A soldering iron will do the job.

[@sirzoso2005]

Dude, you saved me hundreds of dollars!!! Great video and that ABS putty is the %*+×!!! Thanks for the information!!!

[@jmcastro1]

thank you so very much, I've been looking on how to replace or repair my tank. Your the best!

[@BarryDorfman]

Great video! Thanks for showing the details of getting the tank out. You said you were using a union to put the pipes back together. In fact, you used just a simple coupler. It would be best to use a real union so that you can easily take it apart for the next time you have to remove the tank.

Can’t find the video of you showing how to make the Pec"s Flush Wand. Great video, by the way.

[@edsadventures2422]

Looking for new tank. Abs cement ate right through. . .

[@Tongan_Steve.McGarrett]

Great job! Happy to find this video to help me with my repairs. I'm curious though....how did you put the bottom covering/underlayment back?

[@TrailerDayz]

It just screws back on. Pretty straightforward

[@VitiatedsHOWTO]

I need the links to those videos

[@fourzerofour7860]

Thanks! Very informative and useful. Sadly I may be having to replace my black tank soon, and this has been very valuable to see what I'll be getting a into.

[@newcince]

What kind of screen do you use?

[@RedStickBull]

Thanks for the video. I'll need it because I'm new to RVing and my Tub wouldn't drain, I thought it was stopped up but all it was - gray water tank was full and need to be emptied. I didn't know this and I used my air compressor to unstop the drain and this caused a leak in the piping where it attaches to the top of the gray water tank,

[@williamwarren4442]

Did not explain steps could not follow , what I saw looked good but ?

[@KevinCoop1]

Very nice video! Hope I never have to do this. Any reason you can't weld the tank? I welded some abs for a different use, but it is still solid. Respectfully, Kevin

[@TrailerDayz]

You can totally weld a crack. Even better, weld the crack and then weld a large patch of Abs over it.

[@gcorpus5558]

Could you use flex seal in the crack?

[@TheHavocdog]

It looks like the Crack was progressing away from the vent. That tells me that the tank was moving in relation to the vent pipe. Probably during travel. The Crack will re develop with time if you don't intervene. I would put a flexible connection between the tank and the vent pipe.

[@littleleatries]

Yes, one of the BEST video I have ever seen! wow!!!!!!!!!!!

[@sailingsolar]

Do you do this for a living? How is it you have done so many tank repairs. cheers.

[@RandyK1ng]

Great vid. When beefing up the inlet/outlet areas, would it be a good idea to screen around and up those pipes as well, or is that a waste?

[@TrailerDayz]

Wouldn't hurt if it's a weak point on the tank

[@anonymous_friend]

What is the spray can you used at the end? I missed that.

[@brandonreprogle947]

Hey man can’t find the video of you showing how make one of those hose attachments to spray out the tank.

[@TrailerDayz]

Wow. Looks like I never uploaded it. I'll have to find it.

[@anayelimagali3717]

While cleaning my Black tank I got distracted and eventually overfield the Black and it busted. The rip is on top, so for now we just have to leave the black open. Is there any way to fix the rip or do you have to buy a new one.

[@donanderson2792]

How long After the patch before you test it. Can you use it while finishing the repair..doing a double application

[@TrailerDayz]

24 hours is best. I wouldn't use it during the repair.

[@steveokel3257]

Do I need to know what material the tank is or is all the plastic the same? 2014 trailer. Also, mine is the black tank, do I need to remove the toilet or be concerned about that connection?

[@TrailerDayz]

If it's black, then it's ABS.

[@TrailerDayz]

If you are removing the tank, yes, all connections need to be cut or disconnected.

[@atlaseca]

i have a leak some where when i have the city water on where would the leak be? my rooms carpet gets soak also

[@alexisjennings1818]

Can this method be used where the tank is spin welded for the drain pipes? I think that’s where my leak is coming from

[@TrailerDayz]

No. A white tank is made of a different material (polyurethane) those need to be repaired with spin weld plugs.

[@alexisjennings1818]

@@TrailerDayz the tank isn’t white. It’s black like in the video. I can get to it through the access panel. It’s kind of the same as video #2. I don’t know what you mean by white tank

[@TrailerDayz]

@@alexisjennings1818 A white tank is usually for fresh water and will be square. A black tank will be for Grey or black water and will have rounded edges. All black tanks will be made of ABS plastic and these methods will work.

[@dsmith3239]

Wow! Love the quality and precise cutting of the hole in the floor for the drain pipe to the tank. Looks like someone thought it was a 10 inch drain pipe rather than the normal 1 1/2 pipe. Typical crappy RV factory construction.

[@thesarcasticangrydud]

Hi great video. I'm glad I did some research before just buying a new tank, for an old trailer. This last year I hit a bit of a dip and ripped off the entire discharge pipe for the grey and black water off right off.... yes we were off road... and it was more of a mud hole. lol. However, after watching your videos I am fairly confident I can fix it. Problem is I have to replace the flange on the black water. You had mentioned you did a vid, showing how to do this, but I can't seem to find it. Would you be able to send the link? or maybe let me know what part I will need to install a new flange onto the tank. Thank you, and cheers in advance.

[@TrailerDayz]

You mean the blade valve, or the actual output flange the you glue the exit pipe into?

[@thesarcasticangrydud]

@@TrailerDayz well both to be honest... the entire discharge pipe was ripped off. Blade valve, right to the tank. And the flange on the tank is mangled. So I will need to replace the entire discharge pipe. Blade valves included. It's all at the bottom of a mud hole in the mountains somewhere up the Coquihalla highway near Merrit. I figured the blade valves would be easy enough to order off Amazon. I am guessing a large ball valve wouldn't work that well for Blackwater?

[@TrailerDayz]

@@thesarcasticangrydud Yep. Blade valves are cheap. You can replace just the valve: amzn.to/2IIU1LZ Or the whole thing with inlet flanges. Not sure if you can easily get the drain flange. If you have anything left of an outlet pipe at all it might be best to glue onto it with an ABS union.

[@thesarcasticangrydud]

@@TrailerDayz there is a little bit of flange left at the tank, but it's pretty mangled, and it's cracked around the bottom, and the crack carries on up the side of the tank. If you have an email address, I can send you a quick video. Your advice would be greatly appreciated. The tank is easily accessible.

[@ronaldmcclung1706]

@@TrailerDayz Thank you, young fella. Likes your video "guide" & your decent grammer. First time hearing "blade" valve. Folk also incorrectly call them "slide valve". The correct name is gate valve. "Ball valves" are correctly called globe valves. Where is that video of making your swizzle stick?

[@kennethsouthard6042]

Given that you had already fixed it once and those things seem to sell for around a hundred bucks or so, why not replace it?

[@ronaldmcclung1706]

You answered your question in the asking: $100.

[@margaretpaine7292]

Where are your gloves, a tarp and hair comb? I need to remove my sewage tank but I'm not replacing it. I just want to Mouse proof my trailer. Nice repair though. Looks rough reinstalling but you did good. Oh yes and overalls. You need some.

[@TrailerDayz]

I'll try to remember to comb my hair and wear overalls in the next video.

[@pauldailey4477]

Nice job. However, when you say the crack´s "natural state" I thought of the tank mounted and half full of waste water. I guess that would be diffucult to simulate and it probably was not necessary.

[@Pabkojdim]

I have a black tank that's been sprayed with foam to protect it from cold weather but it now has a leak and the spray foams been saturated with human matter. What would be the easiest way to remove the spray foam safely without the human matters dripping on me?

[@TrailerDayz]

Xue Lee Your gonna have to let it dry then go in with a putty knife and just start scraping it off. Once you get down to the ABS, you will need to sand off the foam residue.

[@Pabkojdim]

@@TrailerDayz Alright thanks. here goes it.

[@jeromehendrix2991]

Really really great video. Only thing is I don't t know how to get to the tank itself. Every guide show it being done on a trailer but I am having this problem on a rv. Can you show how to get to the tank?

[@TrailerDayz]

Is it a class A or class C?

[@jeromehendrix2991]

It's a class a. 1997 National tropical 235 widebody

[@TrailerDayz]

@@jeromehendrix2991 Your tanks are probably going to be behind panels in you lower storage compartments. You're gonna have to start unscrewing panels to find them.

[@jeromehendrix2991]

@@TrailerDayz lol. My worst fear is I have to drop the gas tank and cut through the wood because there are no panels

[@dewill9725]

what is the mixture for the stuff in the jar?

[@rickyvillanueva7309]

Why not use fiberglass

[@TrailerDayz]

Fiberglass won't make a covalent bond with the ABS. It will leak.

[@MrErichonda30]

Tank has no support underneath from the factory. Which is probably why it cracked in the first place.

[@TrailerDayz]

Honestly, they normally break at the seams, or where the ports are glued on..

[@freetolook3727]

Blair Trailer Project.

[@TrailerDayz]

LOL. It felt that way sometimes.

[@ckstaff]

keep in mind, this method only works for abs tanks, not polyethylene. Make sure you determine what kind your tank is. There is a much better way to fix these tanks, both abs and polyethylene, and actually makes the tank better and stronger than original, especially abs and there is no awful messy fiberglass and resin to deal with and no glues necessary. This method is incredibly slow, a lot of work and add up the cost of all the materials. Whew, to much time and work and only bridging the cracks. It will seal but wont gain any strength, no matter how many coats are put on.

[@jrm163]

What’s your method please?

[@faithfulnavigatorraul8048]

dear Mr. trailerdays. nice job showing your repairs but a suggestion on your improvements for you and followers to believe job really satisfy the repair is to be tested before to install when is removed or when job is done your video must looks like complete and more believe it

[@VitiatedsHOWTO]

I got some gorilla glue caulk that will fix that crack real quick

[@JoseMoreno-kn7wg]

Just silicone it.
