RV LEAK! (Fresh Water Tank RV Leak Fix)

well we just finished up with filming RV unplugged and first time Bo knucking for a long time and we got a leak and so we've been to co pull out our entire underbelly was full of water so I don't know if it's our fresh tank or what that was leaking but I had to drill a couple of holes in the uh in the membrane here to leak all the water out and uh I drilled a couple of holes in there about three four minutes ago and it's still that steady stream of water coming out so it was [Music] [Music] full I started checking uh behind the the Nautilus system I checked all the lines there all the lines going into the kitchen all the lines going to the bathroom and all the lines behind the washer and I didn't see any water anywhere so somewhere from maybe the connection where the fresh water goes to under the island or goes to the fresh tank uh may have had a leak when I was filling it we have a leak somewhere I'm probably going to have to drop this skirting and uh take a look in there I do have one of the fiber optic cameras so either I will run it up through one of these holes that I already drilled and see if what I can see in there or I will take this uh skirting off just a little bit and uh see if I can get a look in there if I can't get a good look without taking the whole thing off then I will try to use the fiber optic camera to go in there but we have a leak somewhere and uh I mean you can see the whole time I've been talking this is still leaking out so it was probably leaking the entire time we were out there boondocking and shooting RV unplugged so all right here's what I got going on now a squeaky door going on apparently I need some WD40 on that but um pulled the underbelly down a little bit and looked in there and I can see there was lots of water drained it all out by drilling the holes in there and since we've been hooked up to City Water we haven't leaked so it has to do with something from the Fresh tank to the water pump it's either where the water's picking up from the tank to the pump or somewhere along the way or where the freshwater connection from the tank goes to the pump I look behind the Nautilus system and the pump is not leaking so that's not an issue freshwater tank now I just put about 20 gallons in there and I'm going to take a look in there to see if it is actively leaking without the pump on I'm not sure how well you can see in there but there's no active dripping I can't see anything actively dripping but you can you can see where the water line is and it where it runs downhill and pulls up and there's a little bit of water that's pulled up right here I'll just pull this skirting down and let that drain out but back there is where the fresh tank connects to the pecs unfortunately it's on the other side I'm going to have to take the skirting down on that side to get a better look at that over there now there's some places that I just can't see can't get into it's too tight and so what I've done is I got this industrial endoscope which basically has a screen has a cord with a camera so I can run this up into places that I can't reach and the end is lit has a camera on it so I'll be able to see on the screen problem is it when it twists and turns it like flips upside down but it can run along the side of the pipes and I can at least see where fittings and fixtures are where I can't get into cuz there's there's a area where the pipe from from the Fresh tank goes all the way up to the Nautilus system there's no obvious leaks behind the Nautilus system and I'm going to turn on the pump and see if I can see dripping in there if I can see dripping in there I can use this to get closer to it to see what I need to see here's what I'm talking about this is what I can see and you see this core it's pretty long so I got lots of lots of space and at the end is this uh camera with a light on the end of it and as I'm move this around I'll be able to see what's going on inside the uh the bay there I'll just run this down into like crevices and alongside pipes and hopefully I'll be able to see where the leaks coming from you might feel a little pressure this has been really cool we've used it several times and I was able to see a lot of the lines in there I couldn't show it on camera CU it was just too much to try to run that and show it on camera but this thing is really cool we got on Amazon I'll leave a link in the descript description so it's really cool for you know pipes wires stuff that you can't see can't get to well I couldn't see anything with just the tank got some water in it pump off doesn't appear to be leaking so I'm going to do is I'm going to turn it to dry camping mode because of a drip pattern it's all been pulling up down here and I was able to see on the other side when I pulled the skirting off I was able to see the connection where the pecs connect into the fresh tank and it's not leaking from there and it's dry up the hill up here so it's leaking from somewhere down here and so the only thing that I can deduce is that it's coming from somewhere up there because you can see one of the lines comes from the freshwater tank side and runs up there and there is some insulation up there I don't see any dripping right now but I'm thinking that maybe that you got to wait until that insulation gets saturated before it's dripping down here I I can pretty much isolate it though I because the the puddles are are right down in this area right here and so and then it ran down that way and and pulled up down there but there's no there's no lines down there there's no water lines down in this area so that's just where the water was sitting that's not where it originated from and because it's dry up the hill up that way it has to be in this area right here so it almost has to be coming from up in there I just don't know how to get to it well I think I got it I came back out and this puddle right here that I had drained was back full and you can see there's a line there's a line of water coming from over there running all the way over here and back and filling this puddle back up so it's coming it's originating from over there where the PEX plugs into the fresh tank I didn't see it when I looked over there earlier but now I can see the water line running down so it definitely is coming from over there and so I'm going to go back over on that side and see if I can get a closer look from that side I think I found it show the origin of it I can see where it's dripping off the fresh tank we got to find out the origin of it there's this little part that's plugged up with like some tar looking stuff and I think it's coming out of there right there is the culprit that is the problem right there I think it's where one of the sensors it's plugged in cuz you can see some wires and it was running down there and then dripping off the tank right there where you see that little blob of tar and to the right of it you can see where the water's been running down and it caused a little bit of a stain there and uh yeah so I got to put some sealant around there and see if that works it's going to keep leaking as long as there's water in the fresh tank so I need to drain the fresh tank make sure that once I drain the fresh tank that the leak is stopped because there's no water in there to leak and I guess it only leaks if your fresh tank is over a certain level because when I had only 20 gallons in there it wasn't leaking um it's first time we've had this leak and we filled up our tanks completely forb unplugged so that's why U and I just it wasn't leaking at 20 gallons I put 20 more gallons in so at 40 gallons it is leaking so I'm going to empty it dry up that area where it's dripping make sure there's no other leak coming in there there I'll put some sealant around that area there wait about 24 hours and then I'll fill the fresh tank back up and see if it's still leaking tomorrow I got it mostly buttoned back up now I um did leave that one little opening open I didn't seal it up yet I'm waiting on Alliance to get back to me let me know what type of sealant to use I only want to do this one time well I fig figured out what to use for sealing up the fresh tank but I'm not going to do it today because the place that we're at we're only here for a couple days but you can see it is just dirt and I don't want to be laying down in the dirt and I think the next place we're going to it might be dirt too but I don't know I'll take the risk cuz this it rained last night and I'd be having to lay down in this dirt trying to get up under there to fix this tank and uh I just really don't want to do it the place that we're at right now is actually our home is our home that's like on our driver's license this is escapees Park in Bush nail Florida and so this is our address but we've never been here before it's crazy because we've been on the road for about two years now using this address and we've never been home so this this is home and I'll show you something that happened to us yesterday which was really unfortunate this has never happened to us before but I guess as we were driving down the road a piece of trash and I think it was an ice bag stuck to the tailpipe of the truck wrapped around it and then melted and I don't know how to get that off so if you know how to get this off I ripped off all that I could rip off there's some underneath there that I ripped off um but for the most part that stuff is really melted on there and I don't know how to get off so if you know how to get it off leave us a comment and as soon as we get to the next location I'm going to fix the fresh tank and I'll show you exactly what we're going to use to do it with all right it's time to fix this fresh tank and Alliance told us what we need to use is this this this is JB Weld plastic bonder they suggested black but the only thing I could find at Walmart is the tan color so it's going to look like I'm smearing baby all over the tank but cosmetically it's not a big deal it's under the back of the RV up under that belly so you're never going to see it anyway so we got that I have some alcohol I'm going to use that with my rag to clean off the area and then I have to have a little bowl cuz when you take this syringe and squirt it in the bowl I give you a little uh popsicle stick in there you're supposed to Stir It Up and then you put it on the affected area which I'll do I won't be able to film that because it's really tight up in there I can barely get my hands up in there so but I will you've already seen them before and then once I get the JB Weld on there I will show you what it looks like while it's wet and then about 24 hours from now even though it says it um it bonds or it sets in 15 minutes and you can sand it in 30 minutes so it's dry enough to sand it down so half hour it should be good but I'm going to let it go for 24 hours anyway but I'll show you what it looks like with it in there wet and then tomorrow around this time I'll show you what it looks like after it's all dried up then we'll put some water in it tomorrow and test it and see if it's fixed well it is an absolute mess in there just because I had to use my hand to get that stuff up in there and then and I got a handful of JB Weld and it's hitting wires and cords and stuff on the way in there knocking a little bit out of my hand it's it's running down my hand because I have to go up like that to get in there first before I turn it and then try to smear it around that seam and as I'm smearing it's just dripping everywhere so it is a hot mess in there hopefully I hit around that seal enough to to get it good cuz I only got one tube of JB W and I just used it so if I didn't get it good enough um we'll try it again tomorrow but hopefully I I did all right let's check the old JB Weld oh that's a mess up there let me feel it though let's see what it feels like oh yeah that is solid I think that's going to work all right we got the JB Weld on there and uh now we just got got to fill the freshwater tank we'll fill it past that sensor make sure it's not leaking so that it's going to take a little while to get past that 2/3 full all right let's get back up under here we got the Overflow coming right there that means the tank is full and so now I'm going to look up in here and check on our JB Weld and see if it's leaking inside there or not well I'm basically an rvtech I find a problem I run it down I fix it it's what I [Laughter] do look that's exactly what happened I figured out there was a problem I ran it down well and iix I figured out there was a problem and water was pouring out of the bottom of our RV so you're basically a tech also anyway um happy to report that the JB Weld held yes and the leak is stopped yep and we can now put fresh water in our tank without having to worry about filling up the underbelly full of water winning and we still have the two drill holes there just in case right just in case but there was nothing down there to damage so nothing really got hurt and we had time to see work on it and it wasn't leaking hooked up City water which is great so um worked out pretty good mhm and the JB Weld only was like eight bucks yeah $8 fix man sweet I like cheap fixes better than calling a tech out for hundreds of dollars yeah and then they're going to go oh man yeah your whole sensor's messed up which is normally what we would have done yeah the threads on your thing where it plugs in Jack we're going to have to replace the whole tank it's going to be about 8900 bucks and we would have gone okay all right I prefer the 8 JB Weld exactly works out good yes that stuff holds good man yeah yeah and you ain't getting it back off no wherever you put it that's where it's at yeah be precise yeah which I wouldn't of course not I've seen your ceiling I can barely get my hand in there so it was like you know I had and it was blind so you get your hand in there you can't have your you can't look and you can do one or the other so I had to get a handful and like reach up there and slather it on hope I'm hitting the right spots and he dripping all over the place and luckily it's all hidden by the underbelly than Bo cuz you'd be like unlike your sealant job is not hidden why bringing up old stuff because it's still a problem anyway the problem's fixed we'll talk about my sealent off camera hey stick around for a few seconds we're gonna honor Fallen Hero you want to get involved with helping us help veterans while we're out on the road everything you need to know is right down in the description of the video appreciate you watching need an rvtech give me a call don't we'll see you next time [Music] bye [Music]
