Umarang's Black Water Tank Repairs, Part 2

A couple of days ago, after a test fill, there was still water splashing out of the black water tank's top side.  

It was time to take the tank off to see what was going on.  Dammit.

First though, I removed the toilet to see what could be seen from within the VRRV:

This black fitting secures the toilet to itself and the floor of the VRRV.  Interestingly, its a fitting which is readily available at Home Depot.

At first, I thought a locking ring had broken, which

linked the toilet to the tank.

Took a while and a heated socket before I could remove the four bolts shown above.  The problem then was clear, big cracks atop the tank.  Note the alignment of the tank's hole to the hole in the VRRV's floor.

I believe Jayco, the manufacturers of the RV, didn't drill the hole in the RV floor in quite the right spot, which explains why the fitting's mounting points were all on one side!

So I spent a delightful afternoon removing the tank from the underside of the VRRV.  It required cutting the plumbing at two points (could have done it in one had I given it further thought).

I got the tank out though, minimal cursing and no blood letting aside:

Yep, pretty large cracks. 

I believe the cracks were caused when the tank dropped down earlier this month, since the toilet flange screws onto the large hole atop the tank, it didn't want to release upon the tank's dropping; eventually pulling out when the cracks occurred.  Sigh.

After some cleanup, I used wire mesh and JBWeld Plastiweld/Bonder along with staples to provide mechanical support to seal the cracks.

Below, you can see the toilet flange which attaches to atop the tank from within and secures the toilet as well.  I had it in place to line things up hopefully as the JBweld dried and cured.

The strap was to ensure the toilet flange was straight

up and down as things cured.

There's also Eternabond tape shoring up the underside of the cracks within the tank itself.  I also placed Eternabond tape on the topside as further sealing and reinforcement.  Note: The JBWeld had attached and hardened rather nicely overnight.

Yesterday, Friday November 21

Started the installation of the repaired water tank at mid-morning.  Things went pretty well but some minor issues were encountered.

Once the tank was in place and secured, the toilet flange's threads wouldn't reach the threads in the top of the tank!  Luckily, I found an adapter at Home Depot which extended the reach of the flange enough, though instead of a threaded seal, it was now sealed with Gorilla Glue Sealant.  Should be fine.

I had fortunately picked up appropriate Fernco connectors to rejoin the sections of pipe I had cut to make the removal of the holding tank easier.  The flexibility of such connectors allowed me to reconnect sections with little effort.  The connectors are the rubber tubes with worm gear clamps.

I didn't use ABS cement to seal the black water tank's outlet to the dump gate assembly.  This way, removing it is doable hopefully without damaging things.  Hopefully, I never again have to do it but you never know.

This bit took a while to line up correctly, and I had to remove an unused PVC pipe that was in the way of the dump gate now.  The removed PVC pipe was unused storage for sewer pipe.  You can see the cut off end, on the left side of the pic below.

Once I got things lined up correctly, and straps adjusted, everything seems pretty secure.  

Today, DEC 21

After a quick leak test on the driveway at home, after putting 6 gallons in both gray and black tanks, things looked good.

I then drove the VRRV to Buckley SFB's FamCamp and did further testing for leaks while flushing both tanks.  I had also gotten a water meter from Amazon and determined that I was right, they'd increased the throughput of the water faucet at the dump station!  It recorded a flow of 12 gallons/Minute!  No wonder there'd been water splashing out the top of the tank.

Anyways, things are good to go for now, we'll see how long things last.

Hopefully, there's no part 3 to this subject.

Remounting Umarang's Black Water Tank and Misc.

So there I was last week, trying to drain the black and gray water tanks on Umarang, the VRRV, a couple of cold days and nights after returning home from New Mexico.

The dumping of the tanks' contents seem to go fine.  I then started pushing water in through the dump gate to flush them out and clean them out as usual.

About four minutes into the filling of the black water tank, I heard a loud clunk and water started spewing from the top of the black water tank!  The forward half had come off its mounting bracket, and though the main pipe was held up by the guard I'd installed before, great pressure on the 1.5" ABS pipe from the gray water tank feeding into the dump hub broke the pipe as well.

Yep, water all over the place, luckily "clean-ish" water and not sewage!  

The next day, while back at the RV storage yard, I got the tank back up flush against the bottom of the VRRV.  What a PITA.  I failed to see if there was a seal between the tube from the holding tank and the RV's bottom though.

I believe the forward mounting bracket had lost several of the screws used to hold it and the forward edge of the tank up.  The last one failed while I was filling the tank.  

Note the gap created by the pipe's break.

A bottom up view of the dump hub where the 1.5" pipe from the gray water tank connects.  The tape you see there was an earlier attempt to seal things without actually replacing the pipe.  No such luck.

The dump valve you see is for the black water tank.

As you can see below, there's not much to stop the downward fall of the black water tank, when one of its mount brackets fails.

By Sunday, yesterday, I'd installed two steel straps to support the black water tank in the event it ever comes off the mounts again.  Fingers crossed.

I also, proactively, added a 2x4 board with a 1/8" steel plate brace across the bottom of the gray water tank, to reinforce things.  The factory mount points on the rear edge looked fine and all present.

Gray Water Tank

Dale K., a neighborhood friend and retired Master Plumber came by and made short work of removing the failed pipe, reaming out the stub glued to the dump hub, and installing replacement piping.

He said in his decades of plumbing work, he'd never successfully removed broken off stubs of plastic tubes which were glued together....neither by heat or cutting methods.  

Instead, he used this Socket Saver tool.  Very nice tool indeed and it made short work of the remnants of the tube end which had been connected to the dump hub.

Here's how things looked after the repairs were done:

Looking from rear of RV to front:

Note the steel strapping.  I think it'll be strong enough.

I hope.

You can tell which pipes are the new ones, they're

the clean ones.  :)

This morning, Monday, the pipes in question passed a quick leak test.  I then put about ten gallons of water into the black water tank through the toilet and drove the VRRV to the storage yard at Buckley Space Force Base.

Draining the water at the FamCamp dump facility went well.  No leaks seen from the drive from home.  They must have radically increased the pressure of the water available at the dump station as the black water tank filled up in less than 4 minutes and I saw water gushing from the top of the tank, not, thankfully, from inside the toilet.

I'll admit I'm a bit leery/worried that water gushed out of the top of the black water tank where it mates to the underside of the RV.  Everything seems to be fine in terms of toilet operation, water storage and such but I won't be fully confident till I go through a few fill/dump cycles while camping.  I'm thinking there might have been a seal between the top of holding tank and the RV's underbelly.

I just have to make sure to only fill the black water tank with just a few gallons of water to flush out "remnants" during a dump operation.

I mentioned misc. in the post subject line:  

So, what do the "eyes" above say to you?  Put yourself in the perspective of an approaching camper trying to find a spot to park at .... would the above sight say: Hi, come on over and set up or would it say: Go away?

Update: Nov 18:  did a test fill of the black water tank again and saw water flowing out unexpectedly from the top of tank!  Dammit.  More to follow.

Home for a Bit

Returned from New Mexico after ten fun-filled hours of uneventful driving on the I-25 Super Slab.

After the morning chill had gone, it was pleasingly warm in New Mexico the couple of times I stopped to rest or gas up the VRRV.

This changed soon after I crossed into Colorado, with heavy cloud cover blocking the sun and adding to the overall gloominess and chill on the scenery.  This cloud cover wouldn't break till I got north of Colorado Springs.

It was getting dark as I pulled into my home cul-de-sac, got the trailer with Scarlett still onboard into the garage with no issues and parked the VRRV for the night.

My last view of the campsite as the sun started lighting up the eastern sky:
