We perform a black tank flush by bringing in a Valterra A01-0184VP Master Blaster RV Tank Cleaning Wand with Power Nozzle. It will do a nice job of cleaning the toilet and the tank very quickly and efficiently a models where the toilet is directly on top of the black/wastewater tank. All you need is a gentle spray as long as you're using the proper chemicals to keep waste water broken down during toilet use.

Be advised, the black tank flush system has a valve that is located under the sink in the bathroom. These can and do fail. When that happens, water will run wide open into the under sink cabinet and flood your bathroom and everything else. NEVER use the black tank flush without a person inside to monitor that unit. This is on my Keystone Avalanche.

Helpful video except for the recommendation to use RV toilet paper. There are tests that show household "septic safe" toilet paper dissolves faster and it is less expensive.

Thanks very much for posting this video - knowledge is power!

It was a pleasure meeting you 2 recently..thank you for the info!

Well, I’m impressed. Straightforward to the point and quite technical actually. Excellent job!

Fantastic video!!! Thank you so much

This was awesome. Thank you!

Great video with lots of great information

very helpful for first time camper!!

Thank you! Very appreciate!

Great info for newbies such as myself.

Good info as I am a newbie. Thank you both...

One of the best videos I’ve seen Thank you guys

Tanks a lot!!

Thanks for a very helpful video!

Thank YOU

Thank you for this video. Wondered how the tanks were situated and now have a better understanding of how they work. Not too concerned about my sensors not reading correctly, my toilet will 'burp' when it's full.

I purchased a grand design, but I feel like the concept is all the same. Only difference is the living spaces. But I really appreciate the very easy to understand video. It gives me a better understand of how the tanks may be sitting and where they may be. You guys are funny! Keep up the great videos!

Good video thank you :)

Thank you very much!!! Alittle fast for beginners!!! Separate video for each would be helpful and show how to hook up!!!

Thanks god bless

TANKS A LOT!😂

Would love to see a video on how the black tank flush actually work. Is it a mist, a stream of water, or just water running inside the black tank ?

good stuff guys.... seem to have your fresh tank vent & water pump pick up description transposed tho?

Did you guys film this with water tank upside down??? without mentioning???

Great video but I have been trying to find out on the black tank flush what is actually happening in the black tank when you turn the water on and its going into the tank ?Is it spraying all over in the tank or just dumping in the tank. Mine is a factory installed flush on my 2021 freedom express. Any help ? Thank you

Good job. I noticed on my 2022 Bullet 330BHS that when I used the tank flush on the outside by the kitchen slide out I only heard and seen water action in the rear bunkhouse toilet. I went up to the master bath toilet and I didn't hear any water or see any water action in the tank using a flashlight. Shouldn't the black tank flush, flush both tanks? I am a little confused. I also noticed the bunkhouse sink goes into the rear black tank and not the gray tank like the other sinks.

If you’re hooked to fresh water at a campsite. Does the fresh water fill a tank reservoir & then you pull water from that tank ? Or Is it pushing water directly in to the lines. I understand there’s a fresh water tank for boon docking I am wondering how city water works

Would it be better to place the tank heaters on the bottom of the tank?

Is ot true that we should not tow an rv with the fresh water full or half full? Is it made to survive the stress of the road?

I’m having trouble with my galley tank. It keeps backing up in the kitchen and I can’t get it to drain even when I open the galley tank valve. Thanks

can you still use the tank heaters when the tanks are open all the time in the winter

I have a Keystone Carbon 398 with 2 Full Baths. I've notice the trailer has two sets of pull Valves one set up by the Main control center of the trailer, and a second set down by rear drain tube/ outlet. Looking at my Spec. on the trailer it says I have 1 Black tank and 1 Grey tank, so why is there two sets of release valves.

Why are you not using the blue tooth connectivity ? The newest type you can connect to your phone.

I had a salesman tell me that the sensors are no longer just screws wired to the monitor. That they are now sensitive electronics and not to do the old school of dumping ice into the black tank to clean them when traveling (ice sloshing around to clean any build-up). Is this true?

😀Are there any products that can break up black tank solids after years being in storage.

I want to know how to fix it or how it works. When I connected the city water line, my freshwater tank filled up.

I thought this video was going to show how you could remove the black tank after the fact. When it is in between the frame. What has to be done then?

What to do if your drain valve is leaking, is that a esey fix?

Ok, so can i travel with a load of potable water en route to boondock, or travelling in general? What about grey and black out of necessity?

Does Gray water tanks 1 and 2 dump into each other ?

My pump runs but isn't pumping from my fresh water tank, how can you tell if vapor lock, wrong valve directions, or faulty pump, or clogged or kinked air vent?

shared

I assume all tanks are installed in a way that rates them to be 100% full during travel?

2018 Montana 3930 fb Legacy ..... do both toilets go to one black tank or are there two tanks ?

Hold the line of TRUTH!

where can you fill the tanks once they are empty?

I have left my black water open for 2 years,now My toilet is backed up?I have tried so many things.I have left water on it for 1 1/2,what should I do?

What would cause the water pressure to quickly diminish after about 5-10 seconds on a brand new Cougar Half-Ton 30 BHS? Doesn’t seem to be the pump or the supply lines. It seems like either something wrong with the suction line from the fresh water tank like a kink or debris or something in the tank that isn’t allowing for smooth flow. The pump also takes about 30-60 seconds to catch up and shut off after the water has been turned off from the faucet etc.

My shower and bathroom sink are plumbed to the black tank

I'll save you some time. Read chapter 10.

That is NOT Bart Taylor. 😂

Use lots of water

Yea my brand new keystone rv was a waist of money to buy the floor is clapsing dont buy any keystone rv they went down hill in there builds ,my bathroom floor is also sinking .

I have a 2007 Dutchmen Grand Junction 39 ft fifth wheel RV that is going to be permanent on my property I was thinking about removing the tanks or at least the black tank and turning it into a park model but I don't know what kind of job I'm going to have Plumbing it up

this two guys are brothers? they look twins lol

VIN # 4YDTBLM24PT430429 2023 Keystone Bullet Crossfire 2780BH Time line on this camper... I signed papers on this camper on December 9, 2023. I didn't get it home until February 3, 2024. Work Order # 14680W dated 12/5/23 states job 1- Loose trim at bottom of entry door. job 2- Night stand trim needs work (right side). job 3- Master bedroom seam tape and wall panels needs replaced. Cause: Window not sealed causing water damage to unit Correction: Remove window, window valance, blind, trim, sliding door, door track, trim, cabinet, night stand, bed, bed frame, shelf above bed, and put it all back together again and fill all nail holes with color matched wood filler. At the bottom of this work order it states that "The remaining windows on the unit are not sealed properly and going to allow water to intrude in the future." Were ALL these windows even fixed? April 22, 2024... I am in the camper making the beds for our FIRST trip and notice BOTH upper and lower bunks are wet. Upon further inspection the wall panel, the bunk frames, the curtains, and the floor were also wet. There was a 1/4" gap between the wall and the window top. Water was literally dripping from the window frame. I have video of the gap and the water coming in. I had to cancel that trip to get the camper back in for service. Work Order # 15548 dated 4/29/24 job #1- Lower bunk window is leaking. job #2- Upper bunk window is leaking. Cause: window is not properly installed causing a gap in window and not properly sealed. Correction: tighten windows and seal. May 16, 2024 Our first trip... While hooked up to water and the water pump on, we discovered the toilet leaks/spews water from a fitting onto the wall and floor, and the bathroom sink has a pretty substantial drip/leak where it will not shut off. As the day got warmer, we turned on the A/C and discovered there was a gap in the drip rail that allowed condensation/and maybe even rain water, to drip down into the outside speaker. Later that night as we were going to bed, we noticed the night stand trim in the bedroom (that had been "fixed" in w/o # 14680W) was flopping off the wall again. We finish our camping trip inconvenienced by not being able to turn on the water pump. I make an appointment to drop the camper off for yet another "fix". The night before taking this back to Camping World for service, I'm in the camper and notice the lower bunk is wet, again! As I am collecting stuff out of the camper, I notice a hat that had been sitting on the right side night stand in the master bedroom was wet, and a notebook that was on the dinette table was wet. When we go in to drop the camper off, Josh and Bill do a physical walk around and inspection. The wall and nightstand are wet as well. They discover a hole in the right front corner of the roof and tell us all 4 corners of the roof have been patched with some sort of "putty" and this is why the wall and nightstand are wet and is why trim keeps falling off the wall. All of this takes us to Work Order # 15735 dated 5/21/24. job #1- toilet has a massive leak job #2- bathroom faucet will not shut completely off job #3- seam in gutter dripping into outdoor speaker job #4- master bedroom trim is lose again (from W/O #14680W) job #5- lower bunk window is leaking again (from W/O #15548) job #6- dinette window leaks There is no mention of a hole in the roof OR all 4 corners be patched on this work order. No mention of the the wall panels warping. What happens 6 or 10 months from now and the floor and/or walls deteriorate? What happens if mold is discovered? Has anyone even CHECKED BEHIND any of these walls that have been wet? Has anyone checked the stability of the bunk bed frames, where they mount to the wall? Will they deteriorate and come off the wall? The bunk room curtains have been so wet that they have faded and bled black dye onto two set of sheets. What happens when those curtains and the header that they are attached to fall from the wall? We have our annual trip (6 hr drive) coming up. What happens when we find another leak or disastrous situation?? Camping World Customer Service suggested that if we have issues to "reach out to our Elite Tech Support line" and gave me an 844 phone number. The closest Camping World would be AT LEAST 147 miles away! And how would I contact them with no cell service or internet in the hills and back woods of Missouri?? We are not "glampers"...we do off grid or "boon-docking". This camper is not as solid or dependable as it should be for a NEW camper. As of todays date, I have made 7 payments on this camper. It has 96 miles on it...30 to a campground, and 66 miles to Camping World for service. I spoke to Nicole at Keystone Customer Service about a Swap Out or Buy Back. I would swap for another Keystone Bullet. We have always had good luck with Keystone campers and have thought of them as a quality camper. However, this particular camper has some serious issues. Issues that I'm not sure can be corrected properly.
