Always top notch explanations. Thanks again for the wealth of knowledge you document and share with the rest of us. Cheers!

Hi Guys! This was an EXTREMELY interesting episode! The problem was such a hidden and sneaky culprit but yet right under your nose. As always, love you channel and it's always so informative, entertaining, and professionally done. Happy trails and be safe!

Very good video, and bringing to peoples attention the dynamics of plumbing in a slide out. Another tip on trying to find the source of plumbing odor is to squeeze a couple of drops of peppermint extract down the roof vent (if accessible) and then go inside and sniff for the minty smell.

That is amazing detective work that you guys did. Quite impressive. It is another example of just how poorly designed and constructed so many RVs are, especially with systems located behind the scenes.

Very interesting find. Thank you for posting. Much appreciated. Love and blessings from Ontario Canada!

[jenfugit]

So specific, but fascinating. I love how you guys figured it out and, as always, how you share your information to the RVing world! Thank you!

Fascinating! I can smell my gray water if my gray tank is more than 2/3 full. It’s not a strong smell because the water doesn’t sit long - I usually empty the gray tank every 4 to 5 days. I have a very sensitive sense of smell so it’s possible there is no real problem and this slight odor is normal, but your video helps me understand the plumbing system better so I’m going to check things over. Thank you! 😃

Love your channel, explanations, editing, camera work all top notch! By the way I installed your extra 20 amp outlet plug last year and love having that extra power especially when only 30 amp is available. You guys are great!

I can’t believe a Rv manufacturer would put a sink into a slide. The flexible hose is like a vacuum cleaner hose. Better stock up on your hose supply. Kudos to you for finding the issue!

Outstanding information I am so glad you guys posted this because nobody else could’ve figured it out. You guys are the best. Thomyt

Great video. I’m from Australia and have a motorhome on order. I’m a total rookie, never owned a motorhome or caravan. I haven’t even been camping (in a tent) since the eighties, so I’m thirsty for any info on motorhoming. I love finding out how things work, more so than my husband. It gives you confidence when things break. Like many people, I decided to buy a motorhome when Covid hit and closed the borders. The borders are now reopening but I’m still keen to see my own country. I’m planning on doing the big lap of Australia and mainly free camping.

That’s amazing you found that. I know what to look forward when that happens to us. Thank you for sharing this. You are a gem.

Very funny this video popped up, yesterday we started having that same smell from our gray tank. I had changed the AAV a while ago but seems it has failed. I ordered a new one and hopefully that is the fix. We do not have slides so do not thankfully have to worry about flex pipe, great find!

[howards]

My last rig had the sink in the slide. I had a very similar thing happen. Yes, hard to find for sure.

[larw]

Amazing discovery!!! Thanks for this video.

[joanmcerlean]

Great detective work. Thanks for sharing.

[TomSpurlock]

That was a very interesting story with a good ending. Thanks for sharing.

[raymondschneider]

Interesting video; who'd have guessed (not even THE GEEKS!). Like all of your how-to vids, great video and explanation; talkingk/showing the steps taken are very helpful. Thanks to you both for sharing!

Wow, you never cease to be surprised by issues with housing:). I installed a quarter sized fan that actively vents my grey water tank 24/7, it uses very little power and work well. I tried various Ptraps and they always would drain while on the move.
