Hello, I bought a Raptor 429 to live in full time, it has two bathrooms and the one in the toy hauler garage seems to always smell bad, the other sinks don't, any idea why it might? Picture for flair
Make sure the traps are full of water in all sinks
if it stinks under the sink it might be a bad air admittance valve. If you have one it will be a short piece that sticks up from the drain pipe. The AAV is just screwed on so you can screw it off and replace with a new one from any big box store for about $10.
Sinks would be grey tanks,not black. and they can get smelly too depending on what has been washed away. Shaving, washing greasy/grimey hands ect. What you can try is doing a good rinse, leave about a 1/3rd full and then breaking up a chem pac that’s used in the black tanks and rinse it down your sink. Leave it for a day then flush your grey tank. If it’s a minor issue, this should clear up the smell. If it persists, you may have to have it professionally looked at
Kudos for towing with a flatbed, they work so much better with 5th wheels than a stock body.
Don’t have a clue, but that thing is huge and awesome. Congrats!
Are you sure it’s the sink that smells? Or is it the bathroom in general? Could be the toilet, specifically if it’s a dometic 300..
Man that trailer is way to short. Need to get something longer.
