How to Fix RV Washer P-Trap Dry Out and Stop Gray Tank Odors

After not using my RV's gray tank for days, my bathroom is still getting blasted with sewer smells that seem to appear out of nowhere. My 2025 Bay Star 2826 came pre-plumbed for a washer/dryer in the bedroom closet, but we decided not to install one. The problem is that horrible sewer smell keeps coming up through the washer drain pipe - it's making that whole area of the RV unbearable.

I know there's a P-trap down there that's supposed to hold water and block those gray tank odors, but since we're not using the washer connection, that trap just dries out completely. Every few weeks those awful smells come back with a vengeance. I've tried pouring water down there a couple times, which helps temporarily, but it just evaporates again.

Before I start tearing things apart, what's usually the culprit here? And roughly what am I looking at cost-wise for parts? Really hoping this is one of those DIY fixes and not a "call the RV guy" situation. …more

RV Vacuflush Toilet Odor Fix: Stop Black Tank Smells While Driving

After six months on the road, my 2016 Fleetwood Bounder's Vacuflush toilet is eating through air fresheners faster than I can buy them thanks to relentless black tank odors. When parked, no smell at all. What causes this driving-only odor issue and how do I fix it? I'm thinking it's related to air pressure or venting but need to know the exact solution. …more
