The Drip of a Dismal Dometic 320
It’s a crisp morning at the campsite, coffee brewing, and your Dometic 320 toilet—the porcelain throne of your RV—should be a reliable pitstop. But when water pools around its base, that gravity-flush, 18-inch-high unit betrays you, soaking the floor and souring your adventure. This RV staple—loved for its home-like flush and sturdy build—shouldn’t leak like a cheap hose. Worn seal? Loose valve? Cracked base? A dripping toilet isn’t just a mess—it’s a trip ruiner needing a fix. Let’s plug this Dometic 320 in 20 minutes and keep your campground vibes dry—no more soggy setbacks.
Digging Into the Leak Lament
Grab a flashlight and play RV plumber—flush the toilet, watch the flow. Water at base—seal failing; steady drip? Valve loose—pedal sticks or wobbles? Bowl leaks—cracks in ceramic?
Hose loose—check inlet; wet or slack? Tank full—overpressure? Debris in flush—grit jamming seal? Each splash’s a clue—trace the trickle on your Dometic 320.
Fixing the Drip Disaster (20 Minutes)
Seal it dry—turn off water (valve, $0, 1 min). Seal worn? Replace (Dometic 320 gasket, $15, 8 min)—unscrew bowl (wrench, $10), swap gasket, reassemble. Valve loose? Tighten screws (screwdriver, $5, 3 min)—check pedal spring.
Hose slack? Secure clamp (pliers, $5, 2 min). Debris stuck? Clean flush valve (brush, $2, 3 min)—flush twice. Test—turn water on, flush 5x, 3 min; dry floor’s your gold; leaks stay? Pro for cracks ($100+). In 20 minutes, your toilet’s tight—you’re the campground champ.
Preventing Leak Letdowns
Keep it dry—check seals yearly; rubber wears fast. Flush clean—avoid wipes, they clog. Tighten valves—vibrations loosen screws. And winterize—freezing cracks porcelain. Your Dometic 320 should now stay leak-free. For more RV fixes, explore our RV & Camping Fixes guides.
