Dometic 310 Toilet Leaking at Foot Pedal: Complete Fix Guide

Called my weekend camping trip short because my Dometic 310 toilet has water pooling underneath, the flush mechanism sticking, AND that annoying gurgling sound happening constantly. I can see the leak between the fixed outer part and the moving pivot section when the pedal is pressed.

Already replaced the toilet valve but it's still leaking from the same spot. The inlet and outlet hoses look fine. What causes leaks at the pedal mechanism itself after the valve has been changed? …more

How to Fix RV Fresh Water Tank Leaks: Complete Diagnosis & Repair Guide

Nobody warned me how tricky RV fresh water tank leaks could be — got my tools ready and determined to fix this dripping mess under my trailer myself. The dripping was pretty steady at first but seems to have slowed down overnight to just occasional drops. My tank gauge still shows full, so I don't think it's completely emptying out.

I can see there's an underbelly cover that would need to come down to access everything underneath, but I'm hoping maybe there are some easier spots I should check first? I'd rather not tackle removing panels if I don't have to - any guidance on where these leaks typically start would be really helpful, especially near the drain valve! …more

RV Water Pump Pulsing & Cycling Issues: 7 Causes + DIY Solutions

Noticed my RV water pump keeps pulsing and cycling on its own even when no faucets are running - is this dangerous with kids around? The water pump keeps turning on and off rapidly - like every few seconds - even when I don't have any faucets or anything running. It's doing this pulsing thing constantly.

I've heard someone mention something about an accumulator tank, but I'm not really sure what that is or how to check it. Could there be other things causing this too? I'd really appreciate some guidance on what might be wrong and where I should start looking. This is all pretty overwhelming as a beginner! …more

How to Repair RV Roof Soft Spots: Fix Water-Damaged Wood Step-by-Step Guide

My RV roof has had this squishy soft spot right next to the roof vent ever since we got hammered by that nasty rainstorm last month. When I step on that area, it feels spongy and I can tell there's water damage underneath the rubber membrane.

I'm pretty sure water has been leaking through the vent area and rotting the plywood underneath, which seems to be about a hand-sized area. I want to cut the rubber membrane back, replace the damaged wood, and then reseal it properly.

Should I be worried about the structural integrity? What type of materials should I use for the replacement wood, and how do I properly reseal everything to prevent this from happening again? I'm thinking of folding back the rubber, replacing the damaged section of wood, and then resealing the membrane over the new wood. …more
RV Sewer Hose Freezing Temperature & Cold Weather Protection

RV Sewer Hose Freezing Temperature & Cold Weather Protection

Nobody can seem to agree on whether I should winterize my RV sewer hose system now or wait until temperatures actually threaten my specific setup. Current setup involves a dual-hose configuration with approximately 30 feet total length running to septic connection point.

Critical issue: The final two feet of hose rises approximately two inches above the main run elevation before connecting to the septic inlet. This creates a low point where effluent can accumulate rather than draining completely. Overnight temperatures are forecast to drop to 25°F for the next 48 hours.

What is the precise freezing temperature for RV sewer hoses, and does the uphill section with potential standing water create additional freeze risk at this temperature threshold? …more

How to Stop RV Windshield Condensation: Complete Prevention Guide

Between running my AC constantly or relying on fans and ventilation to stop windshield condensation in my 31-foot Class A during Naples' brutal 89% humidity. Experiencing persistent exterior windshield condensation at 5:15 AM, while side windows and rear bedroom window remain clear. Recently modified ventilation by closing all four interior AC roof vents to test temperature regulation effects.

Condensation appears as moderate moisture accumulation on windshield exterior surface, with minimal condensation on some side windows. This occurs during typical Florida morning conditions with significant temperature differential between nighttime glass surface and ambient air humidity levels.

Require systematic approach to eliminate both interior and exterior condensation formation. What are the most effective methods to prevent windshield fogging through humidity control, ventilation management, and thermal barriers?

Coleman Mach AC Leaking Water Inside RV: Complete Troubleshooting Guide to Stop Drips

I'm planning my weekend getaway when I spotted water dripping from my Coleman Mach air conditioner model 49003A879 that definitely wasn't there yesterday. I'm in Myrtle Beach, with super humid conditions (90s with crazy humidity) and getting pea-sized water drops falling from the ceiling vents at maybe 2 drops per minute, which doesn't sound like much but it's making puddles on my floor.

I've been keeping the main ceiling vents mostly closed to push more air to the back of the coach. Climbed up on the roof expecting to find some fancy drain pump or tubing system, but honestly don't see much of anything obvious.

Is this just how these Coleman units work, or am I missing something? Really hoping this isn't a 'deal with it' situation, but wondering if my closed vents are screwing up the airflow or if there's actually a drainage problem I need to fix. …more

RV Water Heater Pressure Relief Valve Leaking: Normal or Problem?

Our brand new 2025 Flagstaff Super lite's Suburban water heater has this annoying steady drip-drip-drip sound coming from the pressure relief valve on the outside. Been living in this thing since August and just noticed it last week.

The thing is, it's not constant - sometimes it's bone dry, other times I'll see a drop or two. We keep the electric heater running pretty much 24/7. My dealer mentioned something about draining and creating an air pocket, but honestly I'm not sure if this is just normal behavior for a new unit or if I've got a legit problem on my hands.

Anyone know if a little PRV dripping is just part of the deal with these water heaters, or should I be looking at a warranty claim here? Don't want to be that guy complaining about nothing, but also don't want to ignore something that could turn into a bigger issue down the road. …more

2021 Ford F53 Chassis Exhaust System: OEM vs Aftermarket Options for Coaches

Staring at my 2021 F53 chassis with the 7.3L V8 after all that rain last week, I'm getting paranoid about my exhaust system condition. Recently, I discovered two exhaust joint leaks on a used coach with only 26k chassis and 9,100 miles - one behind the catalytic converter and another in a bend higher up before the exit point. What's concerning is that water was dripping underneath, which seemed unusual for such a new vehicle. Are these exhaust leaks common, or could they indicate a deeper issue? I want to understand if this is a typical problem or something I should be more worried about before potentially making modifications. …more

1996 Newmar Mountain Aire Diesel Pusher: Complete Owner's Guide & Maintenance Tips

Spent way too much time getting quotes and now I'm staring at $2,800 worth of repairs for my 1996 Newmar Mountain Aire on Ford F530 chassis. Recently, the RV was stored outside and squirrels caused wiring damage, which I've had repaired. Now I'm dealing with a problem where the lights stay on when the transmission goes into reverse. I've already checked the relays and fuses, and been told it might be a faulty reverse sensor, but I can't locate it or find a manual. I need help understanding: 1) What could be causing the reverse lights to stay on (I currently have to remove a relay to turn them off), and 2) Where I might find the reverse sensor on this transmission. Any guidance would be greatly appreciated. …more

How to Fix Shurflo 4008 Pressure Switch Failure: Complete DIY Repair Guide

Every time I turn on a faucet in my new RV, this Shurflo 4008 water pump just won't quit running like it's stuck in overdrive! 🏃‍♂️ Even when I'm not using any water, this thing is chugging away like it's got somewhere important to be.

I'm pretty sure it's the high pressure microswitch acting up. As I learned, this can cause the pump to run continuously due to a high resistance short. The good news is you have multiple repair options:
- Replace just the microswitch
- Replace the pressure housing (3 screws)
- Or swap the entire pump (about $73 on Amazon)

Has anyone dealt with this before? I'd love to avoid replacing the entire pump if possible, but I'm also tired of listening to this mechanical marathon runner! …more

Dana Super 70 Pinion Seal Leaking: When to Worry About RV Differential Seepage

Pulled into camp yesterday and spotted fresh oil weeping around my Dana Super 70 pinion seal - now I'm wondering if this needs immediate attention. Not full-on crying tears of gear oil onto my driveway (thankfully), but definitely looking a bit moist around the edges. Been like this for years now - my RV's apparently got commitment issues with keeping things bone dry.

The plot thickens: even the weld spots where the axle tube meets the diff are joining the sweating party. At 24k miles, I'm wondering if this is just my Dana Super 70 being a drama queen, or if I should be genuinely concerned? No actual drips after sitting all winter in storage, but my OCD brain keeps telling me to grab a flashlight and inspect it daily. Should I be panicking or just accept that my differential has trust issues with seals? …more
