RV Water Pump Losing Prime: Troubleshooting & Winterization

Got a 2022 Tiffin Open Road 34PA with a water pump that keeps losing prime during winterization — about to buy a replacement but wondering if I'm throwing money at the wrong problem? I can get it back by quickly opening and closing one of the lowest drain valves, but then it just loses prime again after a while. This has happened on other RVs I've winterized too, but it's particularly stubborn on this Tiffin.

I'm suspecting it might be the inline check valve next to the pump or maybe the one behind the Truma hot water heater, but I'd love some guidance on proper diagnosis. What are the most common causes of prime loss during winterization, and what's the best way to troubleshoot and fix this? I want to make sure I'm covering all my bases for winter storage prep. …more

Atwood GC10A-4E Replacement: Best Tankless RV Heaters

Halfway through draining my Atwood GC10A-4E's supposed 10-gallon capacity, the water's already running cold but my gauge shows I've only pulled maybe 6 gallons. Are there any dual-fuel tankless units that would work as a replacement? I know there's no plug-and-play option, but what are the best tankless water heaters that offer both gas and electric operation for RVs? …more

RV Propane Regulator Freezing Up? Common Causes & Easy Fixes

About the third time this season my propane system is acting up during cold weather prep and I'm done trying to figure this out on my own. When temperatures drop, I notice my propane regulator develops frost on it and the gas flow seems to slow down or stop completely. This makes me nervous - is this actually normal behavior or do I have a serious problem?

I'm worried about running my furnace and other propane appliances when this happens. Should I be concerned about safety? And if this freezing is normal, what's the safest way to prevent it from happening? I don't want to do anything that might make the situation worse or create a hazardous condition. …more

RV LP Gas Detector False Alarms: Complete Troubleshooting Guide

Already tried everything but my RV's LP gas detector has false alarms in the garage, keeps beeping at random times, AND won't reset properly. Even with the LP tank completely shut off, the alarm still goes off within hours. It's located in the bottom of the fridge cabinet.

I've checked everywhere for actual leaks - can't smell anything, and all my appliances still light immediately when I take the RV out. The detector seems fine outside but becomes a nightmare indoors. I'm wondering if it's the sensor going bad, poor placement, or if there are other things that can trigger these detectors besides actual propane leaks?

I really need a complete breakdown of what causes these false alarms and how to fix this issue once and for all. Should I be looking at replacing the detector entirely, or are there troubleshooting steps I'm missing? …more

RV Water Heater Not Hot Enough: Fix Lukewarm Water Issues

RV Water Heater Not Hot Enough: Fix Lukewarm Water Issues

Looked forward to our two-week cross-country trip starting tomorrow until I discovered my RV water heater that used to produce scalding hot water now barely gets lukewarm. Both the electric and gas functions appear to be working - I can hear the gas igniting and see the electric indicator light - but the water temperature just won't get hot enough for a decent shower.

I've been dealing with this for weeks now and it's driving me crazy. The water gets warm, but nowhere near the hot temperatures I used to get. Is this a common problem with RV water heaters? What are the most likely culprits when you're getting lukewarm water instead of hot? I really need to figure out what's causing this and how to fix it before my next camping trip. …more

RV Water Heater Pilot Light Won't Stay Lit: Thermocouple Troubleshooting Guide

Three different RV shops quoted me $400+ to fix my Suburban water heater's pilot light that won't stay lit and I'm wondering if I can tackle this thermocouple issue myself. the pilot lights up just fine, but the second I let go of that button it dies. I can hold it down for like a minute and think I've got it, but nope - releases and it's gone.

I'm wondering if this is one of those thermocouple things I keep hearing about? Like, is that the little sensor thingy that's supposed to keep the gas flowing when there's a flame? Pretty sure that's what's acting up but want to make sure before I start messing with it. …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 Connect Your RV Solar System to Power Your House: Complete Wiring Guide

Between midnight and 6 AM, my 2001 Ford E450's Victron 3000W solar system keeps flipping itself from RV to house power mode completely on its own. The bus is parked in my driveway and currently running a mini split efficiently with minimal power draw from the battery bank.

My house has a secondary electrical panel with a 30-amp inlet that I normally use for my Honda generator, connected through a transfer switch. The panel feeds 2x 20-amp and 4x 15-amp circuits. Since the solar system is producing excess power while parked, I want to utilize this capacity to power my house circuits.

What's the proper method to connect the Victron inverter output to my existing 30-amp house inlet? I need to understand the safe connection procedure, power limitations of the 3000W system, and any critical monitoring requirements for the battery bank when supplying house loads instead of just the RV systems. …more

Onan Code 36 Fix: Complete Troubleshooting Guide for RV Owners

Got my tools spread out and I'm determined to fix this Onan QP 3600 LP generator (Model 3.6KY-26120R) that's throwing code 36 myself — where's the best place to start? The unit starts immediately but shuts down right away. I have plenty of propane and the oil level is fine.

Water Heater Hot When Empty - No Safety Protection Issue

Finally asking what's probably a dumb question, but why is my RV water heater getting scorching hot even when it's completely empty? After 10+ years of RV ownership, I somehow managed to leave my water heater running while empty and connected to shore power. When I opened the access panel today, that sucker was HOT.

I'm honestly amazed I haven't burned anything down yet - or at least fried the heating element. I always assumed there was some kind of built-in safety feature that would shut things down if the tank went dry, but apparently my water heater didn't get that memo.

So here's my slightly embarrassing question: Do most RV water heaters actually have dry-fire protection, or am I supposed to rely on my apparently non-existent common sense? And more importantly, what can I do to prevent my future self from making this same bone-headed mistake again? …more

RV Sewer Hose Freezing Temperature & Cold Weather Protection
Plumbing Medium 30 min 207 👍

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

60 PSI Water Pressure in RV: Is It Too High? (Expert Guide)

Found myself staring at my water pressure gauge right now and there's 60 PSI showing even though my regulator is preset to 50 PSI. This is the first time I've used this particular gauge (bought it about 6 months ago), and it immediately shot up to 60 with no way to adjust it down.

Is 60 PSI going to damage my RV's plumbing system? I'm worried because that seems high, but I'm not sure if it's actually dangerous or just at the upper limit. Could my regulator be failing, or might this new gauge be giving me a bad reading? I'm planning a trip to get a replacement tomorrow, but I want to make sure I'm addressing the right problem here. …more
