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

Fix RV Black Tank Sensors Reading Full When Empty - Easy DIY

This used RV came with black tank sensors that constantly read 2/3 full even after completely dumping and flushing. No matter what I do, the sensors consistently show that misleading reading, and I'm pretty sure this is a sensor probe issue with waste buildup, but I've never cleaned them before and don't want to damage anything. I've heard about using special tank chemicals, sensor cleaning products, and even some kind of ice cube trick, but I need to know the proper methods that actually work.

What are the proven ways to clean RV black tank sensor probes and get my readings back to normal? I really need accurate tank levels so I know when it's actually time to dump! …more

RV Gray Tank Draining Slowly? Fix Clogs & Flow Issues

Called around to shops about my 2019 Forest River Cherokee's gray tank drain crawling—what used to take 5-10 minutes now drags on for 30-45 minutes. The black tank still drains at normal speed, so I don't think it's a problem with the main sewer connection or hose.

I'm wondering what typically causes gray tanks to develop drainage problems over time. We do a lot of dishwashing in the RV and I'm thinking maybe grease or soap buildup could be creating blockages somewhere in the system. The flow starts out okay but quickly reduces to just a trickle, even though I know there's still plenty of water in the tank.

What are the most common culprits behind slow gray tank drainage, and what's the best approach for diagnosing and fixing these flow issues? I'd rather understand the root causes and proper solutions before I start taking things apart or using harsh chemicals that might damage the system. …more

RV Fresh Water Tank Safety: Complete Guide to Preventing Contamination Risks

Between the horror stories about brain-eating amoebas and my complete cluelessness about RV water systems, I'm terrified I'm going to poison myself with my own fresh water tank. I've been RVing for years and never really thought twice about our fresh water tank - we'd fill up wherever, use it for drinking, cooking, even my wife's neti pot rinses.

Now I'm second-guessing everything! How often should I actually be sanitizing our tank? Are there specific water sources I should avoid? And what about activities like nasal irrigation - I keep seeing conflicting advice about what water is actually safe to use. I really want to keep my family safe but also don't want to become completely neurotic about every drop of water we use. What are the real best practices here? …more

How to Sanitize Your RV Water Tank After Summer Storage - Complete Guide to Cleaning and Maintaining Fresh Water Systems

About to tackle sanitizing my Winnebago Navion's water tank this Saturday after months of Arizona summer storage — what supplies should I have ready? The fresh water tank was completely drained before storage and has remained empty for approximately 4 months.

Given the extended storage period and the harsh desert conditions with temperatures exceeding 100°F for most of the summer, I need to determine the proper protocol for bringing the water system back online. Is a simple rinse sufficient, or does this situation warrant a full sanitization procedure?

What is the recommended bleach ratio and contact time for sanitizing after this type of extended hot weather storage? I want to ensure the water system is safe for consumption before our next trip. …more

RV Furnace Won't Ignite But Blower Runs: Complete Troubleshooting Guide

Staring at my 2022 Thor Quantum SE28 furnace after following three YouTube tutorials that somehow made it worse — now it won't ignite despite the blower running perfectly. The unit is getting power and the blower motor kicks on when I call for heat, but I'm not getting any ignition at all - no flame, no heat output. I can hear the blower running strong, so it's definitely getting electrical power, but something in the ignition sequence isn't working.

I've got plenty of propane (3/4 tank) and my stove works fine, so I know gas is flowing to the RV. This is actually the first time I've tried to fire up the furnace this season after it sat unused all summer. The outside vents look clean and I don't see any obvious obstructions, but I'm wondering if there are specific components in the ignition system I should be checking.

What are the most common failure points when you have blower operation but no ignition? I'd like to work through the troubleshooting systematically rather than just throwing parts at it. Are there particular components like switches or igniters that typically cause this symptom? …more
