How to Repair a Hole in RV Grey Water Tank

How to Repair a Hole in RV Grey Water Tank

Tried marine epoxy on my old Class A's tank and it worked perfectly — but now I've drilled a 1 inch hole in my ABS grey water tank while running battery cables. The hole is in an awkward spot near the rear wheel vault with thick metal bars and beams, making repairs challenging.

What's the best way to repair this? I've prepared a patch by flattening and heat forming a pipe section, beveling edges and scouring surfaces for a strong mechanical bond. Should I cement the ABS patch and then cover with fiberglass, or are there other recommended repair methods? I want to ensure a durable fix for this tricky tank damage. …more

RV Grey Water Tank Clogged? 7 Proven Solutions to Clear Blockages Fast

Found out my RV service tech wants $800+ to replace the entire grey water system on my 2007 RV for an intermittent blockage that seems fixable. It doesn't seem to matter if we're level or not - it's completely random.

I've tried using a high suction shop vac and even attempted snaking it, but I'm nervous about forcing things and making the problem worse. I suspect it might be a manufacturing plug that fell into the tank, but I'm not sure. I found one solution with a reverse flush valve that seems to work temporarily, but I'm concerned about the underlying cause.

What are the safest and most proven methods to diagnose and fix these random grey water blockages? I don't want to damage the tank or create bigger problems, but this unpredictable draining is driving me crazy. Are there specific cleaning products or techniques that actually work without risking harm to the system? …more

RV Black Tank Not Holding Full Capacity: 7 Common Causes and DIY Repair Solutions

Somewhere between embarrassed and desperate, I have to ask this probably dumb question: why does my RV's black tank act full when it should hold way more? We have a 40-gallon black tank, but when I try to fill it with water for cleaning, it starts overflowing through the vent pipe at only 23 gallons. I'm afraid there might be something seriously wrong with the installation or that I could damage the system.

A professional cleaning service said the tank was completely clean with no blockages, so I'm confused about why it won't hold its full capacity. The water is definitely coming out the vent pipe, so I assume that means the vent isn't blocked? I'm hesitant to keep trying things without understanding what's actually causing this - could this be a safety issue or sign of improper installation? What should I be looking for to diagnose this safely? …more

Ford E450 Inertia Switch Location Guide - Find Your RV's Fuel Cutoff Reset Point

Every Ford E450 I've worked on had the inertia switch behind the driver's panel — but my 2011 Freedom Elite 32r has it hidden somewhere completely different. The engine is experiencing what appears to be fuel delivery issues after a minor fender bender, and I suspect the inertia switch may have been triggered and needs to be reset.

I've already done extensive searching in the typical locations - removed both driver and passenger side kick panels completely, pulled out the glove box, and even partially disassembled sections of the dashboard. Despite checking all these common spots where Ford usually places these switches, I'm coming up empty-handed.

Could the switch be integrated into another component on this particular year and model? Are there any alternative locations specific to the E450 chassis or Freedom Elite configuration that I should be checking? I'm also wondering if some models of this year might not have a traditional standalone inertia switch at all. …more

RV Tank Sensor Removal Guide: Gray & Black Water Tank Sensors (Step-by-Step Process)

Somewhere between throwing $150 at new RV tank sensors and just ripping out these faulty gray and black water sensors completely, I'm wondering which route makes more sense? Was looking at changing my gray/black water tank sensors, but when I crawled under there, this is what I found. What kind of sensors are these and how do you remove them? I'd really appreciate some specific advice about the sensor type and removal technique. …more

Tiffin Phaeton Atwood Levelegs Won't Fill Airbags: Troubleshooting Guide

Around 85°F, my 2008 Tiffin Phaeton with Atwood Levelegs refuses to fill the airbags for leveling — works perfectly in cooler weather. The coach is sitting low and I can't get it to fill the airbags properly. One of my leveling jacks isn't working right now.

Are the Levelegs and air suspension connected systems? What should I check to get my coach to raise up so I can drive safely? Is this something I can troubleshoot myself or do I need professional help? …more

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

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.

There has to be a better long-term solution than me crawling under there with a pitcher of water every month, right? What do other RVers do when they have an unused washer hookup that keeps letting sewer gases escape? …more

How to Fix Parasitic Battery Drain in 2006 Damon Challenger RV: Complete Troubleshooting Guide

I found three different "experts" telling me three different causes for my 2006 Damon Challenger's parasitic battery drain - neighbor blames the converter, dealer says bad fuse, YouTube points to inverter. I've traced it to the instrument cluster fuse, and Thor doesn't have schematics for this model due to its age.

I'm not even sure if it's actually the instrument cluster itself or something connected to it - could it be the transmission temp sensor, engine temp sensor, or other wiring? I really don't want to damage anything expensive or create a safety hazard. What's the safest way to diagnose and fix this without causing more problems? I'd feel much better with a step-by-step approach that won't leave me stranded or worse. …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 Toilet Paper: Do You Really Need Special Paper for Your RV?

Apparently I'm getting charged premium prices for special RV toilet paper for my 2025 Entegra Anthem and wondering if it's actually necessary with a macerator pump system. The RV has both macerator dump pump and macerator toilet components. I typically dump every 2-3 days at RV parks, with occasional dry camping extending to 5-day intervals before dumping.

Given the mechanical grinding action of the macerator system, I'm questioning whether RV-specific toilet paper is actually necessary. Regular household toilet paper costs significantly less than RV-branded products. My concern is potential damage to the macerator mechanism or holding tank complications.

I also want to understand if using a black tank treatment packet every few days is beneficial, and whether four toilet flushes with water is sufficient for tank maintenance. What are the technical requirements for toilet paper compatibility with macerator pump systems? Are there specific regular toilet paper brands that perform adequately, or should I continue purchasing RV-specific products for system reliability? …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

Thor Ace Macerator vs Gravity Dump: Complete RV Waste System Setup Guide

Woke up to my neighbor insisting I ditch the macerator on my 2013 Thor Ace 29.2, my dealer pushing me to keep it, and YouTube saying something completely different. How exactly does this work? Like, do I need to do something to switch between them on the passenger and driver sides, or can I just use whichever one I want whenever?

I'm assuming there's gotta be some kind of valve system to control which outlet gets the flow? Just want to make sure I don't mess something up by having both open at the same time or whatever. …more

Fix Newmar Water Tank Overflow at 20% - Complete Guide

Fix Newmar Water Tank Overflow at 20% - Complete Guide

I got the fresh water tank filled on our 2018 Newmar New Aire yesterday but something still doesn't seem right — it overflowed through the vent at only 20% on the gauge. Every time I try to fill the fresh water tank, it starts overflowing through the overflow vent when the tank gauge shows only 20% full. This seems dangerous and wasteful - we can't get enough water for our family of four. I'm really concerned there might be a serious problem with the tank or plumbing system that could affect our safety on the road. Has anyone experienced this issue before? I need to know if this is something I can fix myself or if I should cancel our trip and head to a repair shop immediately. …more
