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 Roof Leak Around Air Conditioner: Complete Repair Guide

Around noon Saturday I'm planning to tackle this stubborn RV roof leak by my air conditioner — what tools should I gather beforehand? My rooftop air conditioner is letting water in every time it rains, and when I climbed up there (probably looking like a graceful gazelle), I can see the sealant around the AC unit is definitely cracked and peeling.

I'm standing in the RV section of the hardware store looking at about 47 different tubes of sealant, and I have no idea which one won't turn into another cracked mess in six months. What's the best product to properly reseal around an RV air conditioner? I'd rather not repeat this whole 'indoor rain shower' experience again! …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

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
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

RV Gray Tank Draining Slowly? Fix Clogs & Flow Issues

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

Why RV Water Smells Bad After Storage: Quick Fix Guide

Pulled the RV out of winter storage and the water smells like rotten eggs the second I turn on any faucet. Hot and cold both reek. Sanitized the tank with bleach before storage but clearly something went wrong over the winter. Need this fixed before our first trip next weekend. …more

Thetford Aria Deluxe 2 Toilet Blade Assembly Installation: Step-by-Step Guide

Finally picked up my RV last month only to discover the previous owner left the Thetford Aria Deluxe 2 toilet blade assembly completely botched and leaking everywhere. The replacement kit included multiple washers of different sizes, but the installation documentation lacks clear specifications for proper washer positioning.

I need to verify the correct placement sequence for the rubber washers - specifically which washer interfaces with the bowl surface and how the smaller washers should be positioned relative to the mounting hardware. The leak appears to be originating from the assembly-to-bowl junction, suggesting improper seal alignment during reassembly. …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
