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 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 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

Newmar Bay Star 3826 Black Tank Vent Pipe Routing: Complete RV Location Guide

This dangerous sewer smell is seeping into my Newmar Bay Star 3826 where my kids are sleeping—could the black tank vent pipe routing be putting my family at risk? I can trace the half bath black tank vent line running through or adjacent to the electrical cabinet area, but I require confirmation of this routing.

The rear bathroom black tank vent pathway is less apparent during my inspection. I need to identify where this vent line routes from the tank connection point up to the roof termination. Understanding both vent pipe locations is critical for proper system maintenance and troubleshooting potential blockage issues. …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 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

Adding Ball Valve to 2008 Fleetwood Terra Heater Line - Safe?

Adding Ball Valve to 2008 Fleetwood Terra Heater Line - Safe?

I turned off my RV's cooling system and grabbed my wrench — ready to install a ball valve on my 2008 Fleetwood Terra's heater line but need safety confirmation first. I've been battling what I suspect is a faulty electric heater valve that may not be closing completely when I switch to A/C mode.

The electric valve is expensive to replace and located in an incredibly awkward spot that's driving me crazy to access. I've tried everything - heat detectors, feeling around the lines, you name it - but I still can't definitively tell if it's actually sealing off hot coolant flow when the A/C is running.

Here's my question: Can I safely install a simple manual ball valve in the heater line before the existing electric valve? I'm hoping this would let me manually shut off coolant flow to the heater core when using A/C, essentially doing the job the electric valve should be doing. Will this cause any problems with the cooling system or damage anything? I just need to know if this is a safe solution before I start cutting into lines. …more
