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

Ford E450 V10 Reliability: Expected Mileage and Longevity Guide for RV Owners

Nobody prepared me for staring at this 2018 Jayco Greyhawk 29MVP with Ford E450 chassis showing 54,000 miles and wondering if I'm looking at a money pit. The unit appears well-maintained with quality features including auto-leveling, fiberglass roof and nose, plus J-ride suspension. However, the odometer shows 54,000 miles, which exceeds my initial target range.

I need to assess whether this mileage represents significant wear on the E450/V10 drivetrain combination. What is the typical service life expectation for these engines when properly maintained? At what point should mileage become a primary concern versus overall mechanical condition? …more

RV Water Pump Running But No Water? Complete Troubleshooting Guide 202

Finally looking at my RV water pump right now and it's running constantly but there's absolutely zero water coming out of any faucets. However, when activating any fixture throughout the system, the water pump initiates and runs continuously without producing water flow at any outlet point.

All system components appear to be functioning mechanically - pump motor engages properly, electrical connections are secure, and there are no visible leaks in accessible plumbing runs. The symptom manifests uniformly across all water delivery points including kitchen, bathroom, and exterior service connections.

What diagnostic steps should be performed to identify the root cause of this no-flow condition despite continuous pump operation? …more

How to Fix RV Slideout Rubbing Against Exterior Wall - Complete Repair Guide

Finally figured out why my neighbor's slideout glides like butter while mine scrapes horribly against the exterior wall every time — what's their secret? My slideout has started rubbing against the exterior bathroom wall, and the coach is perfectly level.

The main thing I've noticed is that the gap at the bottom of the slide is much smaller now compared to the top - it used to be about 1½-2 inches at the bottom, but now it's barely anything. There's also about a ½ inch difference in height from one end of the slide to the other when I measure from the top.

I've independently jacked up both sides of the slide more than an inch each and checked the gap, but neither showed a difference. When I crawled underneath, I couldn't see where the slide might have moved laterally closer to the wall. The exterior stripes still line up. I also noticed the shower hasn't been used in 6 years or longer (I bought this coach used).

I'm wondering if this could be some kind of drooping issue? I've heard about things like rollers wearing out, but I honestly don't know what to look for or where to start troubleshooting. Should I be checking underneath the RV? Any advice on what might be causing this rubbing and smaller gap would be hugely appreciated! …more
How to Fix Stuck RV Toilet Valve After Winterization - Step by Step

How to Fix Stuck RV Toilet Valve After Winterization - Step by Step

Called a repair shop about my RV toilet valve that only gets stuck when it's above 60 degrees outside — works perfectly fine during colder weather after winterization. During the camping season, my toilet works perfectly fine - the dump valve opens and closes smoothly without any problems. However, after I winterize my RV for winter storage and drain all the water from the system, I consistently run into the same frustrating problem when I try to de-winterize in spring.

The toilet dump valve gets completely stuck in the closed position and requires significant force to get it moving again. It seems like the valve mechanism seizes up during the months of storage when there's no water in the system. I'm assuming this happens because the seals and moving parts dry out completely without any moisture present during winter storage.

What's the best preventive maintenance I can do to keep this valve from sticking during winterization? Are there specific lubricants or treatments I should apply to the valve mechanism and seals before putting the RV into storage? I'd rather prevent this problem from happening in the first place rather than having to force a stuck valve every spring and risk damaging the toilet. …more

How to Winterize RV Dishwasher and Washing Machine with Antifreeze - Complete Guide

During my first walkthrough of this RV I bought last month, I discovered the previous owner never properly winterized the dishwasher and washing machine. I've got a Fisher & Paykel dishwasher and a Contoure front loading washer that I absolutely cannot let freeze up.

I know I need to use RV antifreeze, but I'm honestly confused about the exact process. Do I just pour it in and run a cycle? How much do I use? I've read horror stories about people using the wrong type of antifreeze and ruining everything. I really need someone to walk me through the correct steps before I mess this up! …more

Dead House Batteries on 50 Amp Shore Power: Troubleshooting Guide

Turned on my 2024 Entegra Reatta XL this morning to find the house batteries completely dead again despite being plugged into 50 amp shore power—third time this season and I'm done guessing. New batteries, good connections, power was working fine for days then died completely. Voltmeter shows 12.69V on chassis, 4.7V on house batteries at the BIM.

What's the proper troubleshooting sequence for house batteries not charging on shore power? Need to check converter, breakers, and connections but want to do this systematically. …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
Plumbing Medium 30 min 85 👍

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 Water Heater Popping Noise: Causes & How to Fix

I found myself replacing the heating element, flushing the tank, checking every connection — but my RV water heater still makes these loud popping and crackling noises whenever it's heating up. It's got me a bit worried since I'm not sure what's normal and what isn't with these systems.

Is this something I should be concerned about? Could it be dangerous or cause damage if I don't address it? I've heard people mention draining water heaters but I'm not really sure when that's necessary or how to tell if that's what mine needs. Any guidance would be really appreciated! …more

How to Winterize RV Residential Fridge Water Filter: Remove vs Bypass

Before winterizing, my RV's residential fridge started making bizarre gurgling sounds from the water filter area that I've never heard before. I had my motorhome winterized professionally, but when I checked afterwards, I noticed they left the water filter in place instead of removing it or installing a bypass plug.

Is this the correct procedure, or should the filter have been removed? I'm worried about potential damage from antifreeze or freezing, but I don't want to second-guess the professionals if this is normal. What's the proper way to handle the water filter during winterization? …more

How to Travel with a Winterized RV: Complete Cold Weather Guide

I noticed my travel trailer isn't winterized for my Connecticut to Florida Keys trip in February — can't afford professional service right now, need DIY solutions under $200? I'll be stopping at my brother's place in New Jersey first, and then caravaning to our first stop in Fredericksburg, VA at a KOA with a full bathhouse.

I've winterized my travel trailer for the cold months up here, and I recently heard a podcast about travelers staying winterized and using RV antifreeze for quick bathroom needs during the trip. I'm wondering if anyone has experience with this approach.

I know I could de-winterize before leaving, but I'm worried about pipes freezing during the drive south since we'll be going through some cold states. On the other hand, traveling winterized means no water systems working during the trip. What's the smartest way to handle this? Should I keep it winterized for the whole drive and deal with no water, or is there a better strategy I'm missing? …more

1997 Ford Rexhall Overheating: Complete Repair Guide & Troubleshooting Steps

Nobody told me my 1997 Ford Rexhall Class A would keep overheating like this, and now I'm terrified of engine damage. I've already flushed the radiator multiple times and added fresh coolant, but the overheating problem persists.

I'm hesitant to start taking things apart without knowing what I'm looking for, and I'm concerned about making the problem worse. What are the most likely culprits I should check next? I've heard it could be the thermostat or water pump, but I want to make sure I'm checking everything systematically before spending money on parts that might not fix the issue. …more

Motoraid Heat Exchanger Maintenance Guide: RV Engine Coolant Heating System Care

Our Motoraid heat exchanger is showing 180°F on the gauge but everything I've read says our 2008 Ford V10 RV should be running closer to 200°F. Currently experiencing an antifreeze leak around my Atwood GCH10A-4E hot water tank. The leak is draining my antifreeze reservoir quickly, costing me $53 per 3L refill (already on my third jug). I'm wondering if there's a safe way to temporarily bypass the engine heat assist system without risking engine damage until I can get professional repair. What temporary solutions or diagnostic steps would you recommend? …more
