Dometic 310 Toilet Leaking at Foot Pedal: Complete Fix Guide

Called my weekend camping trip short because my Dometic 310 toilet has water pooling underneath, the flush mechanism sticking, AND that annoying gurgling sound happening constantly. I can see the leak between the fixed outer part and the moving pivot section when the pedal is pressed.

Already replaced the toilet valve but it's still leaking from the same spot. The inlet and outlet hoses look fine. What causes leaks at the pedal mechanism itself after the valve has been changed? …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
Fix RV Low Water Pressure on City Connection: Troubleshooting Pump Assembly

Fix RV Low Water Pressure on City Connection: Troubleshooting Pump Assembly

Last week my pressure regulator started reading a solid 40 PSI on city water but my water pump keeps cycling on for 5-6 seconds when everything says it should stay completely off. When I connect to city water, my water pressure regulator shows a solid 40 PSI, which should be plenty, right? But here's the weird part - my water pump keeps kicking on for about 5-6 seconds then shuts off, even though I'm connected to city water and the pump switch is supposed to be off.

The really frustrating thing is that the pressure feels weak throughout the RV, with specifically the bathroom sink and kitchen sink seeming low, though the shower has good pressure. I've already changed out the intake/check valve and don't currently have a filter in the system. I can see the pump running while on city water, which I know is not normal. I noticed the kitchen and bathroom sink screens were plugged - which might explain some pressure issues - but now I'm wondering about the toilet's low pressure. Could there be a screen in the toilet line I'm not seeing?

I've been full-timing for two years and never had this issue before. What should I be checking for? I'm handy enough to do basic repairs but need to know where to focus my troubleshooting efforts. …more
RV Black Tank Flush Not Working - Water Wont Go In

RV Black Tank Flush Not Working - Water Wont Go In

According to my neighbor I need to replace the valve, the RV dealer says it's just a clog, and YouTube insists it's a pump issue with my 2012 36 QSP's black tank flush system. When I connect my hose to the flush port and turn on the water, nothing seems to go into the tank - the water just doesn't flow in like it should.

I'm wondering if there's a check valve that might be stuck or if something is clogged up? I've used the flush connection earlier in the year without any problems, so this is puzzling. I've heard about debris getting in the spray nozzle too. What are the most common causes when the black tank flush won't accept water, and what should I try to fix it? Any guidance would be really appreciated since I'm not sure what to troubleshoot first! …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

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

RV Water Pump Pulsing & Cycling Issues: 7 Causes + DIY Solutions

Noticed my RV water pump keeps pulsing and cycling on its own even when no faucets are running - is this dangerous with kids around? The water pump keeps turning on and off rapidly - like every few seconds - even when I don't have any faucets or anything running. It's doing this pulsing thing constantly.

I've heard someone mention something about an accumulator tank, but I'm not really sure what that is or how to check it. Could there be other things causing this too? I'd really appreciate some guidance on what might be wrong and where I should start looking. This is all pretty overwhelming as a beginner! …more
60 PSI Water Pressure in RV: Is It Too High? (Expert Guide)

60 PSI Water Pressure in RV: Is It Too High? (Expert Guide)

Found myself staring at my water pressure gauge right now and there's 60 PSI showing even though my regulator is preset to 50 PSI. This is the first time I've used this particular gauge (bought it about 6 months ago), and it immediately shot up to 60 with no way to adjust it down.

Is 60 PSI going to damage my RV's plumbing system? I'm worried because that seems high, but I'm not sure if it's actually dangerous or just at the upper limit. Could my regulator be failing, or might this new gauge be giving me a bad reading? I'm planning a trip to get a replacement tomorrow, but I want to make sure I'm addressing the right problem here. …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

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

Dometic 310 Toilet Foot Pedal Problems: When to Replace vs Repair Completely

Since moving into an RV with a Dometic 310 toilet, the foot pedal is acting up in ways I've never encountered before. The foot pedal mechanism has exhibited poor responsiveness, requiring multiple valve replacements over time. Despite these repairs, the pedal continues to malfunction with irregular operation patterns.

Given the recurring nature of this issue and the accumulated maintenance costs, I am evaluating whether to continue with component-level repairs or proceed with a complete toilet replacement. What factors should determine this decision, and at what point does full unit replacement become the more practical solution? …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

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 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
