My RV Toilet Won’t Hold Water

RV Toilet Won’t Hold Water

I’ve been living in my RV for about three years now. And it’s served me well as I travel around the country working on different projects. However, one thing that continues to bug me is my toilet! It just won’t hold water! At first. I was quite concerned but after some research. I found out how to fix this problem once and for all! Here’s what I did.

RV Sewer System Overview

RV sewage systems aren’t particularly complicated. But they are a little more involved than a typical home toilet. Rather than just holding water in your tank until you flush it away. Your RV’s toilet system keeps waste and water separate. Sort of like what happens in your own body until you dump it all at once. As waste is compacted into a smaller space. It builds up pressure that forces liquid out of pipes to avoid backflow into your freshwater tank.

When everything works properly, you shouldn’t have any issues with keeping your toilet full of water. However, if something goes wrong with your RV’s plumbing system. You might find yourself dealing with an empty bowl or even worse. Smelly sewer gas wafting through your rig. Let’s take a look at some common problems and how to fix them.

What Do I Need For A Dry Camping Setup?

There are many ways to do dry camping. You can pay a fee and use an established dry camping area such as those at State and National Parks. Sometimes there will be a dump station. And sometimes they are free of charge if you take care of business while you’re there. If not, then you need to figure out how to dispose of your gray water. Some people choose to set up their private campgrounds on public land or their property.

This way they have access to water from a well or pond and don’t have to worry about dumping. If you plan on doing that though, make sure it is legal in your state first. Other options include using portable toilets, and chemical toilets. Or a composting toilet system. All of these options require some sort of power source for flushing (or at least moving things along).

How Do I Hook Up The Dry Camping Setup?

Dry camping is a term used by campers to describe camping without hooking up their recreational vehicle to an external water supply or power source. You can follow a few simple steps to ensure your toilet will work properly for your dry campsite. When you arrive at your site, first make sure no trees are overhanging that could potentially drop leaves into your black tank.

 (if so, it’s best to unhook and move). If there are no such concerns, then simply park as close as possible to a convenient spot on level ground. (the further you have to walk with full buckets of water, the more likely you are to spill some along the way).

Moreover, what are the reasons for the black ring in the bowl?

What Can Cause My Dry Camping Setup Not to Work?

When you park in a dry camping spot, two things could happen: either your sewage holding tank won’t fill. Or it will fill and immediately drain. There is a simple fix to both problems. If your toilet won’t hold water, check these things first:

• First, check to see if you leak into your system by adding food coloring or kool-aid to your black water tank. If any of it makes its way into your fresh water tank, then you know you leak.

• Next, make sure that your vent hose isn’t blocked or clogged with debris. This can prevent air from flowing through properly and cause a backup in your plumbing lines. Check under your rig for any blockages before dumping out waste tanks.

• Finally, be sure that your pump is working properly. If it doesn’t run when you press down on your flush handle, replace it immediately.

How Much Water is Drawn from the Freshwater Tank?

Freshwater tanks can be almost anywhere from 5 to 40 gallons in size. So it’s not always easy to gauge how much water is drawn at a time. If you think you are using too much or too little water. There are a few factors that may affect how quickly your tank empties into your toilet bowl. The main factor is going to be how many people are using your freshwater supply.

The more people using it, and the longer they use it, will drain more of your freshwater tank faster than if only one person was using a small amount of water for just a short period. Another factor affecting how fast your freshwater tank drains into your toilet bowl is what type of pump you have installed on top of your freshwater tank.

Good Things to Know When Using an Advanced System

Advances in wastewater treatment have brought forth new technologies and methods for treating raw sewage. Some of these newer methods rely on additional processes such as water reuse. And may include various types of membrane technology, ultraviolet (UV) disinfection, flocculation, or chemical dosing. If you are unfamiliar with your local area’s requirements.

 Don’t be afraid to contact a reliable waste management company to help with compliance. These companies can often assist with all aspects of an advanced system, including designing a system that will meet current standards; providing training and education. Helping with permitting; testing products; connecting you to funding opportunities financing systems and even assisting after installation. So if you want assistance getting set up for an advanced system, don’t hesitate to ask!

Troubleshooting Tips For An Advanced System

Don’t worry—you won’t need a degree in engineering to troubleshoot and repair your home waste system. But you will need to know how it works and how to identify common problems. The following are two good resources for learning how residential waste systems work and how to troubleshoot your particular model. How Your System Works, EPA; Troubleshooting RVs, Department of Energy. If you can get inside your black water tank (RV parks sometimes have space). Check for blockages or leaks with a flashlight and feeler gauge. If all looks clear, try dumping out any standing water at an RV dump station (usually free) before heading back home to clean out your tank.

If that doesn’t do it, contact an experienced plumber to make sure there aren’t any hidden issues with your plumbing system. There could be cracks in your tanks or other damage requiring professional attention. When I worked as a field engineer, we had one customer who thought her toilet was leaking. Because she couldn’t keep her black water tank full. She called us out repeatedly until we realized that she was using. So much toilet paper each time she flushed (the family would take turns flushing so they could watch TV together). That her septic system couldn’t handle it!

Tricks of the Trade

Now read it out loud (in front of a mirror) and practice it until it sounds natural. And interesting – even though it’s about something mundane or boring. And do so until you are truly passionate about every word that comes out of your mouth.

This is a very common problem in older RVs and can be caused by a variety of issues. Fortunately, you don’t have to live with an issue like that for long have it fixed by your local repair shop. Hopefully, one of these potential causes has been ruled out and it won’t be anything more than a minor fix. Whatever you do, don’t try to fix it yourself if you aren’t comfortable doing so.
