Winter in Nova Scotia brings harsh conditions that can present unique challenges for RV and camper owners. As temperatures plummet and snow starts to fall, properly maintaining and caring for your holding tanks becomes critical to avoid damage and ensure that your vehicle is ready for the season ahead.

This guide Holding tank 101 we will walk you through the process of cleaning, using, and maintaining your holding tanks during the winter months, with a focus on the specific challenges faced by RV and camper owners in Nova Scotia.


What Are Holding Tanks?

In both RVs and campers, there are typically three types of holding tanks:

  • Freshwater Tank: Stores clean water for drinking, cooking, and cleaning.

  • Gray Water Tank: Holds wastewater from sinks, showers, and washing machines.

  • Black Water Tank: Contains waste from the toilet.


Each of these tanks plays a crucial role in the function of your RV or camper's plumbing system. However, in the cold climates of Nova Scotia, these tanks can become vulnerable to freezing, cracking, and blockages, leading to costly repairs. Proper winter maintenance is key to avoiding these issues and keeping your vehicle functional throughout the season.


Winterizing Your Holding Tank 101

The first step in preparing your RV or camper for winter is winterizing your holding tanks. In Nova Scotia, where temperatures can drop well below freezing, it's essential to take proactive measures to protect your plumbing system.

1. Empty and Flush the Tanks

Before starting the winterizing process, make sure to completely empty the holding tanks. This prevents any remaining water from freezing and potentially causing damage. Here's how to flush and empty each tank:

  • Black Water Tank: Use an RV or camper dump station to dispose of waste from your black water tank. Make sure to handle the waste hose with care and wear gloves.

  • Gray Water Tank: Flush out any remaining wastewater from sinks, showers, and other appliances. After emptying the tanks, it's a good idea to flush them with clean water or a specialized tank cleaner to remove any debris or waste buildup.


2. Add RV Antifreeze

Once the tanks are emptied, it's time to add RV antifreeze. Be sure to use antifreeze designed specifically for RV and camper systems, as it will not harm the environment or plumbing components.

  • Freshwater Tank: Pour antifreeze into the freshwater system through the freshwater inlet. Run water through the faucets, shower, and toilet to ensure the antifreeze reaches all parts of the system.

  • Gray and Black Water Tanks: Add antifreeze to these tanks to prevent any residual waste and water from freezing.

3. Insulate Your Tanks

Given Nova Scotia's harsh winters, insulation is a must. Wrapping your holding tanks with foam insulation will help protect them from freezing. This is particularly important for waste tanks to keep them from freezing in cold temperatures.


Using Your Holding Tanks in Winter

If you plan to continue using your RV or camper during the winter months, you'll need to carefully monitor and manage your holding tanks. Here are some key tips for usage:


1. Monitor Tank Levels

Regularly check the levels of your holding tanks, as you may not have easy access to dump stations in more remote areas. Here's what to look out for:

  • Black Water Tank: Empty it every few days to prevent odors and overflows.

  • Gray Water Tank: Keep an eye on the gray water tank to make sure it doesn’t fill up too quickly. You may want to invest in a tank monitoring system to help track levels, or simply check the tanks manually.


2. Use Tank Treatments

Using tank treatments can help keep your RV or camper's tanks clean and odor-free, especially when they sit for extended periods in cold weather. These treatments break down waste and prevent unpleasant smells.

3. Minimize Water Usage

Conserve water during the winter months to extend the time between dumps and reduce strain on your holding tanks. This will help you avoid frequent stops at dump stations and ensure your system runs efficiently.


Cleaning Your Holding Tanks in Winter

Maintaining clean holding tanks is crucial for both the function and odor control of your system. Here are some helpful tips to keep your tanks in top shape during the colder months:

1. Use Tank Cleaning Tablets

Tank cleaning tablets are an easy and effective way to keep your black and gray water tanks clean. Simply drop a tablet into your toilet or sink, and it will gradually dissolve to help keep your tanks fresh and free of buildup.


2. Perform a Deep Clean at the End of the Season

Before storing your RV or camper for the winter, do a thorough cleaning of your holding tanks. Use an RV-specific tank cleaner and a wand or rinser to clean the tanks thoroughly. This will help prevent waste buildup and ensure the system remains in good working order.

3. Consider a Black Tank Flush System

Many modern RVs and campers come equipped with a black tank flush system, which uses the vehicle's freshwater system to clean the inside of the black water tank. This can help remove stubborn waste buildup and keep your black water tank cleaner for longer.


Preventing Freezing in Cold Weather

Freezing is a major concern for RV and camper owners, especially in climates like Nova Scotia’s. Here are some steps to help prevent freezing and damage to your holding tanks:

1. Insulate Your Tanks

Insulating your holding tanks with foam or fiberglass insulation will help retain heat and prevent freezing. Many RVs and campers also come with heated tank pads, which are an excellent option for keeping tanks warm in freezing temperatures.

2. Use Tank Heaters

If you're planning to use your RV or camper in freezing temperatures, a tank heater is essential. These heaters provide consistent warmth to your holding tanks, ensuring they stay above freezing temperatures even on the coldest nights.

3. Install Winter Covers

Consider installing winter covers on your holding tanks. These covers help protect the tanks from cold air and snow, adding an extra layer of insulation.


Additional Tips for Nova Scotia RV and Camper Owners

  • Know Your Dumping Locations: Access to dump stations may be limited during winter. Before heading out, research the nearest dump stations to ensure you're prepared for waste disposal.

  • Use the Buddy System: If you're planning on winter camping or boondocking, consider traveling with a friend or fellow RV or camper owner. This allows you to share resources like water, waste disposal, and heating systems.

  • Keep Your RV or Camper Warm: Use space heaters or install propane-powered heating systems inside your RV or camper to prevent freezing in your plumbing system. This will help protect your water and waste systems and ensure a comfortable winter experience.


Conclusion

Winterizing and maintaining your RV or camper's holding tanks during Nova Scotia’s cold season is essential for protecting your plumbing system and ensuring a comfortable experience. By following these cleaning, usage, and maintenance tips, you can prevent costly repairs and enjoy your RV or camper all year round, no matter how chilly it gets outside.
