Boat owners often face the problem of foul odours emanating from their heads. This is usually due to the build-up of waste in the holding tank, which can be mitigated by regularly pumping out the tank. However, this alone may not be sufficient to eliminate the odour, and additional steps may be necessary. One solution is to use a deodorizer or treatment product, such as SEALAND’s Toilet Treatment, which can be poured into the head and flushed. Another option is to use a hose and tank cleaner, such as Raritan C.H. Hose & Tank Cleaner, to remove any deposits from the hoses and walls of the tank. In some cases, the problem may lie with the plumbing, and it may be necessary to replace the hoses or valves in the system. For example, the joker valve, which prevents backflow from the holding tank, may be corroded or leaking, causing odours to escape. It is also important to ensure that the vent hose is not clogged or located too close to the boat's interior, as this can cause odours to waft into the boat. While there are various methods to address boat head odours, prevention is key, and regular maintenance, such as flushing the head with fresh water and treating the holding tank, can help keep smells at bay.

What You'll Learn
Check the hoses for permeation
Checking the hoses for permeation is an important step in maintaining your boat's sanitation system and preventing foul odours. Hoses are considered "flexible" connections, so if a hose is rigid and brittle, it may be time for a replacement. Hoses with a date code older than seven years should also be replaced.
To check for permeation, wrap the hoses in aluminium foil and seal for a week. Then, insert a hydrogen sulfide detector under the foil and take a reading. Alternatively, perform a sniff test by running a damp cloth along the hoses and smelling it for any odours. If the cloth smells bad, the hose is permeated and needs to be replaced.
When choosing a replacement hose, it is important to match the hose to its specific application. For sanitation use, the best hoses are thick-walled, smooth on the inside, and made of reinforced PVC. These hoses should be clearly marked and have low permeability to prevent smells and other problems.
To prevent odours, hoses should be installed with no sags or loops to prevent standing water, which can cause premature ageing and permeation. It is also important to regularly pump out the boat, especially in warmer climates, and treat the holding tank with an odour treatment like SEALAND's Toilet Treatment.

Clean the joker valve
Cleaning the joker valve on your boat can be an unpleasant but necessary task. The joker valve is a rubber valve that lets waste out of the toilet and into the holding tank, but not the other way around. If your joker valve is leaking or deteriorating, it can cause an odour on your boat. Here is a step-by-step guide to cleaning the joker valve:
- Gather your supplies: You will need gloves, a Phillips-head screwdriver, a pan or rags, and a replacement joker valve. It is recommended to replace the joker valve annually as a preventative measure.
- Locate the joker valve: The joker valve is usually found at the base of the toilet.
- Remove the discharge elbow: Take off the three Phillips-head screws that hold the discharge elbow in place. Once removed, the joker valve will be exposed.
- Inspect the joker valve: Check if the joker valve is coated in calcium buildup or other debris. If there is significant buildup, it may be time to replace the valve.
- Remove the old joker valve: Take out the old joker valve and inspect the inside perimeter of the discharge elbow to ensure it is clear of any waste or debris.
- Install the new joker valve: Insert the new joker valve, making sure it is facing the correct way. The triangle-shaped structure should be pointing inwards.
- Reinstall the discharge elbow: Put the discharge elbow back in place, ensuring it is correctly aligned. When screwing it in, be careful not to overtighten the screws, as this can crack the plastic.
- Test the toilet: Once the new joker valve is installed, test the toilet by flushing it and checking for any leaks.
By following these steps, you can effectively clean and maintain the joker valve on your boat's toilet, helping to prevent odours and maintain proper functioning.

Clean the flapper valve
Cleaning the flapper valve on your boat head can be a smelly and arduous task, but it is necessary to maintain a fresh-smelling boat. The flapper valve is part of a dual-action piston pump head and can be a root cause of a stinky boat head.
To clean the flapper valve, first, you will need to remove the flapper by unscrewing it. Then, clean the area underneath the seal. You can use a damp cloth to clean this area, and be sure to check for any deposit buildup. If you find any deposits, be sure to remove them. You can use a flat-head screwdriver to remove any buildup. Once the area is clean, you can replace the flapper valve.
While you have the head disassembled, it is a good idea to take a look at the inlet valve and give it a cleaning as well. The inlet valve can also contribute to odours, so it is important to ensure it is clean and functioning properly.
If you find that the flapper valve is leaking or deteriorating, it may need to be replaced. You can find replacement flapper valves at marine supply stores or online. Be sure to get the correct size and type of flapper valve for your specific boat head.
In some cases, you may need to remove the entire head to access the flapper valve. This can be a more complicated process, and you may need to consult a boat head specialist for assistance. However, if you are comfortable with basic plumbing and mechanical tasks, you may be able to remove the head yourself.
Remember to follow the three golden rules of boat head maintenance: regularly pump out your boat, treat your boat's holding tank, and keep the hoses connected to the head clean and odour-free. By following these rules and keeping your flapper valve clean and well-maintained, you can help prevent unpleasant odours on your boat.

Flush with fresh water
Flushing with fresh water is a crucial step in maintaining your boat's head and preventing odours. Here are some detailed instructions and tips to help you effectively flush with fresh water:
Understand the Benefits of Fresh Water
Salt water is a common cause of odours in boat heads due to the presence of microscopic organisms that decay in the holding tank. Using fresh water for flushing can significantly reduce these odours and improve your boat's sanitation system.
Pump Out the Holding Tank
Before flushing with fresh water, ensure that you have pumped out the holding tank. This is an essential step to remove waste and prevent odours from building up. You can do this by visiting a pump-out station or calling a pump-out boat service.
Treat the Holding Tank
After pumping out the tank, it is recommended to treat it with an odour control product. Look for products specifically designed for marine heads, such as SEALAND's Toilet Treatment. Empty the recommended amount of the product into the head and flush the toilet. This will help prevent odours from forming in the hoses and lines of the sanitation system.
Repeat the Process Regularly
Flushing with fresh water and treating the holding tank should be done on a regular basis, especially in warmer climates. The frequency may vary depending on your boat's usage, but aim to do this at least once a month or as needed.
Combine with Other Maintenance Practices
Flushing with fresh water is just one aspect of proper boat head maintenance. Combine it with other practices such as cleaning the bowl, hoses, and tank with fresh water; replacing hoses and valves as needed; and using deodorizing or enzyme-based products in the tank. These combined efforts will help keep your boat's head odour-free.
Remember to always follow local regulations and environmentally friendly practices when dealing with boat sanitation. Proper maintenance and regular flushing with fresh water will go a long way towards keeping your boat's head in good condition and free from unpleasant smells.

Use a deodorising product
There are many products available to help deodorise your boat head. However, it's important to be wary of what you put into your head, as some products can shorten the life of the joker valve, the essential valve that prevents backflow from the holding tank.
Tank Deodorisers
Tank deodorisers are available in a variety of colours and can be purchased from Walmart or marine suppliers. These can be poured directly into the tank, but be aware that some contain formaldehyde, which can compound the problem downstream. If you're looking for a more environmentally friendly option, try an enzyme-based product.
Borax
Borax is an old-world, Yankee solution for deodorising your boat head. Dissolve a cup of borax in a quart of hot water, then add three more quarts of water. This solution can be poured directly into your tank.
Vinegar
Vinegar is a cheap and effective cleaner that can be used to deodorise your boat head. It's also useful for removing salt deposits and freshening the water. Simply pour some vinegar into your tank and flush.
Bleach
While bleach can be effective at deodorising, it can also be hard on equipment. If you do use bleach, be sure to dilute it with water first. Never use bleach if your tank contains ammonia, as this can create a toxic gas.
Water Softener
Using a water softener can help prevent waste from sticking to the sides of your tank. Simply add two cups of water softener to your tank through the system.
Tank Additives
There are several holding tank additives available that are effective at controlling odours. These products can be added directly to your tank and will help control odours at the source.
