The article discusses the controversy surrounding aluminium holding tanks, with some arguing that they should be avoided entirely due to potential issues such as pitting and weld failure. Thickwalled polyethylene is the recommended material for holding tanks, while rotomolded tanks are the most common. Ronco Plastics offers waste holding tank kits, RV-style sewer kits, and pipe-to-hose adapter kits.
Although small marine holding tanks meet legal requirements, larger tanks offer greater time between pump outs, but not all boats can accommodate them. Waste holding tanks include fitting relocation kits, RV-style sewer kits, holding tank vent filters, and pipe-to-hose adapter kits. The main concern is corrosion, which can be addressed by using distilled water and possibly an annode in the tank. 5083 marine-grade aluminum is ideal for applications requiring superlative corrosion resistance in hostile environments. Sealed pipe fittings and plugs offer easy conversion from waste storage to water storage on most tanks at Defender.
The average life of an aluminum water tank is about 20 years due to the cumulative effect of carrying chlorinated water. To address this issue, the “cleanest” and most economical method is to fit a cassette and seal up the old tank. Threaded female fittings to accept male hose connectors are electronically welded to holes cut in the tank wall. Some companies also make up custom tanks with epoxy barrier coating.
The article concludes by discussing the importance of selecting the right grade for aluminum fuel tanks for boats, with some considering 5052 as the best grade. Overall, the article provides a comprehensive guide to the different types of aluminum tanks and their potential issues.

How to seal an aluminum water tank?
To repair a leak in a tank, use a 320grit sandpaper to scuff the area where the JB Weld will adhere. Mix the JB Weld according to the instructions, apply it thinly to the leak area, allowing 2mm overlap around the pin hole. Allow the putty to set up and harden fully. Inspect the repair for bubbles or cavities, sometimes requiring a second application. Use a sharpened wooden stir stick to tease out air bubbles. Once the putty has fully set, put fluid back in the tank and let it sit for 2-3 hours to check if the leak has been repaired.
What are boat holding tanks made of?
The holding tank is a crucial part of a boat’s waste management and plumbing system, collecting and storing wastewater and solids. It requires regular pumping and cleaning to prevent the build-up of odors, germs, and unsanitary conditions. To choose the right size for your boat, consider factors such as the maximum number of people on board, the space available for mounting it in the boat’s bilge, storage capacity, material compatibility with waste types, installation proximity to the toilet, odor control, vent line, pumping frequency, tank monitor, and off-season storage.
There are hundreds of sizes available for holding tanks, and selecting the right size depends on factors like the number of people on board, the duration of the voyage, and the availability of space for mounting it in the boat’s bilge. The tank’s size also determines its storage capacity, which depends on factors like pumping service frequency and daily sewage flow.
The tank’s material plays a vital role in its functioning, and choosing materials compatible with the type of waste being stored helps prevent unintended interactions between the tank material and waste products. Installing the tank close to the toilet is essential, but gravity discharge is only possible if the tank is installed above the waterline.
Odor control is another important aspect to consider, and using bio-active treatments like Raritan’s K. O. Kills Odors can help maintain an odor-free system. The vent line should allow fresh air to exchange for carbon dioxide generated by sewage, and a short, straight, and horizontal vent line is recommended.
Maintaining the holding tank is essential to avoid sludge build-up in the fittings and walls. Raritan’s C. H. Clean Hoses is a non-toxic, biodegradable, non-hazardous, and safe option for cleaning the hoses leading to the holding tank.
In conclusion, choosing the right holding tank for your boat is a long-term investment that requires careful consideration and maintenance.
What is the purpose of a holding tank?
Holding tanks are large containers used for collecting and storing wastewater and solids. They serve as temporary housing until they are pumped out for treatment and disposal. Regular use accumulates waste within the tank, requiring pumping and cleaning to prevent unsanitary conditions. Service Pumping and Drain Co., Inc.™ provides commercial-grade non-hazardous wastewater holding tanks and pumping for existing tanks. They can meet customer storage and maintenance requirements with quality products and services.
Unlike septic tanks, holding tanks are not attached to a drain field, and everything inside accumulates until emptied by pumping. Pumping frequency depends on tank size and usage, but should occur every few weeks or every month. Aboveground tanks are preferred due to easier identification and repair of leaks.

What is inside a welding tank?
Acetylene cylinders are a type of cylinder that contain acetylene gas dissolved in acetone, absorbed into a calcium silicate porous mass to prevent decomposition. They should be stored upright to prevent leaks. Cyl-Tec’s acetylene cylinders are fully inspected and leak-tested before delivery, with capacities ranging from 10 CF (MC) to 420 CF, and are asbestos-free. They are filled with high-quality glass fiber-reinforced, calcium silicate porous mass and manufactured to DOT-8AL/TC-8WAM specifications.
How long will holding tank last?
Holding tanks require pumping every 6-8 weeks, unlike septic tank pumping which is recommended every 2 to 3 years. This is because holding tanks temporarily store waste for removal and transportation to a treatment facility. The frequency of holding tank pumping depends on factors such as the number of people using water on the property, the number of toilets, showerheads, washing machines, faucets, the frequency of home use, and the frequency of guests and parties. Therefore, there is no universally recommended frequency for holding tank pumping.
What were the three different holding tanks for the water?
RV holding tanks consist of three parts: a black tank for toilet wastewater, a gray tank for sink and shower wastewater, and a freshwater tank for clean water. The black tank is crucial for collecting and storing toilet wastewater, containing human waste, toilet paper, and other waste products. Regular emptying of the tank prevents backups and odors, and prevents it from becoming clogged and causing damage to the RV. Overflow can also cause health issues for the people riding the vehicle. Proper maintenance of the RV sewage system is essential for a comfortable, safe, and efficient camping experience.
What is the difference between a septic tank and a holding tank?
Holding tanks and septic tanks are two types of wastewater treatment systems. Holding tanks store raw wastewater until a pumper removes it, while septic tanks provide primary treatment by separating it into three layers. Holding tanks are typically used by houses without a municipal sewer connection or in unsuitable conditions for an on-site septic system. They may also be used during new constructions before a permanent sewage system is installed.
Septic tanks are used by houses and cottages without a municipal sewer connection and with suitable space and soil for an on-site septic system. According to Statistics Canada, at least 15 Canadian households use septic tank systems to treat their wastewater.
Is aluminum tank safe for drinking water?
Chlorine, a commonly utilized chemical, has the potential to corrode aluminum, resulting in the release of aluminum oxide and the formation of a white powder. The corrosive effect of chlorine on aluminum renders drinking water unsuitable for consumption, given the potential health risks associated with its ingestion.
What is the best material for a boat water tank?

The flexible nature of the material also allows for easy removal and storage when not in use, ensuring efficient space management on board.
📹 Aluminum Fuel Tank Repair? “Could this be true”
The video follows a person who is trying to repair a corroded aluminum fuel tank on their boat. They take the tank to a welding shop, but the shop determines that the damage is too extensive to repair. The shop explains that the salt water corrosion has compromised the metal, making it impossible to weld without causing further damage.
Thanks for the article tutorial. Do you think this might work for a 2 stage MTD snowblower fuel tank that is leaking around the seam where the two halves of the tank are joined together? The fuel tank is plastic, so I’m not sure what the best solution is. My pack of JB Weld 2-part epoxy says it’s fuel and petroleum resistant, but while searching YouTube I found your article specifically using the tank weld product. It definitely seems to have worked for your application!👍
I’m finding that this product holds for a few months and then starts to break down and becomes flimsy and completely detaches. I need to do this again for the 3rd time in almost a year. I know I should probably take down the tank and do a proper repair but it’s a 26 year old truck and I don’t want to open that can of worms.
Happens on trucks from road salt in the winter all the time. Use urethan sealer. Bonds to aluminum and contracts and shrinks with the cold and hot well. It’s used to seal windows to aluminum and other stuff like siding. I cover tanks where the bands or straps holding it on. Corrosion always happens between the bank and the rubber grommet.
I recently built a 226 gallon tank for my robalo 26′ center console. I have been told to linex (to expensive) or coat it with coal tar epoxy before installation. My tank was in similar shape but worse with actual pin holes. I can’t see where anything was done or coated originally to help preserve the factory tank.
