Customer Questions & Answers
-
Question:
What is the purpose of the SEAFLO Accumulator Tank?
Answer: The SEAFLO Accumulator Tank is designed to smooth out water flow and reduce pump cycling. It acts as a buffer that stores pressurized water, which can be released on demand, providing consistent water pressure. This is particularly useful in situations where water is drawn intermittently, such as in RVs, boats, and off-grid systems. By reducing pump cycling, it can enhance system efficiency and prolong the life of your pump. -
Question:
How does the internal bladder work in the accumulator tank?
Answer: The internal bladder in the SEAFLO Accumulator Tank is a flexible barrier that separates water from the compressible gas within the tank. As water pressure increases, the bladder expands, allowing the tank to store potential energy. This mechanism helps maintain steady water pressure and reduces the frequency of pump activation. This is beneficial in ensuring a steady flow when multiple fixtures are used simultaneously, such as in showers and faucets. -
Question:
Can this accumulator tank be used in all water systems?
Answer: While the SEAFLO Accumulator Tank is versatile and compatible with various water pump systems, it's essential to ensure that your pump operates at or below the tank's 125 PSI rating. It's ideal for use in RVs, boats, and agricultural setups. However, for specialized systems, consulting your system specifications can ensure optimal performance and compatibility. -
Question:
What are the benefits of reducing pump cycling?
Answer: Reducing pump cycling with the SEAFLO Accumulator Tank can lead to significant benefits, including extended pump lifespan, improved energy efficiency, and minimized wear and tear. This is crucial in systems where the pump is frequently turning on and off. For instance, in an RV, the tank can maintain stable pressure during water use, allowing for a more comfortable experience without the noise and wear associated with constant cycling. -
Question:
What size or capacity do I need for my application?
Answer: The SEAFLO Accumulator Tank has a capacity of 23.5 oz (0.75 L), which is suitable for small to medium systems where space is limited. For applications like RVs or small boats, this size can sufficiently buffer pressure without taking up excessive space. If your system involves higher water demand, consider multiple tanks or larger capacity options to ensure consistent performance. -
Question:
Is installation of the accumulator tank complicated?
Answer: Installation of the SEAFLO Accumulator Tank is generally straightforward and does not require specialized tools. It can be plumbed into the water system's pressure line. Detailed instructions are typically provided with the tank, guiding users through the process. For those familiar with basic plumbing, setting it up in scenarios like RV water systems can be done efficiently without professional help. -
Question:
How does temperature affect the performance of the accumulator tank?
Answer: Temperature can influence the air pressure inside the accumulator tank. High temperatures can increase air pressure, while low temperatures can decrease it, potentially affecting water flow consistency. It’s recommended to monitor the tank regularly, especially in fluctuating temperatures, to maintain optimal performance. This is particularly important for boating applications where temperatures can vary widely. -
Question:
What materials is this accumulator tank made from?
Answer: The SEAFLO Accumulator Tank is constructed from durable materials designed to withstand the rigors of various environments. The exterior casing is typically made from a resistant plastic or metal, ensuring longevity. Internally, the bladder is crafted from a flexible rubber or synthetic material, providing reliable performance. This durability is crucial in harsh conditions found in marine or outdoor applications, ensuring the tank remains functional over time. -
Question:
Can I use the SEAFLO Accumulator Tank for both fresh and saltwater systems?
Answer: The SEAFLO Accumulator Tank is primarily designed for use with fresh water systems. While the durable materials can withstand some exposure to saltwater, prolonged use in saltwater environments is not recommended as it can lead to corrosion and degradation. For marine applications, consider using tanks specifically rated for saltwater to enhance longevity and performance. -

Where can I buy SEAFLO Accumulator Tank Water Pump Flow Control in Sierra Leone?
Answer: You can purchase the SEAFLO Accumulator Tank Water Pump Flow Control with Internal Bladder from Ubuy in Sierra Leone.
