RT40 Clack Retention Tank: Enhance Water Treatment Efficiency with Durable 40-Gallon Capacity
Designed specifically for water treatment systems, the RT40 Clack Retention Tank offers a reliable and efficient solution for managing chemical feed and system backwash. Unlike generic tanks, this 40-gallon capacity retention tank ensures optimal chemical retention and system protection, making it an essential component in chemical feed pumps and related water softener setups. Its robust build and precise sizing make it ideal for maintaining system balance and longevity.
Key Benefits
- Improves chemical feed system stability by providing consistent retention volume
- Protects water softener components from pressure fluctuations and backwash surges
- Enhances system efficiency with a durable 40-gallon polypropylene construction
- Easy to integrate with existing chemical feed pumps and accessories for seamless operation
- Reduces maintenance frequency by minimizing sediment buildup and wear on system parts
- Compact 21" x 42" size fits standard installations without requiring extra space
How It Works
The RT40 Clack Retention Tank acts as a buffer within your water softener or chemical feed pump system, holding up to 40 gallons of solution to ensure steady chemical dosing and pressure regulation. When the system cycles through backwash or regeneration phases, the tank absorbs pressure spikes, preventing damage to sensitive components and maintaining consistent flow rates.
By retaining chemicals temporarily and releasing them at controlled rates, this retention tank helps maintain optimal water treatment performance and extends the life of your system’s parts.
What to Expect
Immediately after installation, you will notice smoother operation in your water treatment system with reduced pressure fluctuations. The tank’s capacity allows for better chemical retention, resulting in stable dosing during all cycle phases.
Over the first few weeks, the system will experience fewer interruptions or unexpected shutdowns related to pressure surges. Long-term, the RT40 retention tank requires minimal maintenance, offering reliable performance and helping to reduce wear and tear on pumps and valves for years to come.

FAQ & Safety
Is the RT40 compatible with all chemical feed pumps?
It is designed to integrate with most standard chemical feed pumps and water softener systems, but always verify connection sizes and specifications before purchase.
How often should the retention tank be inspected?
Regular visual inspections during routine system maintenance, typically every 3 to 6 months, help ensure ongoing performance and identify any wear early.
Can the tank handle high-pressure systems?
The RT40 is built with pressure-resistant polypropylene housing suited for typical water treatment system pressures; extreme pressures should be evaluated separately.
Is installation difficult for a homeowner?
Basic plumbing and system knowledge is recommended; professional installation is advised for best results and safety.
Does the tank require cleaning?
Periodic flushing during system maintenance can help prevent sediment buildup, but the tank’s materials resist corrosion and buildup effectively.
