Bladder-type accumulator tank for low-flow water systems. ½" MNPT connection, 125 PSI max, NSF food-grade materials. Made in the USA.
The Remco RACT-820-NPT-SB is a professional-grade bladder-type pressure storage vessel engineered to smooth out the water delivery in demand-driven freshwater systems. By holding water under pressure, the tank provides additional storage that assists the pump in meeting total system demand — reducing the wear and tear that comes from constant on/off cycling.
Compact enough to fit in tight spaces and mountable in any position with the included brackets, this tank installs anywhere on the pressurized side of your plumbing. Built from NSF-certified food-grade materials and factory tested for performance, it is equally at home in RV and coach water systems, marine applications, and residential low-flow setups.
⚠️ Note: This tank is not for use with Remco AQUAJET variable-speed pumps. Use with AQUAJET can cause the pump to continue running after flow is stopped, building extreme pressures that may result in leaks or pipe damage.
Minimizes hydraulic noise, water hammer, and pressure spikes throughout your plumbing system
Dampens rapid on/off cycling that wears out pressure switch-controlled pumps prematurely
Constructed from certified food-safe materials — safe for use in freshwater drinking systems
100% factory tested for flow and pressure performance before shipping
This accumulator tank is designed for freshwater applications only. Do not use with saltwater, chemicals, or non-potable water sources. Installing on a system that exceeds the 125 PSI maximum pressure rating may damage the tank or cause leaks. Always ensure your system pressure falls within the operating range before installation.
The RACT-820-NPT-SB is well-suited for a wide range of low-flow freshwater plumbing systems, including: RV & Recreational: • RV and coach water pump systems • Travel trailer freshwater lines • Motorhome on-demand pump setups Marine & Residential: • Boat and marine freshwater systems • Residential low-flow demand pump systems • Cabin and off-grid water supply setups Not compatible with Remco AQUAJET variable-speed pumps.
Installation is straightforward — no special tools required: 1. Choose Your Location: Select any point on the pressurized (outlet) side of your water pump. The tank can be mounted in any orientation. 2. Mount the Brackets: Attach the included mounting brackets to a wall, cabinet, or frame near your pump installation. 3. Connect the Tank: Thread the ½" MNPT fitting into your plumbing line. Use thread tape (Teflon) on the male threads to ensure a leak-free seal. 4. Secure the Tank: Fasten the tank body to the mounted brackets in your preferred orientation. 5. Restore Pressure & Test: Pressurize the system and check all connections for leaks. The tank ships pre-charged to 20 PSI and is ready to operate immediately. Tip: Install as close to the pump outlet as possible for maximum pulsation dampening benefit.
