Jabsco 1L Accumulator Tank w/Internal Bladder - 30573-0000

Jabsco 1L Accumulator Tank with Internal Bladder – Model 30573-0000

The Jabsco 30573-0000 is a high-performance 1-liter (33 fl oz) accumulator tank designed to optimize pressurized water systems in marine, RV, and commercial applications. By acting as a pressure buffer, this tank effectively smooths water flow, eliminates pump pulsation, and significantly reduces noise and vibration from "water hammer" effects.

Equipped with a maintenance-free internal bladder, this unit stores a reservoir of air and water under pressure. This prevents your water pump from cycling on and off needlessly for small tasks like washing hands, which extends pump life and reduces battery consumption.

Smooth, Consistent Water Flow

The internal bladder stores pressurized water, reducing rapid pump on/off cycling. This results in:

• Steadier water pressure at faucets and showers

• Reduced pump noise and vibration

• Improved overall system comfort

Internal Bladder Design

The sealed internal bladder separates air from water, maintaining consistent pressure while preventing waterlogging. This design ensures reliable long-term performance with minimal maintenance.

Marine-Grade Construction

Built to withstand harsh marine environments, the 30573-0000 features:

• Corrosion-resistant materials

• Durable housing for vibration resistance

• Sealed construction for reliable onboard use

Compact & Easy to Install

With its small 1-liter footprint, this accumulator is ideal for tight spaces commonly found on boats and RVs. It installs easily into existing pressurized freshwater systems and is compatible with most Jabsco and other marine water pumps.

Key Benefits

• Smoother Water Delivery: Provides a steady, even flow of water to faucets and showers, offering better control over hot water temperatures.

• Quiet System Operation: Minimizes the "thumping" sound of the pump and reduces shock pressures throughout the plumbing.

• Extended Pump Life: By reducing the frequency of pump starts, the 30573-0000 lowers mechanical wear and tear.

• Universal Mounting: The internal rubber membrane allows the tank to be mounted in any orientation—horizontally, vertically, or even upside down.

• Easy Installation: Features "snap-in" port fittings for quick connection to new or existing systems.

Technical Specifications

Installation & Maintenance

This accumulator tank is intended for any pumped water system controlled by a pressure switch, such as the Jabsco Par-Max series. It features a standard tire valve (Schrader valve) at the end of the tank, allowing you to easily adjust the pre-charge pressure to match the "cut-in" pressure of your specific pump.

Pro Tip: For the best results, check the tank's air pressure once a season. Ensure the water pump is off and the system pressure is relieved before adjusting the air valve.
