1 Litre Accumulator Tank
12573-3000
• Improves all multiple outlet pressure controlled water systems
• Gives smoother flow, quieter water systems
• Provides better control of hot water temperature
• Results in longer pump life, lower battery drain
• Simply fitted to new or existing systems
• Light and compact
• Supplied complete with ‘T’ fitting for 13mm (½’’) ID hose
The Jabsco Accumulator Tank is intended for
installation in any water system supplied by a pressure
switch controlled water pump, for example Jabsco
pressure pumps, as found on boats, caravans, motor
homes, coaches, and recreational vehicles.
The accumulator tank smoothes water flow and
reduces on/off cycling of the pump by reducing the
variation in pressure and flow between the pump and
outlets in the system.
The even flow of water gives better control of hot water
temperature especially noticeable with instantaneous
gas water heaters and showers.
The reduced on/off cycling reduces noise from the
pump motor, and from shock pressures (water
hammer). It also reduces battery drain, and gives
longer pump life.

Installation Instructions
1. MOUNTING - The Jabsco Accumulator Tank must
be mounted vertically.
2. LOCATION - The tank must be fitted in the outlet
line from the pump. Do not connect the accumulator
tank directly to the pump outlet port. Use flexible hose,
not rigid pipework, to isolate the accumulator tank from
any pump vibrations.
3. WATERTIGHT CONNECTIONS - PTFE tape must
be used when connecting either the ‘T’ fitting provided
or any other fitting to the ½’’ BSP externally threaded
outlet on the accumulator tank. Hose clips must be
used when connecting the hoses to the ‘T’ fitting.
4. DRAINING FACILITY - It is advisable to fit a drain
cock or plug in the lowest point of the water system to
make it easier to drain the water out of the
accumulator tank when the air cushion inside it has
been absorbed into the water.

To replace the air cushion:
1. Turn off the power to the water pump.
2. Open the tap farthest from the accumulator tank.
3. Remove the plug in the top of the accumulator tank.
4. Open the drain cock, if fitted, or loosen the pipe
joint on the pump delivery side, to drain the water
system.
NOTICE
• Hand tighten only. Do not overtighten top plug or ‘T’
fitting as this will damage the tank.
• Plastic or similar fittings only are recommended.
• Do not paint the accumulator tank as this may lead
to deterioration of the plastic material.

Do not overpressurise the tank. Pressures
over 125psi (8.5 bar) may rupture tank and
cause personal injury.
Maintenance
Over time, the air cushion will be absorbed. This is
apparent when the pump starts to cycle rapidly if only
a small amount of water is used, for example by a
leaking tap, or when an instantaneous gas heater is
being operated on maximum heat setting.
5. Replace plug and washer in top of the accumulator
tank.
6. Close the drain cock, if fitted, or re-connect the
pipe joint, and leaving the tap furthest from the tank
open, switch on the pump. When water is flowing
smoothly, close the tap. The system should then
shut off automatically.
