Salamander AccuBoost Tank Connector Kit – Connect Multiple Vessels, Expand Capacity, All AccuBoost Models

The Salamander AccuBoost Tank Connector Kit (TNK-CON-KIT) is a genuine Salamander Pumps accessory that allows multiple AccuBoost accumulator vessels to be connected together, increasing total water storage capacity and extending boost duration for higher-demand properties. The kit contains a hose and a Salamander vessel connector unit for joining an additional vessel to the system via a T on the vessel port of the pump. Maximum combined vessel capacity is 900 litres when using this kit. All connected vessels must be set to the same pre-charge air pressure. For flow rates above 36 l/min, Salamander recommends connecting the additional vessel directly to the property pipework rather than via this kit. Compatible with all AccuBoost models — pumped and unpumped — in both Combi and Unvented configurations.

Key Features
Connects Multiple AccuBoost Vessels — Increases Total Water Capacity
The TNK-CON-KIT enables two or more AccuBoost accumulator vessels to be connected together, combining their stored water capacity to serve higher-demand properties where a single vessel would exhaust too quickly. The additional vessel connects via a T-piece on the vessel port of the pump (for pumped installations). Salamander's installation manual notes that for flow rates over 36 l/min, it is recommended to connect the second vessel directly to the property pipework rather than via this kit — consult the manual for the appropriate configuration for your target flow rate.
Multiple vesselsHigher total capacityT-piece connection
Kit Contents — Hose and Vessel Connector Unit
The TNK-CON-KIT contains a hose and a Salamander vessel connector unit for joining an additional accumulator to the system. The connector routes the additional tank into the system via a T on the vessel port, ensuring both vessels charge and discharge in a balanced manner when connected through the pump outlet side.
Hose includedConnector unit included
Pre-Charge Pressure Must Match Across All Connected Vessels
Salamander's installation manual specifies that when multiple vessels are connected, the pre-charge air pressure within all vessels must be set to the same value. If vessels are connected with different pre-charge pressures, one vessel will dominate the discharge cycle, the other will not contribute effectively, and system pressure behaviour will be unpredictable. Check and equalise the pre-charge pressure in each vessel before commissioning a multi-vessel installation.
Match pre-charge pressureAll vessels equal
Maximum Combined Capacity — 900 Litres
Salamander's installation manual specifies that the maximum combined capacity of multiple connected vessels should not exceed 900 litres — equivalent to two 450-litre vessels. For installations requiring greater than 36 l/min total flow, connecting the second vessel directly to the property pipework (not via the kit) is the recommended approach. Only one pump can be fitted per installation regardless of how many vessels are connected.
Max 900L combinedOne pump only
Genuine Salamander Part — Compatible with All AccuBoost Accumulator Models
The TNK-CON-KIT is a genuine Salamander Pumps OEM accessory, referenced by part code in the official AccuBoost Installation and Warranty Manual. It is compatible with the full AccuBoost vessel range and both pumped and unpumped configurations (note: connection method differs between pumped and unpumped — refer to Figures 19a and 19b in the AccuBoost installation manual for the correct pipework arrangement for your configuration).

Frequently Asked Questions
Do I need this kit to connect a second vessel?
For pumped AccuBoost installations, Salamander recommends using the TNK-CON-KIT to connect a second vessel via the T on the vessel port of the pump — this is the simplest and most integrated method. However, for flow rates over 36 l/min, Salamander recommends connecting the additional vessel directly to the property pipework (not through the pump T-port) — in which case this kit is not required and separate pipework fittings should be used instead. Consult the AccuBoost installation manual (page 20) for the correct method for your target flow.
How many vessels can I connect?
Salamander's installation manual states the combined total should not exceed 900 litres (equivalent to 2× 450L vessels). Only one pump can be fitted per AccuBoost installation, regardless of how many vessels are connected. If multiple vessels are to be connected to a pumped unit, they should be connected after the outlet from the pump.
Why does the pre-charge pressure need to match?
The pre-charge air pressure in the bladder determines at what mains pressure each vessel begins to discharge stored water. If two vessels have different pre-charge pressures, one will start discharging at a lower system pressure while the other remains charged — effectively meaning only one vessel contributes at any given time. Equalising pre-charge across all vessels ensures both contribute proportionally and the system behaves as a single, larger unit.
Can I use this kit on an unpumped AccuBoost installation?
Yes — the TNK-CON-KIT is compatible with both pumped and unpumped installations, but the connection arrangement differs. On pumped installations (Figure 19a in the manual), the additional vessel connects via the T on the vessel port of the pump. For unpumped configurations, refer to the relevant diagram in the AccuBoost installation manual for the correct arrangement.
Is this the same hose as the TNK-HOSE replacement hose?
The TNK-HOSE is a standalone replacement hose for any AccuBoost model. The TNK-CON-KIT includes a hose plus the Salamander vessel connector unit — it is a complete kit for adding a vessel, not just a hose replacement. If you only need a replacement hose for an existing connection (not adding a new vessel), the TNK-HOSE is the appropriate part.
