TapBoost SupportWe're here to help

Yes, TapBoost can be used to boost the hot when the pressure is lower than the cold to a single outlet. However, at a mixer outlet you would need to ensure that a non-return valve is used on the cold side.

TapBoost is not suitable for boosting multiple outlets in a system. However, if you do want to boost the hot water throughout the whole system across multiple outlets, other products are suitable.

Please see the product selector.

TapBoost is a flow boosting product therefore, it would not improve the pressure of a unvented system. If you require a product that will improve pressure, please refer to our product selector.

TapBoost is a flow boosting product therefore, it would not improve the pressure of a combination boiler system. If you require a product that will improve pressure, please refer to our product selector.

TapBoost is a flow improving product, not pressure therefore, it will not work for this. If you require pressure boosting, please refer to our product selector to assist you in finding the right product.

TapBoost is only suitable for a single outlet therefore, it would not be suitable to boost the incoming mains to the whole house. Please see the TapBoost installation manual for more information.

Please refer to our product selector to assist you in finding the right product.

TapBoost can be used on a hot water gravity feed to a tap providing it is fitted in line to a single outlet and has a minimum of 1.2 L/min flow rate to activate.

TapBoost can be used in an unvented system however, it should only be fitted to a cold-water outlet as it cannot be installed on hot water pipes/outlets from an unvented system. Please note, TapBoost requires a natural flow of 1.2 L/min from any outlet to activate. The hot water supply from an unvented system can be improved by boosting the cold mains into the cylinder, this can be achieved by installing a TankBoost.

If installed after the boiler and inline to supply with a single outlet, TapBoost is suitable to be used with combination boiler systems to boost either hot or cold outlets. Please note, TapBoost requires a natural flow of 1.2 L/min from any outlet to activate.

TapBoost can be fitted in a hot system, however, only to boost a single outlet. Please refer to the product selector.

TapBoost can be installed on 22mm pipework to either the inlet and/or the outlet of the pump. To do so, you will need to use 15mm to 22mm converter fittings. You can purchase a TapBoost inlet/outlet 15mm to 22mm convertor kit separately, which includes:

• 1/2″ to 22mm compression tap connector
• 22mm x 3/4″ straight tap connector
• 3/4 x 1/2″ brass bush
• 3/4″ flat washer.

Example Installations using the Salamander Pumps’ TapBoost inlet/outlet 15mm to 22mm convertor kit are below:

Having a mains water booster pump does not affect the water pressure next door. If a property has a pump installed, they are not actually siphoning your supply, just using a pump to increase their own water pressure. When the pump is running and using water, it may cause a slight drop in pressure for the neighbour, but so small, its barely noticeable if at all.

Blocked filters can make our products slow to activate and water to become less powerful. Cleaning the filters can resolve these issues.

The TapBoost pump is IPX4 rated and the power supply unit is IPX0 rated. The power supply unit and plug must be protected from water and moisture. Please refer to the installation manual for more information.

Despite its name, TapBoost can be used for various poorly performing outlets. Examples include (but are not limited to) toilet cisterns, kitchen appliances and some electric showers (please refer to the *installation manual* for more info regarding the limitations when it comes to electric showers).

TapBoost is designed to boost the water flow rate rather than pressure. TapBoost does provide an increase in pressure, but this is dependent on incoming pressure.

A minimum natural flow rate of 1.2 L/min from the outlet is required for TapBoost to activate.

Unlike HomeBoost which adjusts its speed to continuously deliver 12 L/min, TapBoost runs at a constant speed. This means that the boosted flow is dependent on the incoming natural flow. For example:

When the incoming natural flow is 1.2 L/min TapBoost will boost the flow to up to 7 L/min.

When the incoming natural flow is 4 L/min it will boost the flow to 8 L/min.

The graph below gives full details of what boosted flow can be expected given the incoming flow.

When the incoming natural flow reaches 11 L/min, TapBoost will go into idle mode and stop boosting the flow to ensure it is never pumping more than 12 L/min, remaining in line with the Water Regulations.

The temperature of the water passing through TapBoost pump should be between 4°C – 60°C. Temperatures outside of this range may cause damage to the pump.

TapBoost operates at 34dBA. Learn more about TapBoost and other products from Salamander Pumps MainsBooster range.

TapBoost should never be installed to restrictive or collapsed pipework or supply, such as a lead main.

Yes, TapBoost can be installed on a shared water main as it should only be used for a single outlet within one property therefore, it should cause minimal to no disruption to other outlets and properties within the shared main.

TapBoost can be installed on a hot or cold outlet in a gravity-fed system. However, there must be a minimum natural flow of 1.2 L/min from the outlet to be boosted.

TapBoost can be installed in combi boiler systems to boost either a hot or cold outlet.

TapBoost cannot be installed on hot water pipes/outlets from an unvented system – TapBoost should only be fitted to a cold-water outlet in unvented systems.

There must be a minimum natural flow of 1.2 L/min from any outlet to be boosted.

Yes. TapBoost can be installed in certain zones within a bathroom, however the plug/power supply must be outside of the bathroom and the installation must adhere to the latest I.E.E. electrical regulations. Refer to the installation manual for more information.

TapBoost is not suitable for boosting multiple outlets.

If multiple outlets suffer with poor performance in a mains-fed system a larger inline pump or accumulator tank should be installed – click here to view our full MainsBooster range.

When more than one outlet suffers with poor water performance in a gravity-fed system then a bathroom or whole house pump should be installed – click here to view our full GravityBooster range.

Some electric showers are restrictive so it is best to check with the manufacturer as you may already be receiving the maximum allowable flow rate. In which case, TapBoost would not be beneficial. If you are not receiving the maximum expected flow rate from your electric shower, HomeBoost is the most compatible for boosting the water to an electric shower. It will deliver up to 12L/min and 1.6 bar.

Yes, TapBoost can be used to boost outlets providing drinking water such as kitchen taps.

TapBoost can be used on communal supplies provided that it is only being used to boost a single outlet within one property, as highlighted by the typical installations image.

TapBoost can be installed horizontally or vertically however for optimum performance it is better fitted vertically. Never install TapBoost upside down or against the direction of flow.

No, two TapBoost pumps in-line will not deliver double the flow and TapBoost must not be installed in this way. If a single TapBoost does not provide adequate flow, please consider one of our other products:

Our MainsBooster range features larger inline pumps and accumulator tank which will provide greater flow rates in mains-fed systems.

Our GravityBooster range includes pumps which will deliver higher flow rates in gravity-fed system

TapBoost should be fitted as close to the poorly performing outlet as possible. Correct installation is essential for safe operation and a trouble free system. It is therefore important to read “Installation and warranty guide for TapBoost” thoroughly and ensure you comply with it.

Yes. The power pack and cables supplied with TapBoost must be used to power the pump. The supplied power pack and cables have been certified for use with TapBoost to ensure that they comply to the UK safety standards. The use of other power packs will invalidate the warranty.

Yes, the filter prevents debris and foreign objects entering the pump. Should the filter become blocked it can be removed for cleaning and then replaced. A spare filter is also provided in the box.

TapBoost is supplied with a filter pre-fitted to the inlet and a spare filter in the box. The flat face of the filter should be inserted into the inlet port until the flat face sits flush with the pipe stop.

TapBoost has a 15mm compression fitting on the inlet and a ½” BSP male connection on the outlet. Learn more from “Installation and warranty guide for TapBoost“.

TapBoost has a 15mm compression fitting on the inlet to allow installation directly onto pipework. The outlet has a ½” BSP male thread allowing any suitable connection to be attached. When installed on mains water applications, no detachable hose sets should be used. If a flexible hose is used for connection to a gravity fed system, it should be no longer than 300mm.

The 15mm compression fitting on the inlet allows TapBoost to be installed directly onto pipework and the ½” BSP male connection allows flexibility for TapBoost to be installed in a range of applications, allowing TapBoost to be adaptable depending on the installation requirements.

The TapBoost power supply unit has a green LED which will illuminate when there is power to the supply unit.

The TapBoost pump is fitted with a blue LED to indicate its status. The image shows the location of the LED.

When the pump is in ‘standby mode’ (electrical supply to the pump but the outlet is not open) the LED will remain solid for 5 minutes. After 5 minutes the LED will turn off, but the pump will remain in ‘standby mode’.

A fast-flashing LED indicates that the pump is in ‘boosting mode’ (outlet is open and TapBoost is boosting the flow).

When the outlet is closed, TapBoost will then enter ‘standby mode’ where the LED will remain solid for 5 minutes as described above.

TapBoost intelligently monitors the flow of water. If the flow reaches 11 lpm or more, it will enter ‘idle mode’ indicated by a slow pulsing blue LED. The pump continues to monitor the flow but will not provide any additional boost. If the flow drops below 11 lpm, the pump will again switch to ‘boosting mode’ indicated by a fast-flashing blue LED.

First check to see if there is a green light on the transformer unit.

If there isn’t then:

• Check the plug is in the socket fully and that the socket is switched on
• The fuse in the plug hasn’t blown
• The power cable is fully connected to the transformer

If there still isn’t a green light, then the power cable will need to be replaced so please call us on 0191 516 2002.

If the green light is illuminated on the powerpack but the TapBoost still isn’t activating then please check to see if the blue light on the top of the pump is lit.

If it isn’t:

1. Check that the cable from the pump is fully connected to the powerpack
2. Then switch power off at the plug and wait 2 minutes and re-establish power supply to the pump

If the TapBoost still isn’t activating then you need to call us 0191 516 2002.

If the blue light is illuminated then please check the flow rate to the outlet, you can find details of how to do that here.

If your flow rate is more than 1.2L/min and the pump still isn’t activating then please call us on 0191 516 2002.

If your flow rate is less than 1.2 L/min then TapBoost won’t work as it needs this minimum flow rate to activate the pump.

In normal operation TapBoost is relatively quiet so if it has become noisy it could be because one of the following:

• Air in the system – Switch the pump off at the wall and run the water through the outlet for several minutes to clear any trapped air.  Then switch the power back on.
• A blockage or restriction – Isolate the pump from the water supply, remove the filter washer and check for debris.  Clean the filter or if necessary replace it with the spare filter supplied with the pump.  Reconnect the pump.
• Vibration against the pipework – if possible, secure the associated pipework.

If TapBoost continues to run when the outlet is closed please check the following:

• That the outlet is fully closed.
• If the outlet is fully closed and the pump continues to run, switch off the electrical supply to the pump, leave for 2 minutes and then switch the power back on.  Run the outlet and fully close it.

If this doesn’t solve the problem then there may be an issue with the pump, so please call us on 0191 516 2002.

First, check the power supply to the pump.

Then check the natural flow of mains water is sufficient to activate the pump.

• TapBoost requires at least 1.2 L/min to activate
• HomeBoost requires 3 L/min.

In compliance with the Water Supply (Water Fittings) Regulations 1999, our range of inline pumps will not pump water if the natural mains flow rate is greater than 12 L/min.
