Where does HomeBoost get the additional water to increase the flow?

HomeBoost draws water from the mains water supply pipe to deliver an increase of flow into the property. If HomeBoost recognises poor flow (between 3L/min and 12L/min) it will activate the motor and increase the flowrate up to 12 L/min (the maximum allowed pumped flow directly on the mains). Where the flow turbine recognises more than 12 L/min, the signal is sent to the pump to sit in idle mode.

How does HomeBoost work? How does the pump increase the water flow?

HomeBoost uses smart technology to monitor the mains water flow rate into a property. The flow turbine inside HomeBoost recognises the incoming natural flow of water passing through the pump, a signal is sent to pump to convert this into flow rate. If HomeBoost recognises poor flow, between 3L/min and 12 L/min, it will activate the motor and increase the flow rate up to 12 L/min (the maximum flow rate allowed to be pumped directly from the mains). If the flow turbine recognises more than 12 L/min, the signal is sent to the pump to enter in idle mode.

If 6 L/min is coming into the property how does HomeBoost deliver 12 L/min out?

It all depends on what the incoming flow rate is. The lower the flow rate the more HomeBoost will lift it. For example, if you have 3 L/min the pump will increase this by up to 9 L/min.

Will installing HomeBoost or TapBoost reduce the pressure and flow for my neighbours?

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.

How to clean inline pump filters

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

HomeBoost has started making an unusual noise

All pumps will make some noise, as water is being moved at a high speed and being thrust out of a pump. Depending on the type of pump, water will be moved in different ways and therefore different pumps can make noises.

If the HomeBoost pump is making an unusual noise, it is worth checking the installation is correct and eliminate contributing factors to the operational noise such as transfer noise:

  • Pipework to and from the pump should be clipped and secure to help reduce any vibration transferring from the pump to the pipework during use.
  • A blocked filter washer on the inlet pipework will starve the pump of water which will increase the noise of the HomeBoost, ensure the inlet filter is free from debris should you notice the pump has become noisy! Learn how to clean inlet filters.
What type of hot water system do I have?

There are three main types of hot water system in the United Kingdom – gravity fed, mains fed: combination boiler, and mains fed unvented cylinder.

Gravity fed

  • If you live in an older property there’s a good chance you have a gravity fed system, renowned for poor pressure and flow.
  • These systems are identified by a hot water cylinder stored in an airing cupboard, and a large cold water storage tank, often located in the loft.

Mains fed: Combi boiler

  • Combination boilers are common and rely solely on mains pressure to deliver water around your home.
  • These systems are identified by a wall hung boiler.
  • In a combi boiler system hot water is available on demand, and there are no water storage tanks.

Mains fed: Unvented

  • Unvented systems require a separate hot water cylinder to store a quantity of hot water at mains pressure.
  • These systems are identified by a wall hung boiler and metal-clad hot water storage tanks and no cold water storage.

How can a HomeBoost fittings kit make installation easier

Using a HomeBoost fittings kit will ensure smooth and efficient installation. The kit includes high quality brass connectors and an isolating valve to ensure easy servicing, with the connectors designed to allow the pump to easily slide out when required.

Is the noise my HomeBoost pump is making normal?

We have designed our products to be as quiet as possible, but it is worth noting that there is some noise associated with the operation of our products. HomeBoost operates at 46dBA and has been awarded the Quiet Mark for being amongst the quietest in its category.

If you think your HomeBoost is noisier than it should be carry out the following –

  • Check the inlet filters are not blocked.
  • Check that nothing could be restricting the flow to HomeBoost.
  • Make sure that the pipework is securely clipped, and that HomeBoost isn’t in contact with anything other than the pipework.
Why is HomeBoost making a rattling noise?

If the pipework supplying the HomeBoost intelligent mains booster pump pump isn’t secured properly, the vibrations from the pump may cause it to rattle.  Make sure that the pipework is clipped.

My inline pump (TapBoost, HomeBoost, CombiBoost) isn’t turning on when I open an outlet. What should I do?

First, check the power supply to the pump.

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

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.
