In many cases water companies will be delivering in excess of this minimum requirement, but even at 1 bar, this isn’t always enough to sustain demand in larger residential properties, high rise buildings or commercial and industrial buildings where there are multiple water outlets.

Hello, I’m Frazer Ross and in this week’s 60-second knowledge booster video, I’m talking about calculating the pressure requirement. Having determined how much water we need, we then need to determine at what pressure we need to supply it at. This is made up of 3 things:

• Static head
• Pipework friction loss
• Discharge pressure required at the fitting

The static head is the high difference between the water source and the highest outlet in the building. Imagine a tube or riser full of water, the weight of the water in the riser due to gravity exerts a pressure that needs to be overcome before we can get water out of the top.

The pipework friction loss is the hydraulic loss from getting water from point A, through the system to point B.

The discharge pressure is the pressure required at the fitting, tap or shower head in order for it to function properly.

To help you select the right booster set for your specific project Dutypoint has created an online product selector.

Hi I’m Frazer Ross. In this week’s Knowledge Booster video, I’ll pick up from where I left off last week and will talk about determining the pressure requirement for new projects.

Once you understand the current standing pressure and the flow requirements for the property for which you are specifying then you need to calculate the pressure requirement, which is the sum of the static head, the height difference between the storage tank feeding the pressure booster and either the shower or tap at the highest point in the building, the required pressure at said highest outlet and the expected pressure loss from friction in the pipes.

Emergency or maintenance cover at peak demand also needs to be considered, for example, in a scenario where one pump fails and needs repair/replacement, how will the rest of the system deliver the required level of pressure.

On pretty much every project, you will need to make assumptions in order to be able to make this calculation but thankfully there are tools available to help you.

Hi I’m Frazer Ross. In this weeks 60 second Knowledge Booster I’ll talk about determining existing standing pressure and the flow requirement for new projects.

Before you can determine whether a pressure booster is required you’ll need to determine the current standing pressure and flow requirements for the property/site which you are specifying.

Standing pressure can be measured on-site, if it’s an existing property, or for a new build, you can contact the local water supply company. When calculating it on site it’s important to take into consideration whether the supply pipework is undersized and whether the mains pressure is likely to change significantly.

You then need to determine the flow requirements for the property, guidance is available within BS EN806 (Part 3) and other guides but essentially it is a calculation of the sum of all draw-off flow rates from the water appliances, taps, showers etc. that are/will be installed within the building, with allowance for probable simultaneous or peak demand flow, which is the worst-case scenario that could occur if all the taps, showers, etc. were used at once, a good example is sports stadia where demand could be much higher at half time. Consideration should also be given to the types of taps and showers installed, for example, thermostatic mixer showers need higher flow/pressure in order to function correctly.

Once you have these calculations you will need to calculate the pressure requirement which we’ll cover in next week’s video.

According to the official Ofwat Regulations, water companies must maintain a minimum pressure in the communication pipe of 7 metres static head, which is 0.7 bar.

In many cases water companies will be delivering in excess of this minimum requirement, but even at 1 bar, this isn’t always enough to sustain demand in larger residential properties, high rise buildings or commercial and industrial buildings where there are multiple water outlets.

Factor in the possibility that the water supply pipe is not big enough or partially blocked by limescale and the water supply to the property will be further restricted. High rise buildings in particular often experience a loss of mains pressure the higher you go up the building, which is less than ideal for the occupants of the penthouse apartments at the top!

This explains the need for pressure boosters in most occupied buildings larger than a typical UK house.

In this video, Jesse Freeman and Chris Lang discuss the many features and benefits of the new VT cold water booster set from Dutypoint.

The Dutypoint OPTIMISE Underground packaged pl­ant room provides a cost-effective, safe and efficient solution to pl­ant room space, and for installing water systems underground.

By combining industry-leading technologies, Dutypoint can offer a system which overcomes many of the challenges associated with underground p­lant rooms, with lower overall costs, unique safety features* and ease of maintenance.

Cutting-edge, cost-effective Heat Interface Units from Dutypoint Systems

The Dutypoint range of Heat Interface Units (HIUs) provide a highly efficient and reliable solution for delivering renewable energy to apartment complexes. Hot water produced by a centralised district heating plant is transferred via integral heat exchangers to provide on-demand domestic hot water, and heating is provided with either a direct or indirect connection to the central system. Units are available with either thermostatic or hydrothermic control.

Advanced automated manufacturing technology enables us to offer specially configured heat interface units for each project. Units can be specified for conventional radiator systems or under-floor heating, with water and heat metering and wireless communication, as well as a number of enclosure configurations to suit the space available in the installation.

Dutypoint have just commissioned the new 30kw surface water pump station protecting a manufacturing facility in the West Midlands.

These pumps are able to take surface water from facilities drainage system and move it into a storage lagoon at around 1000 litres per second!

The reason a pump station was required is because there is a very high water table and the manufacturing facility we are protecting has some very large pits with expensive machinery installed in them.

Also, by using Dutypoint’s new state of the art PLC control interface, the pump station can be remotely monitored, which enables our service team to closely watch the performance of the pump station via IOT.
