Introducing our new “Pent-A-Boost”

Continuous Product Development

We are firm believers in continuous product development and devote plenty of time ensuring that all of our products are the best that they could possibly be. We have improved an all-time customer favourite, our model Pent-A-Boost – compact domestic booster set.

Primarily designed for boosting water pressure for penthouse suites and other tall buildings, this unit requires minimal space for installation – e.g. stairwells, and will fit through a standard doorway.

We have anticipated and address the issue of stagnant water that can be associated with horizontal vessels, including the issue of potentially promoting bacterial growth by introducing a vertical flow through vessel.

We have introduced an automatic Bypass Valve as standard for all models, ensuring that water is always provided at mains pressure as a minimum, even in the event of planned or unplanned maintenance, or power failure.

We have listened to our customers and we know that some applications require higher pressure than we previously were able to supply, and so we have introduced higher pressure models. These now range from 1-10 bar at 1.0 l/s, and 1-8 bar at 2.0 l/s.

The new Pent-A-Boost is more efficient as we use IE5 motors in all of our pumps and all models we offer are variable speed.

All of this still within the same unique, compact footprint.

December 2018: Donation To ‘The Toy Project’

Merry Christmas from all of us, to all of you,

Here at Team Arrow, sustainability is very important to us.

For Christmas this year, we’ve decided to send e-cards instead of traditional paper cards, and have donated £1,000 to ‘The TOY Project instead’.

‘The Toy Project’ is a charitable organisation which helps children deal with their grief through play – providing toys for use by organisations involved with child bereavement. They provide toys for children in hospitals and hospices, children in refuge centers, provide toys for schools and nurseries and to vulnerable families.

Every year in the UK over 20,000 children under the age of 18 experience the death of a parent – that is around 60 children and young people bereaved of a mother or father every day. We know that ‘The Toy Project’ will put our donation to good use over the festive period.

For more info please head over to www.thetoyproject.co.uk

Arrow Union – Charity Walk

It wasn’t a walk in the park for us!

The Arrow Valves Team absolutely love working as a team and challenging ourselves. In honor of our 20th year of trading – we knew we needed a challenge. We organised a 20 mile walk, for 20 years, between two of the directors houses along the Grand Union Canal – hence our aptly named “Arrow Union” event.

On Sunday October 7th, we kick started the day bright and early in the morning, with pastries and orange juice, and full of smiles and optimism! Those of you who have been to visit us, may remember that our office is close to the Grand Union Canal, and so after a pit-stop and snacks here, we were raring to go again.

This trek definitely wasn’t ‘a walk in the park’, and by the end of it, there were plenty of sore feet! However, each and every team member finished the walk, together, and we were thankful for a lovely hot meal at the end! We are immensely proud of each and every walker.

We raised a fantastic £836.00 for our charity of choice, the Toy Project (click to read more ) from our wonderfully generous sponsors, and as promised, Arrow Valves have matched that amount and sent a further £836.00 to Macmillan Cancer Support.

Although we’ve completed the walk, our just giving fundraising page will stay open until our 20 year party in April next year so we’re hoping to raise even more. Visit it today.

How to protect your outside tap: a look at the Water Regulations

Any outside tap must be protected by a double check valve as a minimum – but when would you need a higher level of protection?

Contamination: Outside Taps

An outside tap – regardless of risk – should be protected by a double check valve.

The additional of a hose pipe that could potentially be submerged in water (such as tanks, ponds, swimming pools or rivers), creates the risk of backflow and therefore contamination to the mains.

As a guideline:
Any hose pipe used in a domestic setting would be fluid category 3 and therefore protected by a double check valve within the thermal envelope of the building.

Due to the higher potential risk of the fluids used in a non-domestic setting, as a guideline any hose pipes here would be considered a fluid category 5 risk and you would therefore need a physical air break in the system.

 

Do Consider –

·         The water companies take a risk assessed approach, and depending on the application, this could be downgraded

·         The addition of any chemicals or pesticides would exacerbate the risk

·         Bin stores, regardless of location, are fluid category 5

·         Irrigation systems with porous hoses that use no chemicals are considered a fluid category 4 risk and can be protected with a DB Pipe Interrupter

·         Whilst it is important to use hand held spray guns with self-closing mechanisms to prevent waste and misuse of water, these do not protect against contamination, and appropriate backflow prevention devices must be installed

As manufacturers of backflow prevention devices, we have a range of products and want to help find a solution for every application. Call us today.

“Boost-A-Break” – more powerful than ever!

More power with the same small footprint for any Fluid Category 5 application

BOOST-A-BREAK: Model BTAB with break tank and pump set. Fluid Category 5 protection with higher than before set pressure to help no matter what your application. 

Our “Boost-A-Break” model break tank and pump set, with AB air gap for Fluid Category 5 now boosts higher than ever with our new additions to the range. Primarily for backflow protection, but now will the added ability to boost pressure to higher elevated areas or high-pressure applications.

All the new models are still light and compact and have the same exceptionally small footprint, for easy installation within any plant room.

 

HIGHER PRESSURES

The 1 litre/second model now goes up to 10 bar pressure, and the 2 litre/second model now goes up to 8 bar pressure. Look at the performance of the full range above and select the model for your project! Applications include washdown, healthcare water fittings (showers, dialysis machines) and laboratories… to name a few.

Arrow Valves meets TimeBank!

“Be there, Be a volunteer”

At Arrow Valves, we are always looking for new ways to help charitable organisations and the community, and to give something back. In place of a financial donation, we wanted to give something extra – our time. TimeBank are national volunteering charity, and their goal is to transform the volunteering experience and make it a real force for change. They work with businesses to engage staff members in volunteering, connecting companies to local projects – helping communities.

On the 9th and 10th of April, several members of the Arrow Valves team headed over to Woodberry Down in North London, to help regenerate a community Garden.

This is what we were faced with…

As Adrian, one of the volunteers said, ‘it was a wet and miserable day and we had to take orders from strangers. The whole process looked daunting and impossible to achieve, but a group of strangers knuckled down, got covered in mud and grafted’. And we grafted! The days were spent weeding, shoveling soil, building wooden planters by sawing, hammering and nailing, lifting and shifting these around… and the finished product was incredible!

For more information on TimeBank, or to find out how you can get involved, please visit their website here.

Keep reading to find out what our team had to say:

Adrian – “By the end of the day we looked back on what was rows of bags to nice neat rows of purpose built boxes, ready to plant. Tired, dirty, wet but with an enormous sense of achievement and a proud respect for our fellow workmates.”

Laura – “The day provided the opportunity to push the boundaries of our comfort zones and learn new skills in an inspiring and rewarding environment.  Volunteering our time versus money whilst meeting genuine hard-working people, both as volunteers and members of the community, humanised giving back.”

Shadene – “It felt great to help out a community who really wanted something beautiful for their neighbourhood. I loved seeing members from the local housing coming down to help and show appreciation for individuals putting in the time and extreme effort without complaint. The experience was made even more enjoyable by my team members – we all had an amazing day! All in all a green thumbs up.”

Sophie – “A rewarding day for myself, my team and the local community we helped. All in all, a day well spent.”

Veronica – “It was a fabulous, hard but rewarding day, not only did I help out with a great scheme I found I also helped myself, fresh air and laughter after a cold winter was just the tonic!”

Whole Site (Zone) and Point of Use Protection

This blog is to help Consultants, Contractors and Installers understand how whole site (zone) protection and point of use protection are used within a building and why they are deemed necessary.

This blog is to help Consultants, Contractors and Installers understand how whole site (zone) protection and point of use protection are used within a building and why they are deemed necessary.

G15.25

The provision of zone or whole-site backflow protection should be in addition to individual requirements at points of use and within the system”.

Clause G15.25 is the guidance note in the water regulations that mentions these two key statements:

1 Whole site or Zone.

2 Point of Use.

Definitions:

Water Undertaker: The water board, the company responsible for supplying mains water to the boundary of a building or premises.

Fluid Categories: The classification of water and its potential health hazards, there are 5 recognized categories ranging from 1 to 5. With 1 being safe and 5 having the potential to cause serious health problems or possible death.

Potable Water: Water that is classed a wholesome water, or fluid category 1, water that is safe to drink and contains no harmful substances that will cause ill health. Water that the water board will supply to the boundary of the building as above.

Throughout the water regulations the text will refer to “fittings”:

A fitting is simply a device that is used to convey water from the water undertakers supply pipe at the boundary, this will be our pipe, but it also refers to any device used in the building, a tap, a washing machine, a sluice a pump set an outside tap and so on.

Cross Contamination: The risk that fluid from one fitting can mix with the fluid from another fitting.

 Upstream: Flow before a fitting

Downstream: Flow after a fitting

Backflow: Flow upstream that is in a direction contrary to the intended normal direction of flow, within or from a water fitting.

Risk Assessment: Based on the fluid categories above, a fitting will be assessed accordingly, and the correct backflow prevention device will need to be installed.

 The water as delivered to the boundary of our building is completely safe to drink. Under the water regulations, we must not waste, misuse, contaminate, unduly consume or erroneously measure the supplied water. For this blog we are mainly concerned with the contamination element.

Whole Site Protection (Zone)

Going back to clause G15.25 lets look at Zone protection and Whole site protection first. Whole site protection refers to the boundary of our building or the point at which the water undertakers pipe stops, under the water regulations it’s our duty to provide a single check valve or a double check valve at this point. However, this could vary with the severity or risk assessment of the building, generally in a multi-use building the single and double check valve will suffice, remember this is in addition to point of use protection that we will discuss further on. If the building was classed at a higher risk in general, then we may have to consider a RPZ valve (Fluid category 4) device for our whole site protection, still in addition to point of use protection.

Point of Use

For point of use protection, we must consider every fitting individually. We could adopt a very casual attitude in that the water undertakers supply is protected via our whole site device, this could be true. We could fit a fluid category 5 device and be completely safe, but we would not be protecting people within the building from cross contamination.

Every fitting then is risk assessed according to the severity of the water used in the final process, we should consider that a lot of fittings have inbuilt backflow prevention devices and would not need additional equipment. For example, a tap on a basin has an AUK2 airgap by default. A toilet cistern is interposed and is fluid category 5 by default. A washing machine may have a fluid category 3 device built in and so on. However, a bath in a domestic situation is fluid category 3, if the same bath is used in health care or assisted bathing then the risk becomes fluid category 5. The air gap on domestic tap would not suffice in a medical application, the same would apply to our washing machine if it were used in a medical application.

Based on our risk assessment, the correct backflow prevention device is fitted upstream of our fitting, no additional water take-off points must now be fitted downstream of this device.

There may be allowances within our building to further Zone protect rather than Point of use protect. For example, if we have a domestic washing machine and a dish washer in a fluid category 4 situation they must be protected via point of use devices (Figure1).

Figure 1

If we have 2 washing machines that are doing the same job within the building, the water board may allow 1 device to serve both units (Figure 2).

Figure 2

Summary

Point of use backflow protection is required, in addition to Whole site or Zone protection, each fitting must be risk assessed accordingly and the correct backflow prevention device fitted.

The water board must be notified of the intended works, this is the duty of the building owner or their appointed representative.

The Water regulations guide is an informative guide with many examples relating to fluid categories and the correct devices required.

Arrow Valves have an extensive knowledge of the water regulations, and an extensive range of products that comply with the regulations and satisfy both Whole Site (Zone) and Point of use protection.

More than just a ‘Standpipe…’

No power for your Fluid Category 5 application?
No problem for our Fluid Category 5 Standpipe!

…introducing our brand new Filling Standpipe – our Standpipe Assembly with an integral break tank with an AB Air Gap, making it suitable for Fluid Category 5 backflow protection.

This standpipe is designed for filling Fluid Category 5 applications, providing water under gravity, where there is no option for a power supply for an electrical pump.

Primarily designed for boat filling, but perfect for other category 5 applications where a DC pipe interrupter just won’t suffice, you will only need your cold water inlet pipe to run this standpipe.

Unlike traditional Standpipe Assemblies that usually come complete with a double check valve, you won’t need to install any additional Fluid Category 5 backflow protection device on the supply to this standpipe.

If you’re interested in this model or want information on the full range of Fluid Category 5 backflow prevention devices, such as our “Midi Break” for bin store wash down, please visit our Fluid Category 5.
