Leading plumbing and drainage manufacturer, Wavin, has expanded its plastic push-fit offering with the launch of its fifth-generation fitting, Hep2O Keyless.

This new range features an innovative two-stage twist and push functionality, eliminating the need for a demounting key and offering a smaller, more compact design. Hep2O Keyless fittings can be purchased in a pre-locked position, allowing for faster and easier installations.

Previewed at the InstallerSHOW 2024, the Keyless range retains much of the trusted functionality of the original Hep2O line and is compatible with a wide range of plastic and copper fittings. The development of these fittings was guided by feedback from plumbers and installers, addressing common challenges such as lengthy installation times and working in confined spaces.

The new Keyless range is backed by a 50-year guarantee and features Wavin’s In4Sure technology, ensuring secure joints with a distinctive ‘rumble’ during installation. New features include an optimised flow rate and robust plastic that prevent fittings from dismounting due to water hammer.

While the original Hep2O range remains a popular choice, Wavin is committed to providing merchants with flexible options that meet the diverse needs of individual projects.

Steve Harris, Technical Support Engineer at Wavin said: “Developing this range in-hand with tradespeople has been key. We’re excited to launch the next generation of our Hep2O fittings, enabling merchants to offer their customers a variety of solutions tailored to specific project requirements.”

For decades, conventional water traps (P-traps and U-bends) have been the standard way to prevent foul sewer gases from entering living spaces. However, they come with a set of inherent problems – over time the water seal can evaporate, siphon off, leak or be displaced by movement, which compromises the seal and allows unpleasant odours back into the building.

That’s where HepvO comes in. Rather than relying on standing water to create the seal, the HepvO Self Sealing Waste Valves uses a dry-seal, self-sealing elastomeric membrane to block sewer gases.

How HepvO Works:

  • When wastewater flows through – water pressure pushes the membrane open, allowing the waste to discharge
  • Once the flow stops and pressure returns to normal, the membrane automatically closes again, forming an airtight seal between the drainage system and living space
  • Because there’s no stagnant water sitting in a trap, there’s no risk of evaporation, siphonage or displacement, so the seal remains reliable over long periods

Key Benefits for Installers and End-Users

Reliable odour protection and hygiene

Since the valve doesn’t depend on water, it cannot dry out or lose its seal. It permenately prevents sewer gases, which can carry harmful bacteria/viruses, from re-entering the property. Because there’s no water to stagnate, there’s less chance of bacterial growth or foul smells associated with standard traps.

Flexible and space-saving installation

He HepvO’s valve’s in-line design and compact form factor makes it ideal for tight or awkward spaces. It can be installed vertically or horizontally depending on the orientation.

Versatility – not just for basins and sinks  

HepvO isn’t limited to traditional sanitary fixtures. It’s also suitable for condensate drainage from boilers, air-conditioning units, or other household systems – where the flow might be intermittent or minimal.

The HepvO’s Self Sealing Waste Valve represents a significant evolution in plumbing design. By replacing the traditional water trap with a self-sealing membrane, HepvO removes many of the limitations of conventional traps – no more worries about drying out, siphonage, leaks or displacement.

Given the growing importance of hygiene, ventilation, and space saving solutions in modern building design – especially in apartments, retrofit bathrooms, and compact living – HepvO offers a compelling alternative to age-old traps.

Product Overview:

Wavin Tigris K5/M5 is the next generation of press-fit plumbing and has been designed with installers and engineers at mind. The system is suitable for use in potable water, heating, secondary circulation, and HVAC applications It is essential these systems are installed to the highest standards, and testing is a crucial, often overlooked, part of the installation stage. Having listened to the challenges experienced by installers and engineers on site, including use of wrong tools, pressure testing with water and the hygiene requirements, and pressure loss by fittings – Wavin have created a fitting that meets the customers’ needs and eliminates their pain points.

The one-pipe-fits-all Tigris product family:

With Tigris, Wavin offers a complete range of fittings, all perfectly compatible with their multi-layer composite pipe systems. The Tigris family of fittings are available in a wide range of sizes from 16-75mm and are designed to offer the most reliable connection for their specific applications, but can be mixed and matched where required.

Utilising the reliable and tested Radial Press-Fit technology at it’s core, Wavin Tigris fittings have evolved to make installation quick, easy and most of all reliable.

Main Features:

Acoustic leak alert: The 80-decibel acoustic leak alert whistle, designed to easily identify unpressed fittings using an air pressure. This feature ensures that installers can reliably and efficiently detect unpressed fittings in the loudest environments. Giving installers a quick, cost effective, and efficient method to test one section of a building at a time, and without using water. Tigris K5/M5 is the first system to offer this innovative feature to streamline the overall pressure testing process.

In4Sure 360°: K5 fittings incorporate a new transparent section as part of the body to give installers a quick visual to check the pipe is inserted correctly. The fittings also incorporate a ‘leak path’ so unpressed fittings can also be visually identified if water testing is preferred by the installer.

Opti Flow: The Opti Flow feature ensures a 50% greater flow rate when compared with K1/M1Designed to deliver optimal flow performance through the fittings, this is especially relevant for smaller pipe diameters and will insure a higher total system performance. This is particularly beneficial for high-rise projects where there’s increased demand on the pumping system to supply water to upper levels.

Multi Jaw: Tigris K5/M5 fittings can now be pressed with common pressing profiles including U, Up, H, TH and B – ensuring installers do not require investment in new tooling. K5 fittings have a PPSU body and M5 fittings are DZR brass.

Ultra Seal: The reliability of the O -rings sealings is tested with a lifetime simulation test under extreme conditions. Tested to 110°C which is far above the required max temperature of 95°C.

Modernising the pressure testing process:

Pipelines have been historically tested using water pressure, a method that comes with great risk. The greatest being legionella, a water-bourne bacteria that can cause a potentially fatal lung infection in those who breathe in infected water droplets. Evidence suggests that this bacteria could develop if pipes aren’t effectively dried after water-pressure testing. Tigris offers a groundbreaking alternative to this.

For Contractors:

The Tigris K5 design has been optimized for speed and ease of installation, helping contractors to complete projects on time and ultimately save on labour costs. The Acoustic Alert feature enables contractors to test with air easily during the build process a section at a time (prior the final pressure test) which is a major benefit on a large build. The 80-decibel Acoustic Alert Whistle enables easy identification of unpressed fittings during an air pressure test – even in the loudest environments. Tigris K5/M5 is the first system to offer this innovative feature to streamline the overall pressure testing process. Tigris also demonstrates sustainable credentials with the lifetime assessment report showing a life span in excess of 100 years.

Wavin Tigris K5/M5 is the next generation of press-fit plumbing that will blow you away. Wavin has solved the biggest barrier of air pressure testing with a game changing approach, the first and only fitting with an acoustic leak alert to detect unpressed fittings in the loudest environments. On top of that, we built in features to create an industry leading fitting. Getting the connection right first time is even easier with features such as the 360° window where you can see the pipe is correctly inserted and we solved the tooling issue too. Supported with BIM Revit files for efficient design and EPDs for sustainability assessment – Tigris K5/M5 offers benefits not only to contractors but engineer, specifiers, and building owners too.

The Ultimate Guide to Continuously Operated Recirculated Systems

Introduction

Continuously operated recirculated systems, also known as secondary hot water circulation or ring main systems, are an essential component in modern plumbing. These systems ensure that hot water is readily available throughout a building while promoting better hygiene. In this guide, we’ll explore how these systems work, where they are commonly used, and why they are a valuable addition to any plumbing skillset.

Applications of Continuously Operated Recirculated Systems

These systems are particularly popular in large sanitary environments such as healthcare facilities and hospitality settings. Their design significantly reduces the risk of bacterial growth in the pipes, ensuring a hygienic water supply. This makes them indispensable in settings where the cleanliness of the water is paramount.

How Do They Work?

Continuously operated recirculated systems use a pump to circulate hot water through the pipework continuously. This constant flow prevents stagnation and maintains high water temperatures, which inhibits bacterial growth. By reducing opportunities for bacteria to thrive, these systems also lower the risk of Legionnaire’s disease.

Understanding Legionnaire’s Disease

Legionnaire’s disease is a severe form of pneumonia caused by the Legionella pneumophila bacteria, often found in stagnant water. The disease can be life-threatening and is contracted by inhaling water droplets containing the bacteria. Continuously operated recirculated systems combat this by maintaining a water temperature of at least 60°C, which prevents the bacteria from forming.

Ensuring Hot Water Quality

Unlike other hot water systems, continuously operated recirculating systems are easier to disinfect. Two main approaches can be employed:

  1. Thermal Disinfection: Designed to withstand temperatures up to 70°C, the system can be disinfected by heating the water to this temperature and rinsing each tap or sampling point for at least three minutes.
  2. Component Quality: Using high-quality components like the PE-Xc multilayer pipes ensures exceptional performance and longevity.

The Role of Tigris K5

Tigris K5 is a multi-layer composite pipe designed for potable water and heating applications. It offers several advantages over traditional copper piping, such as:

  • Five-layer construction: Includes an inner layer of cross-linked polyethylene, an outer layer of HDPE, and an aluminum layer in between.
  • Oxygen diffusion resistance: Prevents oxygen from entering the water system, reducing the risk of corrosion.
  • Thermal expansion comparable to copper: Ensures stability in varying temperatures.
  • Flexibility and fewer fittings: Speeds up installation and lowers material costs.

Unique Features of Tigris K5

  • Acoustic Leak Alert: Emits a loud whistle to identify any unpressed fittings.
  • Opti Flow: Enhanced inner bore improves flow performance.
  • Multi Jaw: Can be pressed with all common profiles.
  • Easy Fit: Allows for easy pipe insertion without calibration.
  • In4SureTM: Provides clear visual cues for unpressed sleeves.
  • Ultra Seal: Offers reliable O-ring sealing, tested beyond market standards.
  • Pipe Grip: Ensures pipes stay in position before pressing.

Providing Hygienic Water Supplies Across the UK

Traditional hot water systems can foster bacterial growth due to stagnant water. Continuously operated recirculated systems maintain water temperatures above 60°C and ensure constant water movement, significantly reducing this risk. They also guarantee consistent water pressure and availability, making them a superior choice for maintaining a hygienic water supply.

Wavin have added a new range of manifolds to their innovative Tigris Press fit range. With options for 2 to 4 ports, the range includes standard and valved options. The manifolds give easy access to install in service cupboards or accessible areas for ease of use. Additionally, the manifolds give extra flexibility meaning it can be installed under a bath for hot and cold feeds to baths, sinks, and showers.

The introduction further enhances the Wavin Tigris K5/M5 press-fit system of multilater composite pipe (MLCP) family. With a testing system, the Tigris K5/M5 has a range of benefits that make it the go-to product for plumbing installations involving drinking water, chilled water, heating systems, and underfloor heating systems. The Tigris K5/M5 is designed to prevent errors made during installation, resulting in a reliable and durable connection that has been tested beyond the requirements for a 50-year lifetime.

Pipelines have been historically tested using water pressure, a method that comes with great risk. The greatest being legionella, a water-borne bacteria that can cause a potentially fatal lung infection in those who breathe in infected water droplets. Evidence suggests that this bacteria could develop if pipes aren’t effectively dried after water-pressure testing. The on-going concern for those involved in building large-scale projects has led Wavin to help combat the issue. The Tigris K5 system uses air-pressure testing, which tests the pipes effectively without the risk of droplets developing bacteria.

The Tigris system also employs an 80-decibel pressure leak alert, which sounds a high-pitched whistle when a leak is detected – enough to be heard in the loudest environments. Designed by specialist engineers at Wavin, this is the world’s first acoustic leak alarm, setting the Tigris K5 firmly apart from any other systems on the market.

HEP20_SOTN_pic1 copy 2Leading push-fit plastic pipe brand, Hep2O, has launched State of the Nation 2020, with the research delivering some fascinating findings for the UK’s plumbers. Wavin, who manufacture Hep2O, scoured the country to understand what customers really think of plumbers and how the current pandemic has affected their trust in this essential trade. Overall plumbers get a thumbs up, with the majority of homeowners (a whopping 73 per cent) still happy to invest in plumbing work and to welcome plumbers into their homes.

HEP_SOTN_Infographic1 copyThe State of the Nation survey asked homeowners the questions that plumbers have always wanted to know, but were too afraid to ask, including would you leave a plumber alone in your house, do you attempt your own plumbing work and where do you find a new plumber?

The final results provide some useful insights into how plumbers should be working with their customers. Just over a third of people (35 per cent) prefer to find a plumber through recommendations from friends or family, meaning a good reputation and word of mouth is key. When it came to the most important factors homeowners look for in a plumber, cost and recommendation came out top, with just under half of respondents (49 and 48 per cent respectively) saying they were their top priority. The research also shows that if plumbers are planning on emailing their customers, then they shouldn’t! Most (57 per cent) want tradespeople to pick up the phone for a chat to talk about work. And when it comes to leaving plumbers alone in their home it seems that there’s a mutual trust, as 82 per cent said they would fully or somewhat trust them.

HEP_SOTN_Infographic2 copyNot only did the research provide some practical advice, it also shines a light on the brilliant work and talented tradespeople out there. 75 per cent of homeowners stated that they have always been happy with their plumbing work and haven’t needed to complain about a service.

Karen Stables, Marketing Manager at Wavin said: “We want to help installers by helping them to understand their customers even better. We know that plumbers are busy people so there’s rarely a chance for them to stop and take stock of the industry as a whole. In the current environment it’s more important than ever that tradespeople are able to maintain and grow their business, and this research will provide some key insights to help them improve their customer’s experience and win more jobs.”

HEP20_SOTN_pic2 copyThe survey is just the beginning for State of the Nation 2020. We also put the findings to key influencers in the plumbing community to find out what they really think. Our video series brings their thoughts to life, it really explores the different topics and looks at practical ways this information can be used. Some key themes emerged so we’re launching two masterclasses focusing on promoting your business and financial management tips, run by experts in these fields, which will be launched across our social channels in the coming weeks.

HEP_SOTN_Infographic3 copyHep2O couldn’t address the biggest topics of 2020 without mentioning COVID-19. During lockdown, additional research was carried out to find out how safe customers feel having tradespeople in their house, whether they view plumbers as keyworkers, and what safety measures they would expect plumbers to have in place throughout the pandemic.

A huge 75 per cent said they would want plumbers to abide by social distancing, 73 per cent would ask them to wear masks and 45 per cent would prefer if they wore gloves Even though the majority were happy to have plumbers in their homes at the moment, 27 per cent of customers still aren’t comfortable. Despite this, there is clear admiration for the trade as 82 per cent said they viewed plumbers as keyworkers throughout the pandemic.
