FAQ

Altopoly® is a high-quality, non-metallic barrier pipe system available in both PB (polybutylene) and PEX (cross-linked polyethylene) variants. It offers a flexible, corrosion-resistant, and cost-effective alternative to traditional copper plumbing systems, with easy push-fit installation.

Altopoly PB and PEX pipes are ideal for domestic hot and cold water systems, including potable water installations. Their flexibility and durability make them perfect for both new builds and retrofit projects.

Altopoly fittings are designed for secure, permanent connections. While they can be disconnected in some cases, they are not intended for reuse. For best results and to maintain system integrity, always use a new fitting when making changes.

For best performance and to maintain the 25-year guarantee, Altopoly fittings should be used exclusively with Altopoly PB or PEX pipes.

Radiator panels are usually made of mild steel, a material prone to corrosion. In the absence of air this reaction forms a black magnetite sludge, which is ferrous so can be captured by a magnet. The new Magblu incorporates an industry leading 12000 gauss magnet – simply put, a higher strength magnet means more sludge removal.
​MAGBLU 22MM MAGNETIC BOILER CLEANER​​​

If no magnetic filter is fitted the magnetite particles will circulate and be trapped in the boiler system, most likely in the circulator pump where they will cause premature wear.

It really couldn’t be much simpler, all the valves and connections are included and there is a step by step installation video available online. Servicing is very easy, and regular cleaning is a simple 2-minute job.
​MAGBLU INSTALLATION INSTRUCTION VIDEO​​​

There is a handy access point on the Magblu where the system water can be analysed and inhibitors or cleansers can be added. With an active magnetic filter installed, the system will run more efficiently, saving energy & water consumption.
ULTRA CONCENTRATE FLUSH CLEANSER

​ULTRA CONCENTRATE INHIBITOR​​​

To clean a central heating system in accordance with BS7593:2019, MAGBLU 500ml Ultra Concentrate Flush Cleanser should be circulated with all valves open for a minimum period of one hour before flushing. For badly contaminated systems a longer circulation period may be necessary. Warming the system will aid the process. After cleansing, the system should be drained and thoroughly flushed through all drain points with clean water. Refill and treat with MAGBLU 500ml Ultra Concentrate Inhibitor.

NavYseal PTFE Cord is a high-performance sealing solution designed to replace traditional PTFE tape. It is a thicker, string-like material made of over 200 fibres, offering superior sealing strength and reliability. Unlike standard PTFE tape, NavYseal contains wetting agents that give it adhesive properties, allowing it to bond effectively to metallic surfaces. This ensures a more secure, leak-resistant seal – especially in demanding or directional joint applications.

- Fully WRAS Approved for use with potable water systems
- CE EN 751-2 & BS 6920 certified
- High tensile strength and sealing efficiency
- Adhesive properties for better grip on metal surfaces
- Wide temperature range (-55°C to +180°C)
- Handy dispenser with built-in cutter
- Trade counter display box available

NavYseal PTFE Cord is suitable for sealing threaded joints in:
- Hot and cold water systems
- Potable water lines
- Gas installations

Unlike flat PTFE tape, NavYseal is a thicker, fibrous cord that wraps securely around threads. It is easier to apply, especially in joints that require directional tightening, and its adhesive properties ensure a more reliable seal.

MB Pressfit fittings are designed for use in domestic and commercial potable water systems. They offer a fast, flame-free installation method using a press tool, making them ideal for safe and efficient plumbing work.

Salvus® Pressfit fittings are specifically designed for gas installations. They provide a secure, tamper-proof connection without the need for soldering or open flames, reducing fire risk and installation time.

Navigator has made it simple and safe to identify fittings at a glance:

• MB Pressfit water fittings feature a blue identification ring and black O-rings.
• Salvus® gas fittings feature a yellow identification ring and yellow O-rings.

The coloured rings provide instant visual confirmation of the fitting type. Once pressed, the ring drops off - helping installers spot unpressed joints and confirm secure connections. The O-ring colour further reinforces correct application during installation.

This dual-colour system helps prevent mix-ups, improves safety, and speeds up installation on-site.

Yes - both MB Pressfit (for water) and Salvus® (for gas) fittings are fully certified and compatible with standard UK press tools:

• ✅ Press System Compatibility:
  Both ranges are designed for use with M profile press jaws, including Rothenberger pressfit guns, ensuring fast and secure flame-free installation.
• ✅ Certifications:
  
  • MB Pressfit: WRAS approved and independently tested to BS EN 1254-7:2021
  • Salvus® Gas: BSI approved with Kitemark KM 768668, also tested to BS EN 1254-7:2021
• ✅ Design Life:
  Both systems are engineered for a 30-year design life, offering long-term reliability and peace of mind.

These features make Navigator’s pressfit ranges a trusted choice for professional installers working on water and gas systems.

RADMAG has been designed to fit inside the vertical column of most standard towel warmer & designer radiators. However, in some cases the gap inside the column may be restricted because the horizontal rails protrude into the vertical column, or there may be a sealing ring restricting the diameter where the top nut sits. If you are unsure, please check there are no blockages by inserting a length of dowel or garden hose, before trying to force the RADMAG into place.
If the internal gap is compromised, the RADMAG diameter can be reduced by removing the orange caps. There are 2 spare washers provided with the RADMAG simply unscrew the orange spacers and replace with the rubber washers for an easier fit. See https://youtu.be/jMcaDQ0Tz6M
If the fit is still too tight, RADMAG can be used without washers or caps, but we recommend that RADMAG is then not extended fully to ensure that the magnet does not come into contact with the radiator itself.

Everything in the Salvus® range has been designed and manufactured to the highest possible specifications and is independently tested and certified to the latest UK and European standards. All of our manufacturing facilities operate to ISO 9001:2015 and are regularly audited by and verified by independent certification bodies, including BSI and DVGW. The Salvus® range includes Kitemark approved Cooker Hoses in various lengths and with a variety of end fittings, Kitemark approved Cater Hoses and Couplers, PTFE gas seal tape and a complete range of Press Fit fittings.
