If you’re using copper or push-fit plumbing pipe, there can be doubts which stop you from making the change to Multipipe Multi-Layer Composite Pipe (MLCP). We’re here to help bust some popular myths and maybe give you a reason to make the change to a modern piping solution. 

1. MLCP is expensive 

MLCP pipe is actually cheaper than copper! You may find the fittings more expensive than copper – but you’ll use far fewer of them and be able to complete your installation much faster, which means you can get onto the next job quicker. Therefore, you’ll save money on the job overall.

Don’t forget that MLCP isn’t susceptible to theft like copper is as there is no re-sale value in it! 

2. Plastic is bad for the environment 

Undoubtedly, we’re all aware of the damage single-use plastics can do to the environment, however Multipipe MLCP is designed with a lifespan of at least 50 years. Additionally, MLCP will outlast its copper counterparts if used correctly, because it is less susceptible to corrosion and pinhole leaks that can occur with a harsh water system.  

The mining, refinement and transformation required to produce copper into end products (such as pipe) is a high energy process, using a great deal of non-renewable energy. What’s more, the flexibility properties of MLCP means that fewer fittings are required. 

When considering transportation, manufacturing and disposal, MLCP is a lower embedded carbon product than copper pipe, significantly reducing environmental impact. 

3. MLCP can’t be connected to Copper 

Another common complaint you might hear about plastic pipe is that it can’t be used in conjunction with copper systems. This is not the case. We have a huge range of adaptors that allow you to plumb MCLP systems and copper systems together. 

Some connectors can be pressed onto copper pipes, allowing you to connect MLCP systems to brazed copper piping. Similarly, there are threaded adaptors that will enable plastic pipes to integrate seamlessly with compression fittings.

4. MLCP doesn’t last as long as Copper 

First introduced to the UK market in the 1970’s, MLCP has consistently gained traction as a popular solution for flexible plumbing projects.

Multipipe has been supplying high-quality MLCP for both domestic and commercial projects for 20+ years. However, our MLCP is designed with a lifespan of at least 50 years and is WRAS approved with a 25-year guarantee.

5. You can’t bury MLCP in walls 

Multipipe MLCP is the perfect solution for modern renovations where homeowners want a sleek finish. Not only does the aluminium layer prevent any oxygen ingress, but it also means that the pipes can be found with a standard pipe detector when buried in walls. In addition, as our MLCP is flexible, it can often be installed without tearing out the entire wall and is ideal for tight spaces and retrofit projects.  

6. Plastic pipe can leach chemicals 

It’s easy to think that because chemical compounds form the basis of many plastics, chemicals automatically transfer to your water. But those chemical compounds are polymers and are not only inert; they don’t leach. So MLCP is the best choice to avoid corrosion, scale buildup, metallic leaching and damage from hard water.

What’s more, MLCP’s durability makes it suitable for various water types, including well water, water with high salt content and highly chlorinated water. The reality is you’re far more likely to see ‘blue’ water with copper piping than you are to experience issues with MLPC. Multipipe MLCP has a low heat expansion and is, therefore, suitable for heating systems too.  

7. You can’t use MLCP for drinking water 

Media reports regarding the dangers of BPA in water bottles should not be a reason not to use MLCP for water pipes. Plastic pipes don’t contain BPA, are made of different materials, and go through an entirely different process for manufacturing and testing.

In addition, Multipipe MLCP has WRAS approval which means it must pass a taste and odour test in order to be approved. 

8. There’s no real difference between PEX and MLCP  

MLCP enjoys all the benefits that a metal pipe system offers, plus all the benefits that modern materials like Polyethylene can offer. Featuring an aluminium core and polyethene exterior, MLCP is extremely strong and 100% oxygen diffusion tight. Whereas PEX-a pipe has a high expansion rate often looking unsightly and causing noises, but also the barrier is never 100% proof and can ingress air into the system.

What’s more, MLCP’s form stable design coupled with the solution’s flexibility, ensures that a minimal number of joints are required. We recommend using this solution for “behind the wall” applications, ideal for use with manifold plumbing schemes. 

Finally, don’t forget that, unlike push-fit external sealing joints, MLCP fittings seal inside the pipe where they can’t get damaged and compromise the joint.  

So, there you have it, eight popular myths surrounding MLCP debunked!
