Why MDPE? Some MDPE properties

When many other plastics and polymer products opt for PVC type materials - why do manufacturers make water pipe black MDPE?

Well, it's all to do with the properties of the polymer that make the black pipe. It's less dense than harder plastics - which means it's more forgiving when used for gas/water under the ground.

When installing black pipes under the ground, you have to be mindful of the pressure that will be put on them when the earth is compacted - with a product like UPVC, pressure across a length could lead to a fracture if the run is sitting on an irregularity in the bed beneath it. This is generally referred to a 'notching' a small but hard obstruction (usually gravel) that means there's a huge amount of very localised pressure on the run.

With a hard plastic, pressure like this will cause the pipe to crack - and a cracked  water pipe is going to cause the property owner a headache. MDPE water piping on the other hand is less dense and less brittle - so the notch won't cause a problem - nor will the flow of the water be compromised.

In the past, copper was used - owing to it's similar properties - but with MDPE being so much more cost-effective, it makes sense to use it in the place of expensive metal pipework.

As well as being an effective way of distributing mains water, MDPE pipe is also much easier to repair than many alternatives. Although access can be time-consuming, when you're at the pipe, simply cutting with hand tools a section out and connecting a new section with compression fittings can be done quickly and easily.
