What does PVC mean?

It stands for Plastic Vinyl Chloride, this is a common thermoplastic resin that is extruded into pipe and many other products.

What is MPVC?

MPVC stands for - modified  Plastic Vinyl Chloride

What is UPVC?

UPVC stands for -  Unplasticised Poly Vinyl Chloride.

What is the difference between UPVC and MPVC?

MPVC was designed so that the integral working pressure of the pipe would not be effected, but would save on material costs as using this technology the wall thickness could be made smaller thus saving on material, but meeting all specifications

Can I use MPVC in my water Bore?

No – the Mpvc pipe is manufactured with a lot smaller wall thickness than UPVC so it’s collapse pressure is to low, to withstand the ground or grouting pressure. Many Councils and water authorities have banned this pipe from being used in bores.

What sizes does PVC come in?

12mm to 450PVC. There are many sizes in between but  some sizes are not of standard and will only be manufactured to sufficient quantities

What classes does PVC get manufactured in?

PVC pipe is made in many different wall thicknesses and this is stated as “Class”. So there is Class 4.5 this is the thinnest, Class 6, Class 9, Class 12 and Class18 The highest pressure pipe

My bore has hot water can I still use PVC bore casing?

Pvc pipe can handle temperatures up to 60 deg C, but at this temperature the pressure it can handle is deteriorated. At 20 deg c the rating is standard.

Can I use HDPE as bore casing as it is cheaper?

The main reason for not using poly pipe as bore casing is the density of the pipe is lighter than water, therefore it floats, there has been occasions when the driller comes back to the bore hole after fitting HDPE and found the casing is out of the ground and reaching for the sky, therefore it is very rarely used as Bore casing, PVC is a better choice where possible.

What is the life of PVC?

In the right conditions 100 years can be expected, but if in the direct sunlight then it will deteriorate a lot quicker.
