OVERVIEW
What it is
Modified PVC is PVC blended with an impact modifier during manufacture. That makes it tougher and more ductile than uPVC, so it resists knocks, pressure surges and cracking. It is dark blue, so it's easy to tell apart from uPVC on site. Designed for a service life of 50 years.
WHY SPECIFY IT
- TougherBetter resistance to impact, rough handling and rocky trenches.
- Lighter to handleAbout 30% lighter than uPVC from Class 9 up: a 110 mm Class 9 pipe weighs 8.0 kg against 11.4 kg.
- More flowA thinner wall gives a slightly larger bore for the same outside diameter.
- Surge-resistantCopes better with the pressure surges of pump starts and valve closures.

HANDLING AND INSTALLATION
Good practice on site
General guidance for storing and laying mPVC pipe. Always follow the project specification and the relevant installation standard.
- Support pipes evenly along their full length when stacked; keep stacks low and on a flat surface.
- Alternate sockets when stacking so they don't carry the load, and protect pipe ends.
- Don't drop pipes onto hard surfaces or drag them. Lift and place them.
- Limit storage in direct sunlight, and keep sockets and their rubber seals clean.
- Lubricate the spigot and push it fully home into the next socket.
- PVC is less impact-resistant in cold weather, so handle it with extra care on cold mornings.
- Lay pipe on bedding free of stones and follow the engineer's specification for bedding and backfill.
Which class do I need?
Pick a class above the highest working pressure in your line, including pump pressure and surge. Class is the working pressure in bar at 20 °C: Class 6 is rated to 6 bar, about 60 m of head. Tell us the pump and the run and we'll recommend one.
uPVC or mPVC?
Both are certified pressure pipe. mPVC is tougher and lighter for the same class; uPVC is the proven standard and the only one of the two made in Class 4. If your trench is rocky or the pipe will be handled roughly, choose mPVC.
How long are the pipes?
uPVC, mPVC and sewer pipe: 6 m effective length up to 315 mm, and 5.8 m from 355 to 500 mm. Effective length is measured up to the socket, so it's the length each pipe adds to your line. SWV comes in 6 m lengths and conduit in 4 m lengths.
How do I tell the pipes apart?
uPVC is light blue, mPVC is dark blue, sewer pipe is cream, SWV is white, and HDPE and LDPE are black. Every certified length is also batch-stamped with its material, class, size and standard.
How long does it last?
uPVC and mPVC pressure pipe are designed for a service life of 50 years.
