Question 1

What is the Thomsun 90mm x 4m PN-20 PPR Pipe used for?

Accepted Answer

This is a seamless PPR-C pipe designed for potable water supply, hot water distribution, irrigation, and general plumbing. It supports hot and cold water up to 95°C and is rated PN-20 for robust pressure handling.

Question 2

What are the main specifications of this pipe?

Accepted Answer

Diameter: 90 mm; Length: 4 m; Material: PPR-C; Pressure rating: PN-20 (20 bar); Temperature rating: up to 95°C; Seamless/homogeneous design; Resistant to corrosion and chemicals; Lightweight and easy to install.

Question 3

How do I install this PPR pipe with fittings?

Accepted Answer

Use compatible PN-20 PPR fittings. Cut the pipe square, remove burrs, and dry-fit with the fittings. Use the recommended heat-fusion (socket fusion) method to join the pipe and fittings, then hold and cool as per tool guidance to ensure a leak-free joint.

Question 4

What does PN-20 mean for this pipe?

Accepted Answer

PN-20 indicates a nominal pressure rating of 20 bars at 20°C. It describes the maximum safe operating pressure for the pipe size under standard conditions.

Question 5

Why choose PPR-C pipes like Thomsun over traditional metal pipes?

Accepted Answer

PPR-C pipes offer superior corrosion and chemical resistance, are lighter, have seamless joints that reduce leak risk, are typically easier and faster to install, and can provide long-term cost savings due to low maintenance.

Question 6

What applications is this pipe best suited for?

Accepted Answer

Ideal for domestic water supply, hot water distribution, irrigation, and general plumbing where potable water is involved. It’s suitable for indoor and outdoor use, provided direct sun exposure is managed to protect the pipe.

Question 7

How does the 90 mm diameter compare with a 110 mm version in terms of performance?

Accepted Answer

Both are PN-20 PPR pipes, but the 110 mm version will generally deliver lower pressure losses for larger flow, while the 90 mm version is more compact and easier to install in tighter spaces. Both are compatible with PN-20 fittings but choose diameter based on system flow requirements.

Question 8

How does the 90 mm x 4 m PN-20 PPR Pipe compare to a 75 mm x 4 m PN-20 PPR Pipe?

Accepted Answer

The 90 mm pipe handles higher flow with potentially lower pressure drop at the same system demand, while the 75 mm pipe is suitable for smaller flow requirements or tighter spaces. Both share the PN-20 rating and PPR-C material, but choose diameter based on your planned water demand.

Question 9

How does the 90 mm x 4 m PN-20 PPR Pipe compare to a 63 mm version?

Accepted Answer

The 63 mm version supports smaller flow; it’s easier to fit in compact installations. The 90 mm pipe provides significantly higher capacity for steady higher flows. Both are PN-20 and PPR-C, so the choice depends on required throughput and pipe routing.

Question 10

Are there safety or compatibility considerations I should be aware of?

Accepted Answer

Yes. Use potable-water-safe materials, avoid direct prolonged sunlight exposure (protect outdoor installations from UV), follow local codes, wear appropriate PPE when cutting, and ensure all components (pipe, fittings) share the same PN-20 rating and are from compatible PPR systems for a secure joint.

Question 11

What maintenance is required for this piping?

Accepted Answer

PPR pipes require minimal maintenance: periodically inspect joints for leaks, flush the system to remove debris, and avoid exposing the pipe to conditions outside its rated temperature and pressure. Damaged sections should be replaced with compatible PN-20 PPR components.

Question 12

Which fittings should I use with this pipe, and where can I find them?

Accepted Answer

Use PN-20 PPR fittings designed for hot and cold water. For best performance and reliability, pair this pipe with matching Thomsun PN-20 PPR fittings available on Fepy. Example compatible options include Thomsun 110mm x 4m PN-20 PPR Pipe, Thomsun 75mm x 4m PN-20 PPR Pipe, and Thomsun 63mm x 4m PN-20 PPR Pipe, all available on Fepy with product pages:
