http://www.tongdapvcpipe.com/html/What-water-supply-pipe-diameter-should-be-selected-for-four-levels-building-1344.html
Size: from 20mm to 800mm

Pressure: 0.6Mpa~2.5Mpa

Advantages of PVC-M water supply pipe:

1.    Compare to PVC-U, PVC-M has excellent quality of tenacity and shock resistance.

2.    High resistance to water hammer, avoid destroy during the operation.

3.    High resistance to the impact of external forces. Avoid the crazing during the transportation and installation.

PP-R PIPES Advantages:

1. Sanitization & Non-poison: This product is green building material which is able to use for pure clean drinking water pipe system. No heavy metal additives would not be covered with dirt or contaminated by bacterium.

2. High Temperature Resistance: the maximum sustained working temperature is up to 70 Degrees Celsius, the maximum transient temperature is up to 95 Degrees Celsius.

3. Corrosion-Proof & Non-Fouling: Resist chemical matters or electron chemical corrosion. Able to avoid the pipe's fouling or blocking as well as the blemish, rust on basin and bath.

4. Heat Preservation & Energy-Saving: Excellent heat insulation features, minimal thermal conductivity which is only 0.5% of the conductivity of metal pipes.

5. Less Weight & High Strength: Its proportion is only 1/8th of metal pipe's, with pressure-proof strength up to over 5MPa(50kg/sqcm),high tenacity and impact resistance.

6. Beautiful Appearance & Higher Flow Capacity: Smooth inner and outer surfaces, less flowing resistance, soft color and beautiful figure.

7. Easy and Reliable Installation: Using heat melting joint without sleeve wire, and taking few seconds for connecting and adopting good quality copper inserts to connect the metal pipe and basin.

8. Long Using Life: The pipe system can be used for over 50 years under normal condition.    

9. PP-R is recyclable and environmental friendly.

For maximum convenience: use 12 centimeter pipe from the tank to the top floor (level). 

6 centimeter pipe from a tee to the top level bath room. 8 centimeter pipe from the tee to the 3d level bathroom. 4 centimeter pipe from the 3d level tee to the third level bathroom. 6 centimeter pipe between the 3d level tee and the 2nd level tee. 4 centimeter pipe from the 2nd level tee to the 2nd level bathroom. 3 centimeter pipe from 2nd level tee to the the first level tee, etc. You need to decrease the pipe size as you go down as the pressure is increasing, otherwise using water in the first level bathroom will drastically cut the pressure available to the higher bathrooms.
