The pipe needs to be the proper size to handle what it''s carrying (water, gas, air, drainage, etc.), but it also cannot be too small, or it could cause the volume to travel too fast. And that could cause serious issues, such as water hammer (a hydraulic shock or pressure surge), which in turn could damage the pipe system and the fixtures attached to the piping.

16/10/2012· Whilst having an extension done, the pluer has moved the mains water stop valve. Someone has mentioned my pipe size is only 15mm and should be 22mm. Don''t confuse water pressure with flow rate. It may be that your street/area suffers from low pressure.

But, on average, a 1/2” distribution pipe is only good for about 3 fixture units, while a 3/4” pipe is rated at approximately 10 fixture units. The hot water fixture rating of a bathroom is 1.5 fixture units, and a kitchen with sink and dishwasher adds 1.9 fixture units That’s 3.4 already, and we haven’t even added a laundry at 1.8 fixture units.

Existing buildings, and buildings that are not connected to mains water, may have low pressure systems or unequal pressure systems (with different pressures for hot and cold water supply). As an example of the difference in water Chinage, a low pressure hot water system shower flow may average about 7 litres per minute, while a mains pressure shower may average around 12–20 litres per minute.

You will need to refer to the pipe sizing chart (Figure 16.1) available in Chapter 16 of the Rheem Hot Water Manual. The chart will give you recommended pipe diameter for copper pipe. Calculate the equivalent pipe size using Table 1.1 in AS/NZS 3500.1 if you are using a different pipe material.
