Precautions during installation of pipes
Do not use pipes made of materials that may introduce rust for the water supply pipe.
In general, VP pipes or other materials specified by regulations in that particular region, are recommended for installation.
In general, Type L deoxidized copper pipes are recommended for hot water pipes.
In general, the same diameter and same pressure is recommended for hot water pipes and water supply pipes.
Always use a reamer to deburr the ends of cut pipes.
Avoid using inverted U-shaped pipes (siphon) as these can cause air to become trapped.
Always connect hot water pipes and water supply pipes after removing all contaminants such as dirt, sand and oil as
these can cause problems.
After connecting the pipes and testing water flow, clean the filter and shower head.
Ensure that the drain pipe is installed at a gradient of 1/50 or more for a diameter of ∅75 or less, or 1/100 or more for
a diameter of ∅75 or more.
Do not connect the hot water pipes and water supply pipes in reverse.
Connecting pipes in reverse will mean the temperature of water cannot be controlled properly by the water taps, which can
cause problems including burns.
Ensure that the hot water pipes from water boilers are only run over a short distance so as to minimize resistance.
Longer pipes can cause fluctuations in temperature and poor hot water delivery.
Always wrap pipes with lagging material after installation is complete.
