Precautions during installation of pipes
Do not use pipes made of materials that may cause rust in the water supply pipe. In general, VP pipes
or other materials specified by regulations for a 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 for a diameter of
or 1/100 for a diameter of
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 may cause scalds
or 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.
