● Install the drain pipe with downward slope (1/50 to1/100) and so there are no rises or traps in the pipe.
● Use general hard polyvinyl chloride pipe (ø3/4 [I.D.] ; ø1-1/16 [O.D.]) and connect it with adhesive (polyvinyl
chloride) so that there is no leakage.
● Install pipe supports on long lines.
● Do not install air vents on the drain lines.
● Always insulate the drain pipe to prevent condensation.
