It's a new BTO so this pipe is actually at the top, with the water tank heater. Olden kind heater usually have 3 pipes but mine is the newer kind. Don't need this drain out pipe. The bottom part at the 2nd pic goes to the floor. Very near the drain in the toilet area.

I would like to ask, did anyone with new BTO that have the drain off pipe between the hot and cold pipe for heater, use it for aircon condenser water instead? I wanna have less trunking in the toilet and that drain off pipe seems so redundant and not put in good use. It seems so much better since the pipe is conceal and it goes down all the way to the drain nicely. If anyone did any like this, please share with me.

Hi can I check how did u do ur aircon with the drain off?
