Hi Crab,
thks for ur reply! I am more assured and will take note ur point.
Oki, oh so ur trunking start frm both toilets then to the rooms....did you install any aircon for ur living room?
Ours will be system 3 for living room and bedrooms. We are hacking the wall btw MBR & bedroom 2, so will hv only one aircon unit there. Then 2 aircon units in bedroom 3 and living room.
