Hi, I am thinking of replacing my current System 3 (10 year old) with a StarMex/Daikin System 3/4. I wish to have an outlet with higher output for my master bedroom if feasible. I am unsure if I can reused my exisiting pipes which run behind a custom wardroom. If I have to change the pipes, how much will it cost to dismantle and reassemble the wardrobe?
