-[{{:​living_in_new_zealand:​country_calendar:​backdraught.jpg ​ |Back-draught shutter (see the self tapper on the left)}}]I mentioned earlier that the on-suites can be cold. I had also found on cold windy (Southern winds) nights our lounge struggled to keep warm, but never worked it out. The reason was a howling gale coming back through the extraction fan vent above the showers. I found out when changing the lamp on the vent when the wind was blowing, I had never noticed before, when in the shower the extractor is on and when not using the shower, the cubicle door is closed and I never felt the draught. The solution is easy, an inline back-draught shutter (they can be called by other names). Non of the usual suspects seemed to stock them or under stood what I was talking about. I ordered two from plumbing ​World and was charged $60 each!!!. I should have checked the price before ordering, believe me you can them cheaper. The shutter I got was for putting in line with the flaps horizontal, that was no good for me, and have fitted them directly onto the extract vent above the shower. One problem was, one vent flipped open to far and would not close, so a small mod. as in the photo. A self tapper is fitted above the hinge to restrict the flaps to 90 degrees, this solves the issue and you get a satisfying two clunks from the flaps closing when switching off the fan.+[{{:​living_in_new_zealand:​country_calendar:​backdraught.jpg ​ |Back-draught shutter (see the self tapper on the left)}}]I mentioned earlier that the on-suites can be cold.
