My brother just bought a 10-year old house in Newmarket, Ontario,
Canada. I was just over 'inspecting' the house when we came across
this magical switch. The previous owner said to turn it on several
times a year. Yeah, ok. No reason, just do it.
Anyways, like the subject says, it turns on the upstairs bathroom fan.
Is this code for new construction? Is it just a quick way to vent
some smelly cooking?
Also, the builders dropped a 4-inch sewage line down the center of the
basement. It's a big sticking point when it comes to finishing the
basement...so they want me to divert it to another line. What sort of
slope does a big pipe like that require? Also, can I use T's or would
a more gradual union be preferred?
Finally, there is a standard switch that turns off the furnace, but
it's located right beside the furnace. Shouldn't it be located on the
wall/ceiling as you enter the basement?
