I want to install a toilet in our poolhouse. We will have easy access
to the main sewer line when the concrete surrounding the existing pool
is removed in advance of the new pool being built. I need to add a Y
to the main line (1978 cast iron) but am not sure how to cut it. I
want to add PVC for the new line. Can this be done? A water supply is
already available. I plan on installing the Y 36 inches below the
surface and running the PVC piping over a layer of rock fill. We have
plenty of rise (4 feet) over a distance of 50 feet. The pool house is
well ventilated (4 foot lattice walls). Do I need an exhaust stack?
Thanks for any help.
You should check local codes but to answer your questions, Lennox makes a
saw blade for a recip saw that will walk right though the old cast iron
(6tpi I think). Then you connect it back with PVC using burial rated
I would have a vent extending above the roofline of the structure regardless
of codes.I can't imagine any code that would not require this.
