NEVER drill a hole within 1′ of the end of any beam or a floor joist. You should also avoid drilling within 1′ of where a beam sits on top of a support column or post. Only drill within the 1/3 middle of the span horizontally and the 1/3 middle vertically.
Can I drill through a structural beam?
Can I drill through a structural beam? Holes can be drilled through the neutral axis without loss of ‘bending’ strength.

How much of a joist can be cut out?

What is the minimum fall for a waste pipe?
The most important bit of obvious advice ever: soil and waste pipes need to be on a downhill gradient! The “fall” or “drop” should be between 1/40 (1cm down for every 40cm across) and 1/110. Too steep (1/10) then the water runs quicker than the solids so doesn’t wash them away (ugh!).

What’s the start of a toilet waste system?
The start of a toilet waste system is the toilet’s own waste outlet, while the main pipe is the soil stack. The stack is a 3-inch or 4-inch length of vertical pipe that drops to the sewer and is connected to a 2-inch pipe that rises through the roof to provide venting.
