Pro Tip: Be considerate and realize when other tradesmen will be installing around your work. For everything up to 3” pipe, the grade must be set to ¼” per foot and 4″ pipe must be set to 1/8 “ per foot. One very important thing in the plumbing trades are the following words: drainage MUST grade. Once all that has been done, I get up into the attic to connect the appropriate vents and then terminate them to outside air through the use of a roof increaser. If you weren’t already using a Hole Hawg style drill, you will really want one at this stage. Usually what I do upstairs is pop all my vents up into the ceiling. Now it’s time to drill out the holes for drainage and venting. Typically a 4-1/2″ hole saw does the trick when drilling out for a toilet drain.
You then have to verify and then duplicate this. With that being said, there are times that the home builder you are working with will spec a specific measurement. Then, if the fixture is directly off the tub, I’ll measure 15-inches off that. If the finishes have not been chosen, I will usually measure 13-inches off the back wall. Then you can check the manufacturer’s shop drawings to make sure you drill your hole in the proper location. Pro Tip: It’s important to know what kind of toilet is being installed for the plumbing rough-in. I’m sure every plumber has their own system but what I like to do is once the tub/shower is in place is to mark and drill out the water closet holes (toilet holes for y’all in the US). Believe me when I say that if you come across a joist under the toilet, there will be a few choice words exiting your mouth that may or may not be directed towards the individuals that framed the house. Once you cut the holes, you can bring the tub back, re-level it, and set it with at least 2″ screws. However, if there is a joist on the center of a shower drain, then it’s time to call back the framers to do their job properly! But not before you check the rest of the house for framing issues.
If you happen to be over a floor joist on the tub drain, all you need to do is to offset your waste and overflow beside the joist. Your boss won’t be happy about a back charge bill for a new joist to be put in. Pro Tip: Before you drill that hole, check to make sure you’re not directly over a joist.

Cordless tools are more expensive thanks to the batteries, but I haven’t had to use my generator in over a year now. In the last year however, I have decided to make the move to cordless for all my tools in order to leave the generator in the van to collect dust, to cut down on the amount of time a job takes me, and to never have another corded tool unplug itself when I get to the top of a ladder because it got caught on something on the way up. Breaks to run out for gas or other items you don’t have on-site take time – and time is money. Pro Tip: If you have to use a generator, be sure you have enough fuel for the day. If not, you’ll pull our the generator and get her cranked up. If you have it, you’ll roll out the extension cords you need to cover your area. The first thing you do on any new job is check for power. Hey, we’re in Canada, not Central Florida like Clint DeBoer and Kenny Koehler.
The first thing we do is curse the cold weather, as nobody likes being cold. Typically my apprentice and I get to the site bright and early in the morning.
