Detailed Checklist
Videos
- Short overview, doesn't say much but gets you into the inspector mood - [1]
- Relatively comprehensive video, with tub-shower pre-plumbed so none of its drain detail is shown:
Notes
- DWV - 5 psi air or water. See that valve holds. 0.1 psi graded valve.
- How do you stop the bath tub overflow? Drain should close, but overflow
- Each trap protected by vent
- See cleanout requirements.
- Ford Fitting for water supply line if supply line connection is inside the house.
- 125 Water pressure test required
- Vacuum breakers on hose outlets
- Supply water line fill is inspected prior to covering
- Approved grounding system for water supply line?
- Tracer wire for water supply from meter to foundation
- Toilet clearance 15" from sides and 12" from back
- Nail plates for vent pipe - if you have sheathing above vents.
- Tape for joints in vents must be UL 181 listed. [2]
- Exterior wall water lines must be freeze protected. [3]
- Max 32" between PEX line supports. [4]
Tub
- If tub is preinstalled, how to close overflow? The over flow I capped off by making a plate to screw on and used a piece of mouse pad as a gasket. [5]
- If tub is on second floor, its overflow can be the high water mark, so there is no need to close it. This would not apply if testing with air.
- For rough-in, the easiest approach to tub in our case (it doesn't fit through doors, so must be pre-located. Pre-located does not mean it has to be pre-plumbed. So leave the drain kit off - just make sure it is possible to install it _after_ the trap is installed.
- Assumes that trap doesn't have to be in for rough plumbing. [6]
Sequencing
- Water Heater - Since it is a fixture [7] - a water heater is installed in the finish phase [8]
- Water heater is often installed at rough plumbing phase [9]
