Steps
- Look up plumbing code sizing and minimum slope rules for drain pipes.
- Build a sloped PVC drain on the adjustable frame with the pump feeding water from the bucket.
- Install the flow sensor and program the Arduino to log flow rate.
- Measure maximum flow capacity at 3 or more slopes and 2 pipe sizes.
- Compare measured capacity to the code-based sizing rules.
- Chart flow vs. slope and document the rig for your portfolio.
What to photograph for your portfolio
- Drainage rig
- flow vs slope data
- capacity validation
- slope verification
