“The drainage detail that can kill a pool project: if your lot's drainage pattern doesn't naturally flow away from the pool equipment pad, you'll have water intrusion in the equipment vault during LA's rain season. We engineer proper pool deck drainage on every project. It adds $1,500–3,000 and prevents $15–30K in equipment replacement.”
Ask specifically about the pool's plumbing layout: Flex PVC vs. rigid PVC. Flex PVC is easier to install and is frequently used by lower-tier contractors. Rigid PVC is the correct material for underground pool plumbing — it doesn't collapse over time, doesn't degrade from chlorine exposure, and is easier to diagnose for leaks. Specify rigid PVC below grade.
