Waterway Plastics 519-3150 Vacuum Plate - 90 Degree

What This Part Is Used For
The Waterway Plastics 218-1890A Gunite Air Pipe Measuring Tool is used to measure and set correct air pipe depth in gunite spa and pool installations. It ensures that air lines are positioned accurately before gunite is applied. This tool helps maintain proper air injection performance once the system is operational. Builders use it during rough-in to avoid airflow restrictions. Accurate placement is critical for consistent jet aeration.

Why This Part Matters
Incorrect air pipe depth can reduce jet performance or introduce unwanted turbulence. Once gunite is applied, correcting pipe placement is extremely difficult. This measuring tool helps eliminate guesswork during installation. It ensures consistent results across multiple jets and air lines. Proper measurement prevents long-term performance complaints and rework.
