This Blue PVC Inspection Port is installed directly inline on the vertical stack. It features a side access cover that can be unscrewed. The cover contains a rubber ring inside. When tightened during normal use, it stays watertight and odor‑free. When a blockage occurs, simply unscrew the cover to reach in or insert a drain snake. Both ends are standard sockets for solvent cement joints, making on‑site installation quick and straightforward. Available in four sizes from 50mm to 160mm, suitable for residential stacks and industrial drainage systems alike.
Product Advantages
1. The side access cover can be unscrewed at any time, allowing blocked pipes to be cleared without cutting the pipe section, reducing long‑term maintenance costs.
2. The threaded cover has a built‑in rubber sealing ring. Once tightened, it provides reliable sealing with no leakage or odor under normal drainage conditions.
3. Anti‑slip ribs on the outer wall of the cover allow it to be unscrewed by hand or with basic tools, making inspection quick and easy.
4. Injection‑molded from 100% virgin PVC‑U material, resistant to acid, alkali and corrosion, anti‑aging, suitable for domestic sewage and rainwater drainage applications.
5. Straight‑through flow channel with no internal protrusions, ensuring unobstructed drainage flow and reducing waste buildup on the wall.
6. Uniform blue color matching the same series of blue PVC drainage pipes and fittings, convenient for project identification and coordination.
Installation Tips
1. Cut the pipe end square and flat, remove burrs, wipe clean, then apply solvent cement.
2. Face the access cover outward. Do not install it against a wall, or it will be impossible to unscrew later.
3. Apply cement to the socket, push the pipe all the way in, and hold for a few seconds until the cement begins to set before letting go.
4. Must be installed on the bottom floor and top floor where sanitary fixtures are located of the vertical stack. Intermediate floors should be set at code‑specified intervals.
5. After all installation is complete, tighten the cover first, then run water to test for leaks.
Selection Reminders
Select according to the pipe outer diameter. Match the inspection port size to the pipe size.
For gravity drainage only. Do not use on pressure water supply pipes.
Reserve operating space at the installation location. Do not bury it in a wall or block it with cabinetry.
For large‑diameter stacks above 110mm, it is recommended to face the access cover toward a corridor or access panel side.
Stack in a cool, shaded warehouse. Avoid outdoor sun exposure, as prolonged UV exposure makes PVC brittle.
The cover and body can be stacked separately, but keep the rubber ring away from oil and avoid crushing or deforming it.
Keep away from heat sources such as boilers and heating pipes.
FAQ
Q: Are inspection ports and cleanouts the same thing?
A: No. An inspection port is installed on a vertical stack with a side opening. A cleanout is installed at the end of a horizontal pipe or on the floor, usually facing upward. Their usage and installation locations are different and they cannot be used interchangeably.
Q: Should I wrap Teflon tape on the cover?
A: No. The rubber ring inside provides the seal when tightened. Wrapping Teflon tape may cause uneven compression and lead to leakage.
Q: Can this be installed on a horizontal pipe?
A: Not recommended. This product is designed for vertical stacks. For horizontal pipe inspection, use a horizontal pipe cleanout or floor cleanout.
Q: Can the cover be completely removed?
A: Yes, it can be fully unscrewed, making it easy to see inside the pipe and insert a drain snake.
