🚫 Wrong Job – Neatly Done but Functionally Incorrect
Looking at this structure, it’s clear that while the pipework is neatly arranged for aesthetic appeal, functionality has been compromised.
We can observe two different window openings:
The smaller one is typically for the Restroom/WC ventilation.
The larger one is for the Kitchen ventilation.
Now, someone commented:
> “Yes. It's designed to be covered with panels, look at the wall differentials.”
Here’s my response to that:
> No Sir! It was not designed to be covered with anything. If panels were installed, they would automatically block the ventilation windows as well. Therefore, it can only remain as surface piping — nothing more. Thank you, Sir.
🔧 My Technical Observation as an Engineer/Plumber
Using a single 4" waste pipe to handle both Restroom and Kitchen discharge is a major design flaw.
Here’s why:
It will frequently block, because kitchen waste (grease, food particles) and toilet waste (solid waste, paper) have very different flow characteristics.
When combined, they create build-up and clogging issues, especially in multi-storey systems.
The correct approach:
Provide two separate 4" waste stacks — one for the Restroom and another for the Kitchen.
This allows independent flow and minimizes blockage risk.
Moreover, with two separate lines, you can easily frame and conceal the pipes with a panel (as suggested in the earlier comment) without obstructing ventilation openings.
That’s how I’d handle this job for both functionality and aesthetics.
