The drains in the cafeteria are clogged with oil over time; how should they be cleared?
Thread Content
The sewers in the cafeteria are often clogged by oil that is poured in directly. What chemicals should be used to clean and unblock them? Additionally, issues such as pipe corrosion need to be taken into account. Any experienced experts who can offer advice would be appreciated; thanks
The oil used in the cafeteria should be animal fat, mainly lard and beef tallow. If the pipe is not long, clean it with hot water and a small amount of detergent; make sure the water is hot enough. If the pipe is very long, a cleaning device is needed.
The pipe in our cafeteria is quite thick; it’s filled with oil that has accumulated over the years. I’m not sure how much detergent would be needed to clean it. haha. We have sodium hypochlorite available right now – I wonder if it can be used to clear the pipe Experts, please give some advice. Thanks for the explanation from above
I’m not sure how thick your oil layer is. If it’s very thick, simple chemical cleaning may not be very effective, as it’s difficult for the chemicals to penetrate such a thick layer. In such cases, mechanical cleaning might be an option; however, it’s unclear whether there’s enough space for that to be done. If it proves too difficult, it would be better to install a new pipeline – it’s better to avoid spending time, money, and effort on something that might not work

A few days ago, I really couldn’t find a better way to solve the problem; so I had someone use fire water to flush the pipes, and a lot of substances that resembled charcoal fragments came out. I wonder how these impurities were formed – they are quite large and come in pieces. Please advise me.

It’s probably because the food has fermented inside! ! ! Next time, install a grille at the inlet of the sewage pipe in your cafeteria
