Many of us have heard it’s not a good idea to pour grease down a drain. However, most homeowners don’t know why this is bad. Nor do they know precisely what happens once the grease enters the drains and pipes.
So Why IS Pouring Grease Down a Drain Such a No-no?
Grease undergoes chemical alterations under temperature fluctuations. Grease also mixes with other debris and chemicals in the pipeline and sewers, and it can form a solid mass. This mass ends up blocking the pipes and making a mess in your kitchen. One study revealed that 47% of sewer backups in the U.S. occur due to grease buildup. Roughly half of our plumbing service work involves some form of blockage removal.
This Is Not a DIY Fix
When you pour grease down a drain, it travels through the pipes and begins breaking down into its molecular components—glycerol and fatty acids. These components bind with calcium deposits resting in the sewers to form a glob-like compound that clings inside the upper sides of the pipes when water levels rise. Plumbers even have an informal name for this glob— they call it a fatberg. Fatbergs, if left unattended, can get really large. One plumbing company in the UK, in fact, found a 17-ton fatberg in a sewer ceiling! The lesson here? Keep grease away from the drain. If you have an existing backup in your drain, don’t treat it using a store-bought drain cleaner. This temporary fix only pushes the fatbergs further into the sewers, creating a bigger problem down the line. Always call a professional.
