Correcting a Drainage Pipe with the Wrong Fall
Silver Drains & Plumbing recently repaired a section of drainage pipe after identifying an incorrect pipe gradient that was preventing wastewater from flowing properly.
Because the pipe wasn't installed with sufficient fall, grease and debris were settling inside the drain instead of being carried away. Over time, this caused recurring blockages and occasional backflow throughout the drainage system.
By correcting the affected section, wastewater can now flow as intended, improving drainage performance and helping prevent future blockages.
Why Pipe Gradient Matters
One of the most important parts of any drainage system is something most homeowners never see—the pipe's gradient, also known as its fall.
Drainage pipes rely entirely on gravity. If they're too flat, wastewater slows down and solids are left behind. If they're too steep, the water can rush away too quickly, leaving heavier waste stranded inside the pipe.
A correctly graded pipe allows both water and waste to travel together, helping keep the drain clean every time it's used.
Why Grease Becomes a Bigger Problem
Kitchen grease is already one of the leading causes of blocked drains, but poor pipe gradient makes the problem much worse.
When wastewater slows inside the pipe, grease has more time to cool and stick to the pipe walls. Over time, that sticky layer traps food scraps, soap residue and other debris, gradually reducing the pipe's diameter until blockages begin occurring more frequently.
Correcting the gradient removes the underlying cause rather than simply clearing the symptoms.
Signs Your Drainage Pipe May Have an Incorrect Fall
A drainage problem caused by poor gradient often develops slowly.
Some common warning signs include:
-
Frequent blocked drains
-
Recurring kitchen sink blockages
-
Slow drainage despite repeated clearing
-
Wastewater backing up during heavy use
-
Gurgling noises in nearby fixtures
-
Drains that block again shortly after being cleared
If blockages continue returning despite professional cleaning, the pipe itself may need to be assessed.
