To fix a noisy tap, check the aerator at the tip of the spout for mineral buildup, inspect and replace worn washers, or ensure the supply valves under the sink are fully open to prevent water restriction.
How to Stop a Kitchen Tap That is Making a Noise?
Yes, you can use WD-40 to help loosen a stiff tap, but it is meant for breaking down rust and grime, not for long-term lubrication. Because it is a solvent, it can wash away existing lubricants and degrade rubber parts over time.
A tap that makes a loud noise (like banging, squealing, or humming) when turned on is typically caused by vibrations in the water supply. This is usually due to a worn-out rubber washer inside the tap mechanism, an air pocket in the pipes, or excessively high water pressure.
Lubricate all moving parts: Use a high-quality silicone plumber's grease (not petroleum jelly or WD-40, which can damage rubber). Apply a thin film to all rubber O-rings, seals, and the valve stem where it turns.
A faucet making noise when you turn it on is usually caused by water vibrating against a restriction in your pipes, trapped air, or worn-out internal parts. The sound (whistling, squealing, or banging) typically pinpoints exactly what needs to be fixed.
To get rid of trapped air in your water pipes—which causes sputtering faucets, gurgling sounds, and reduced water flow—you need to "bleed" your plumbing system. You can do this by draining the entire system and systematically pushing the air out using your home's water pressure.
You do not always need a plumber to fix a water hammer. Minor, localized hammering near appliances or fixtures can often be resolved with simple DIY fixes, such as draining your home's plumbing system or attaching in-line water hammer arrestors.
A faucet that sounds like a machine gun is almost always caused by a vibration in the water supply. This rapid rattling or chattering sound is typically triggered by a worn-out internal washer, trapped air in the pipes, or water pressure that is too high.
Spraying WD-40 Multi-Use Formula up a faucet—specifically on hard-to-turn knobs, valve stems, and diverter spouts—is a common plumbing trick used to loosen mineral buildup, eliminate squeaking, and protect internal metal parts from rust and corrosion.
Loosening a tight or stiff water tap usually comes down to breaking through limescale, rust, or debris. Before you begin, always turn off the water supply to the tap to avoid accidents.
The best lubricant for faucet handles and internal cartridges is a 100% silicone-based plumber's grease. It is waterproof, safe for rubber or plastic O-rings, and won't contaminate drinking water. Never use petroleum-based lubricants like Vaseline, which will degrade and destroy rubber seals over time.

Simple Fixes for Noisy Faucets
If your tap is making a loud banging or clanking sound right after you turn it off, it is almost certainly a plumbing issue called water hammer (hydraulic shock). If it sounds more like a squeak, squeal, or vibration right as you close the valve, it usually means the rubber washer inside the tap is worn out or loose.
In plumbing, the "135-degree rule" is a code standard that dictates how much a horizontal drain pipe can bend or change direction. It limits the total cumulative angle of pipe fittings before a system requires an access point (cleanout) or must be vented, ensuring proper flow and preventing chronic clogs.
Yes, trapped air in water pipes can sometimes work its way out naturally over time through your plumbing fixtures. However, relying on this method can be slow and may cause frustrating sputtering, weak water pressure, and disruptive banging noises.
Generally, no, it is not a good idea to pour boiling water down the drain. While it can sometimes clear minor soap or grease clogs, the extreme heat can soften PVC plastic pipes, warp joints, damage rubber seals, and even crack porcelain sinks.

Yes, excessive water pressure can create a humming or vibrating sound in pipes. Over time, it can also strain your plumbing system, leading to leaks or pipe damage.
Pro Tip: When working with rusted and stuck components on plumbing parts, use WD-40® Specialist® Penetrant to bust rust and free up parts and hardware to move as they should. Our penetrant formula leaves behind a light lubricant and protective coating to ensure the rust stays away when you're done.
No, you cannot use WD-40 instead of plumber's grease.
A faucet handle that is hard to turn is usually caused by mineral buildup (limescale) from hard water, dry or failing internal parts (like O-rings or the cartridge), or a tightened packing nut. These issues create excess friction, making the handle stiff or sticky.
Plumber's lubricant (also known as plumber's grease) is a thick, waterproof silicone-based grease used to lubricate and protect moving parts in plumbing systems. It prevents friction, stops squeaks, and extends the lifespan of rubber or plastic components without degrading them.
