Noisy Check-Valve (Water Hammer Slam)

When water slams back against a valve, it creates a shockwave that stresses the system and damages fittings.

What you’ll usually notice

You may notice: – loud bang when pump stops – vibration in pipework – repeated noise cycles

What’s normally behind it

This usually happens due to poor valve positioning or failure. Typical causes include: – valve too far from pump – failed spring mechanism – lack of pressure damping

Why quick fixes don’t stick

Insulating pipes reduces noise but not the impact.

How this is normally handled

Water Usage Monitoring & Metering

This service diagnoses the real cause and fixes the system properly, not just the symptom.

What actually fixes it

This problem is normally handled by correcting valve placement and adding damping or soft-closing components.

What you can check yourself

You can check a few things yourself:
– identify where noise is loudest
– note timing with pump shutdown

When to call someone in

If the system is hammering, structural damage will follow if not corrected.

Why does my borehole water look dirty or sandy?

Dirty or sandy borehole water usually indicates poor borehole development, pump placement issues, or the need for proper sediment and media filtration.

Why do filters block so quickly?

Filters blocking quickly is often due to incorrect filter selection, unexpected water quality issues, high sediment loads, or lack of staged pre-filtration.

Why is my water pressure low?

Low water pressure is usually caused by undersized pumps, incorrect pressure settings, pipe restrictions, or supply limitations from municipal, borehole, or tank-fed systems.

Why does my pump keep switching on and off?

Rapid pump cycling is typically caused by pressure tank issues, incorrect pressure switch settings, leaks, or pumps that are oversized for the system demand.

When should I call a water system professional?

You should call a professional when problems repeat, systems behave unpredictably, pumps fail regularly, or when you need clarity before making costly system changes.
