Suction Line Cavitation

Cavitation happens when the pump cannot get enough water on the suction side. Air bubbles form and collapse, damaging the pump internally.

What you’ll usually notice

You may notice: – grinding or “marble” noise – vibration – overheating

What’s normally behind it

This usually happens when the suction setup is restrictive. Typical causes include: – undersized suction pipe – blocked intake – long or poorly designed suction runs

Why quick fixes don’t stick

Installing a larger pump makes cavitation worse.

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 improving suction conditions so the pump receives proper flow.

What you can check yourself

You can check a few things yourself:
– reduce flow and see if noise decreases
– inspect strainers for blockage

When to call someone in

If cavitation is present, the pump will be damaged quickly and should be corrected immediately.

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.
