Float Valve Adjustment
Adjusting the float valve to set the correct fill level and shut-off.
An overflowing cold water or feed tank wastes water and can cause damp and damage if left. Tell us what's happening and where you're located, and we'll help you request assistance from a local plumbing professional to repair the fault.

Share a few details and we'll help direct your request to a participating local professional. Submitting an enquiry is free and carries no obligation.
Not every overflowing water tanks problem looks the same. These are the signs that suggest it's worth requesting professional help.
Water continuously running out of the overflow pipe outside your home.
Damp patches or green staining on the wall below the overflow outlet.
The water level in the tank rising higher than it should before shutting off.
A hissing or vibrating noise from the tank as the valve fails to close properly.
Visible cracks, splits or dampness on the tank itself.

A symptom is rarely the whole story. Whether it's a visible fault or a problem hidden behind a wall, under a floor or inside a fitting, understanding the likely cause first helps ensure the right overflowing water tanks work is carried out — and reduces the chance of it coming back.
The right approach depends on the problem. A professional can advise what's appropriate for your situation — not every professional offers every method below.
