Why standing water matters
When water sits unused in pipework and outlets it can lose the protective effect of regular movement and temperature changes. In certain conditions this can increase the risk from bacteria such as Legionella which is why water hygiene is a formal duty for landlords and holiday let owners.
Holiday lets often have periods of vacancy followed by intensive use. That pattern makes it important to think about what happens to the water system between guests, especially if parts of the property rarely see use.
Temperature and time
Bacteria associated with poor water hygiene tend to thrive in certain temperature ranges. Modern, insulated buildings and part heated properties can sit in that range for longer. Understanding how your own system behaves over time is part of a formal risk assessment.
A simple flushing routine between periods of low use
Many owners choose to include a basic flushing routine as part of vacancy or pre arrival checks. The details and frequency should be based on your own risk assessment and advice from a competent person, but a typical pattern might include:
- Running all cold taps and mixers for a short period to draw fresh water through.
- Running hot taps long enough to confirm that stored hot water reaches an appropriate temperature.
- Running showers so that standing water is cleared from the hose and head.
- Flushing each toilet to refresh cistern water and spot any filling issues early.
- Checking and where appropriate draining or flushing outside taps, long hose runs and rarely used outlets.
Practical note
Always think about spray and mist from showers when flushing. Some operators choose to run shower heads gently into a container to reduce aerosols and then follow the specific advice from their water hygiene provider.
How this links to wider compliance
A flushing routine is only one part of water hygiene. Owners also need to think about stored hot water temperatures, dead legs, little used wings of the property and any higher risk features identified in a Legionella risk assessment.
My role is not to provide specialist water hygiene consultancy. Instead I build agreed routines such as flushing checks into regular visits and into your wider Holiday Let Compliance Audit. That way water hygiene is logged alongside gas, electrical and fire precautions rather than sitting in isolation.
