Water Supply Industry Interpretations and Advice
- Area of Interest : Backflow prevention
- Topic : Fluid category
- Title : Dishwashing machines in small nursing homes
- Clause Reference : Schedule 2 paragraph 15 & G15.3
- Reference Number : B17
- Decision Date : February 2002
In small nursing homes and other similar establishments, subject to a risk assessment based on local circumstances, a lower category of backflow protection than the usual fluid category 5 for healthcare premises can be accepted for dishwashing machines. The risk assessment should show that the need of the residents for healthcare does not result in a risk of contamination by backflow which is unacceptable for a lesser level of protection.
