TMV & BACKFLOW
SERVICES
Compliance matters.
Safety comes first.
TMV and backflow services help protect people, properties and the water supply.
Thermostatic Mixing Valves help control hot water temperatures, reducing the risk of scalding in settings where safety is critical. Backflow prevention devices help stop contaminated water from flowing back into the drinking water supply.
At Wagtail Plumbing, we approach TMV and backflow work carefully, with a focus on safety, compliance, clear reporting and practical advice.

- TMV testing and servicing
- Tempering valve checks
