Backflow & TMV Testing Sydney

Flowline Plumbing and Gas expert Backflow and TMV Testing

Backflow is when your water flows backwards against the regular flow. This can be hazardous when it contains harmful substances. Flowline Plumbing and Gas are experienced in installing, testing, repairing, and providing certification of Backflow prevention devices within your residence or commercial building.

Thermostatic mixing valves (TMV) blend hot water with cold water. Constant safe shower and bath outlet temperatures are controlled with a TMV. This mixing valve prevents burns from hot water. It’s critical that water is at a safe temperature in both commercial and residential buildings to prevent burns. In some industries installation and yearly certification of thermostatic mixing valves is a compliance requirement.
