Abstract: A method for treating a domestic supply water circuit, that comprises injecting a treatment product comprising silicates into the water flowing in said circuit in order to form a film on the inner surfaces of said circuit, characterised in that the injection of the treatment product comprises at least one step of injecting silicates at a concentration of between 100 and 200,000 milligrams per litre (mg/L) into the water flowing in said circuit for a period of between 10 minutes (min) and 24 hours (h), the flow rate of water flowing in the circuit being controlled within a range of between 0.05 and 100 litres per minute (L/min) and the temperature of water flowing in the circuit being controlled within a range of between 40 and 65° C.
