摘要： The invention relates to a flushing method in a tap water pipe system, comprising pipes for hot (3) and cold (2) water, connected to tap points (8, 26) to dispense hot and/or cold water. Flushing is carried out by applying a pressure change in the water pipe system or part of it. Then the hot and cold water pipes (2, 3) are short circuited at the tap points to allow flow from the one to the other pipe. Flushing is carried out first at the one pressure level and then at a higher pressure level to activate additional tap points (26). During flushing and post-rinsing, the pressure within the one pipe (3) is lower then the pressure within the other pipe (2). In this way hot water from the boiler (7) can flow first through the cold water pipe (2) and then through the hot water pipe (3) and then back to the boiler (7) to kill bacteria causing Legionnaire's disease, without water consumption.

摘要： With respect to, made of a copper alloy, such as bronze or brass, having undergone, for example, nickel-containing plating, a city water valve, water or hot water supply valve, pipe joint, strainer, faucet metal fitting, pump supply item, water meter, water cleaner, water or hot water supplier and other liquid-contact equipment items, for prevention of nickel leaching even when brought into contact with fluid such as city water, there are provided a method of preventing nickel leaching from copper alloy made liquid-contact equipment items, protective film forming agent for nickel leaching prevention and cleaner for nickel leaching prevention. In particular, there is provided a method of preventing nickel leaching from copper alloy made liquid-contact equipment items, comprising applying a protective film forming agent containing at least one member selected from among benzotriazole, benzotriazole derivatives and organic acids such as linear chain fatty acids to at least a liquid-contact surface of copper alloy made liquid-contact equipment items to thereby form a protective film by which nickel leaching is suppressed.

摘要： The invention relates to a processing method for processing an interior of a pipeline system (1), said pipeline system (1) comprising a partial system (2, 21, 22) between a first connection (3, 31, 32) and a second connection (4, 41, 42), wherein the processing method comprises the following processing steps: preparing a first working medium (5, 51, 52, 53) under positive pressure (P
+ , P
+1 , P
+2 , P
+3 ) relative to an ambient pressure (P
0 ). Preparing a second working medium (6, 61, 62, 63) under negative pressure (P
- , P
-1 , P
-2 , P
-3 ) relative to the ambient pressure (P
0 ). The partial system (2, 21, 22) between the first connection (3, 31, 32) and the second connection (4, 41, 42) is thereby acted upon simultaneously by the first working medium (5, 51, 52, 53) under positive pressure (P
+ , P
+1 , P
+2 , P
+3 ) and the second working medium (6, 61, 62, 63) under negative pressure (P
- , P
-1 , P
-2 , P
-3 ), such that a fluid flow (7) of the first working medium (5, 51, 52, 53) under positive pressure (P
+ , P
+1 , P
+2 , P
+3 ), through the partial system (2, 21, 22), to the second working medium (6, 61, 62) under negative pressure (P
- , P
-1 , P
-2 , P
-3 ) is generated in one direction between the first connection (3, 31, 32) of the partial system (2, 21, 22) and the second connection (4, 41, 42) of the partial system (2, 21, 22). According to the invention, the direction of the fluid flow (7) through the partial system (2, 21, 22) between the first connection (3, 31, 32) and the second connection (4, 41, 42) is reversed at least once in at least one processing step. The invention further relates to a subdistributor (81) for performing the method according to the invention, and a processing device comprising a subdistributor (81) according to the invention.

摘要： A processing method for preventing elution of lead in a lead-containing copper alloy for preventing elution of lead from faucet metals, etc., made of a lead-containing copper alloy, and a city water service fitting made of a lead-containing copper alloy for preventing elution of lead. Elution of lead remaining in a limited amount on the surface of a lead-containing copper alloy material can be prevented by forming a chromate film on this surface. The city water service fitting made of the lead-containing copper alloy is immersed in an alkaline etching solution in a pre-processing step of a nickel chromium plating step to selectively remove lead on the surface of the lead-containing copper alloy material and is then activated in a solution such as sulfuric acid and hydrochloric acid. Nickel plating is subsequently effected, and then chromium plating is effected in a sargent chromium or chromium fluoride bath, and a chromate film can be formed by immersing the city water service fitting in a chromate solution.
