Domestic Lead Purging System For Treating Stagnated Water
Domestic Lead Purging System For Treating Stagnated Water
US Patent:
5011598, Apr 30, 1991
Filed:
Feb 16, 1990
Appl. No.:
7/480791
Inventors:
Alan G. Nathanson - Dix Hills NY
International Classification:
E03B 704
US Classification:
210136
Abstract:
A system for removing lead from a stagnated domestic hot and cold water system having fixtures and faucets is disclosed. Cold water pipes containing cold water are connected to the fixtures. Hot water pipes containing hot water is also connected to the fixtures. Crossover pipes fluidly connect the cold water pipes to the hot water pipes so that the cold water can enter the hot water pipes. Check valves assure that the cold water enters the hot water pipes and not visa-versa. A pump circulates the cold water and the hot water through the cold and hot water pipes when the faucets are closed so that a circulation system without the need for a third water line to create the circulation system is formed from the cold water pipes through the hot water pipes and resulting in a reverse flow loop through the hot and cold water pipes. A purifier removes sediment and numerous other water contaminants from the stagnated domestic hot and cold water system, including lead which has been leached into the hot water by stagnation, without having to flush the stagnated domestic hot and cold water system. Thus, eliminating the wasteful dumping of the stagnated hot and cold water.
