Below are some precautions to prevent water leaks and/or resin spillage. 1. Municipal water pressure often increases significantly at night when there is little water usage. This can put excessive strain on DI tanks and connecting hoses. The DI systems are not intended for water pressure to exceed 80 psi. If possible, shutting off the water supply to DI tanks at night is a good safeguard to prevent water leaks. 2. It is also highly recommended that a pressure regulator (set below 80psi) is installed prior to the DI tank system. Pressure regulators are prone to failure and need to be maintained on a frequent basis. 3. It is a good idea to have a floor drain and wall protectors installed in the same room as the DI tanks. 4. If the tanks will be exposed to freezing conditions or feed water above 120 F then this can likely lead to water leaks. 5. If any vacuum occurs in the DI system, then the DI tanks will likely rupture and leak. A vacuum breaker should be installed prior to the DI tanks to be safe. Some examples of when a vacuum may occur are when DI tanks are elevated from their point of use, a fire hydrant was exercised on the street or the DI water is re -pressurized after the Dltanks. 6. When a softener is used before a water heater, the pop off relief valve should be in working order on the water heater. 7. If the DI water is going to a storage tank, the float level switches need frequent maintenance to prevent overfilling. 8. There should always be a post -filter placed after DI tanks in the event of a lateral failure inside the tank which will cause resin to leak into the water supply. A post filter (5-micron pore size) will capture any lose resin beads and prevent any further contamination. 9. If possible, placing the DI tanks outside is another safeguard to prevent water damage from leaks. 10. Water backflow into the inlet of the DI tank will cause resin leakage from the inlet of the tank. A note on leak detectors: Leak detectors are not reliable, and you should not rely on them as a foolproof method to prevent water related damages. Furthermore, if the leak occurs after the DI tanks, then the deionized water often doesn't activate the leak detector since deionized water is not very conductive.
