After typing all this out, one more thought. On 2021-06-22 by Julie Umecker. A booster pump (Goulds v6P) in a 3.5-story building is cycling on and off frequently and pressure fluctuating between 64 PSI at rest and up to 68-70. We are no aware of any out of the ordinary call for water. And cycling is on going all day and night. With iSave you get pressure exchanger, booster pump and motor integrated into one compact unit for high efficiency and short pay-back time. The small footprint of iSave makes it a popular solution when the space is limited. When fitted with iSave, the Danfoss APP pumps produce more fresh water per square meter than any other system in the market. The adjustment is done with a very small Allen wrench — 050" to be exact. The factory preset is normally 80 psi for the pump and 40 psi for the pressure switch. These settings will run home RO units perfectly and allow a smooth shutoff of the pump when a good, strong tank pressure is reached. There is great wisdom in leaving the settings alone. zQj5OfD.
