Aquatec CDP 8800 water booster pump + Transformer 115V 1/4 & 3/8

Pressure switch is not included in this listing. Pressure switch need to be purchase separately. Depending on your applications at what cut-off pressure setting. This listing is for pump and transformer only. You can turn on/off manually, or use (optional) pressure switch or (optional) timer to turn on/off the pump. This pump is to increase input pressure to a RO system. This pump is not for increasing pressure to ice maker or refrigerator. That's different model. For ice maker pump or increasing output pump, please get Aquatec 5851 0.7GPM to 1 GPM pump This is Aquatec Boost pump and transformer for Reverse Osmosis Water systems. The input/output of the pump is 3/8" quick connect fitting, we also include two reducer fitting to 1/4" if you have 1/4" tubing. So this setup will work for both 3/8" and 1/4" OD tubing. If you are using this for a RO system you may need to order separately a pressure switch and/or a solenoid valve. If you are buying this pump for misting application. Please note that the pump need to be placed at floor level, the pump need to be lower than the water level. It can self prime but input tubing need to be all the way near the bottom of the container and be tied down/ tether with heavy object so the tubing can stay near the bottom and not floating up. The number of nozzles the pump can support depends on the flow rate of the total nozzles and the pressure you want to achieve. Connect one nozzle first and make sure everything works then add more nozzles and check pressure. With less nozzles the pump is able to high pressure above 80 psi. As you add more nozzles, the pressure decreases.
