??Please Noted  1. Because the maximum output power of OMMO water pump is 36w, so there will be a sound, a little lower than 12V/5A (60w) about 60-70 dB. If you don't like this sound, we suggested that a box for the diaphragm pump to isolate it, and the other four corners  should be fixed so that the sound will be reduced. 2. The diaphragm pump can only be used to pump water, CANNOT pump air, oil, or flammable liquid. 3. Our pumps are 100% factory tested, so there will be water pouring out, so don't worry we promise it was new.  ?What can OMMO Fresh Water Pump Do  OMMO small pressure diaphragm pump can home use for Garden sprinklers, lawn, shower, water taps in the boat, caravan, RV or motor home suits for Caravan, Camper, RV, Boats, Marine, Home Garden, and Camping ?Specification: Power: 36 W Voltage: DC12V Max Current: 3A Max Flow: 2.9 LPM Max Pressure: 85PSI Vertical Suction: 3.9ft Dimension: 2.6×3×7inch Weight: 680g Temperature Range: 0~60°C /32~140°F ?Package Include : 1 ×Water pump 2 x Hose Clamps 1 ×User manual ?If you have any problems, please feel free to contact us.
