Product Description
How it works？
1. The accumulator tank stores a volume of water (0.75L) under pressure.
2. When the water system is in use, the stored pressurized water is released, maintaining the desired pressure and reducing the frequency at which the pump needs to activate.
Why you need this RV Water Pump and Accumulator Tank System?
1. Reduces Pump Cycling
2. Maintains Consistent Water Pressure
3. Improves Energy Efficiency
4. Reduces Noises
5. Eliminates noise caused by pipe vibration
Where to use this pump set?
It can be widely used in RVs, boats/yachts, water purification systems, and other liquid transfer applications.
What should I do if there is a water leak?
A leak is often caused by the connector loosening during transportation. Check for loose fittings. Loosen slightly, realign threads, and tighten both sides evenly. For hose leaks, wrap teflon tape on threads before connecting for a better seal.
What should I do if the product doesn’t work after installation?
Check the wiring on the back of the unit. Loose connections may cause power failure. Make sure all wires are securely connected.
TIPS 
【Features】This set consists of a 5 chamber diaphragm pump 70 PSI with 7 GPM water flow, and a 1L pre-pressurized accumulator tank, 2 hose adapters. A fully assembled pressure set that simplifies the installation of water pressure systems for both the professional and amateur installer
【Quiet Operation】Equipped with anti-vibration rubber feet and shock-proof iron plate, this set can reduce noise of your water system, operating volume below 45 DB. It can also reduce water pump kicking on, provide a more quiet and pleasant environment, especially in residential or recreational settings like RVs and boats
【Smooth Water Flow】Kohree 5-chamber RV Water Diaphragm Pump provides high volume water flow to 7 GPM. And the accumulator tank acts as a buffer, providing a steady water pressure even when the demand fluctuates, ensuring smoother water flow for a consistent user experience. It also prevents surges or drops in pressure that can be potentially damaging to fixtures and appliances
【Extended Pump Lifespan】By reducing pump cycling, the system minimizes wear and tear on both the pump and other components, leading to fewer maintenance issues and longer service intervals
【Run Dry & Thermal Overload Protection】Kohree RV Water Pump can run dry for a short period time, reducing the risk of motor burnout. The thermal overload protection function of the motor makes our products safer and can be used longer
