About this item

• Ultimate Water System Combo, Better Together! – CrestWave 12V RV Water Pump & 1L Accumulator Tank work seamlessly to provide consistent, high-pressure water flow while reducing noise, cycling, and wear on your pump. While a pump alone can cause frequent cycling, pressure drops, and noise, the pre-pressurized accumulator tank acts as a buffer, smoothing out water flow and reducing pump strain. This duo extends pump lifespan, minimizes energy use, and delivers a more stable and quiet water system—making it far superior to buying just a pump or tank alone

• Powerful & Reliable Water Flow Anytime, Anywhere – Featuring a 5-chamber diaphragm pump with up to 7 GPM water flow and 70 PSI auto-shut-off pressure, this combo ensures a smooth and uninterrupted water supply—whether you’re showering, washing dishes, or cleaning gear in your RV, boat, or off-grid cabin. The 1L accumulator tank prevents surges and pressure drops, delivering steady water pressure for an optimal experience in any setting

• Whisper-Quiet & Vibration-Free for a Peaceful Journey – Unlike standalone pumps that frequently cycle and create noise, this system is equipped with an accumulator tank, anti-vibration rubber feet, and a shock-proof iron plate, reducing noise to ≤45dB. Enjoy a quieter, more relaxing adventure whether you’re parked at a scenic campsite or anchored in a peaceful bay

• Built for Extreme Adventures & Long-Term Use – Designed for rugged outdoor conditions, this system features a 35% thicker copper motor, NSK dual ball bearings, and an IP68 waterproof rating. The pump self-primes up to 10 ft, lift up to 125 feet and handles extreme temperatures (41-140℉), ensuring durability for RV road trips, boat excursions, and off-grid living

• Smart Protection & Easy Installation – The run-dry protection, thermal overload prevention, and over-pressure safeguards keep your system running safely. The accumulator tank reduces stress on the pump, lowering energy consumption and extending maintenance intervals. With multiple fittings (1/2" MNPT + 1/2" barbed adapters) and flexible mounting options, installation is quick and effortless for RVs, boats, travel trailers, and remote cabins

• Reminder: This accumulator tank is pre-charged to 10 PSI at the factory. No adjustment needed — install and use directly
