CRESTWAVE 1.0L Pre-Pressurized Accumulator Tank, 125 PSI, 1/2 MNPT – Reduces Pump Cycling for RVs, Boats, and Travel Trailers

Experience smoother water flow and quieter operation with the CRESTWAVE 1.0L Pre-Pressurized Accumulator Tank. Designed for RVs, boats, travel trailers, and caravans, this compact tank buffers pressure fluctuations, helping your water system feel more consistent during peak usage.

Key benefits stem from thoughtful design. The 1-liter internal volume acts as a small reservoir, absorbing surges when multiple taps or showers are used at once. The result can be less abrupt cycling of the water pump and, in turn, reduced noise and wear over time. The unit is pre-charged to 10 PSI at the factory and handles up to 125 PSI, with a 1/2" MNPT inlet/outlet for broad compatibility. To maintain safety, do not inflate beyond the bladder’s limits and do not over-pressurize the system.

Compact, versatile, and RV-ready

Despite its larger capacity compared to some compact tanks, CrestWave keeps a practical footprint: roughly 12 inches by 5 inches by 4.49 inches. This makes it suitable for tight compartments in RVs, boats, caravans, and other pressurized water systems where smooth operation matters. The universal 1/2" MNPT ports are compatible with many pumps on the market, supporting a straightforward install across a range of mobile settings.

What you gain in everyday use

• Buffering action reduces sharp pressure spikes during peak water use
• Lower pump noise and less frequent cycling for a calmer water experience
• Protects the freshwater system from pressure shocks, potentially extending pump life
• Quieter operation without sacrificing water delivery in RVs, boats, or caravans

• Internal Volume: 1 L; Pre-Charge: 10 PSI; Operating range 10–125 PSI; Max pressure: 125 PSI
• Inlet/Outlet: 1/2" MNPT; Dimensions: 12" x 5" x 4.49"; Suitable for most pumps
• Usage note: Follow factory pre-charge and avoid over-inflation to protect the bladder
• Why choose CrestWave: more capacity than standard 0.75 L tanks for improved stability

Whether you are on the road or at sea, CrestWave’s accumulator tank is designed to complement a range of water systems, offering smoother pressure and a more predictable water experience. Real-world results will depend on your setup, but this unit is built to support quieter, more reliable operation over time.
