TDR Venus RV Water Pressure Booster Pump 12V — 4 GPM, 50 psi, Self-Priming On-Demand

The TDR Venus 12V RV Water Pressure Booster Pump is a self-priming, on-demand freshwater pump delivering up to 4 GPM and approximately 50 psi to improve water flow for kitchens, bathrooms, decks and washdowns.

Designed for RVs, boats and other 12V systems, this compact electric booster pump brings steady pressure and automatic operation to mobile water setups. It runs on a 12V DC supply, offers a robust 170W motor, and includes plumbing-friendly fittings so you can replace or upgrade your existing pump without complex modifications. Built-in protection features and a fine inlet strainer help guard the diaphragm and extend service life when used with clean freshwater only.

How does this pump improve water pressure in an RV or boat?

The pump raises low municipal or tank-fed water pressure to a usable level for showers, sinks and spray hoses. It operates on demand, so it starts when a faucet is opened and stops when you close it, keeping water delivery consistent without manual controls.

• Delivers up to 4 gallons per minute (approx. 240 GPH) for steady flow.
• Rated near 50 psi peak pressure; typically around 45 psi under load.
• Automatic on-demand activation for simple, hands-free operation.
• Self-priming design reduces installation height constraints from tank to pump.

What plumbing and electrical connections are required?

Installation uses common marine/RV fittings and a 12V DC power source. The pump’s housing accepts 3/4" male inlet and outlet connections and includes a 1/2" adapter for flexible hookup options, making it compatible with many existing systems.

• 12V DC power — connects to vehicle or vessel battery systems.
• 3/4" male inlet/outlet with included 1/2" adapter for plumbing ease.
• Compact footprint for mounting in tight compartments or engine bays.
• Simple wiring: inline fuse recommended and standard battery cable sizes.

What maintenance and water quality limits should I follow?

The pump is intended for freshwater only; abrasive or corrosive liquids will damage internal diaphragms and valves. A 50-mesh inlet strainer is fitted to block debris, but routine checks and occasional cleaning will protect performance and lifespan.

• Use only clean, non-corrosive freshwater — no oily or chemical fluids.
• Inspect and clean the 50-mesh inlet strainer periodically.
• Avoid running dry for extended periods to prevent diaphragm wear.
• Follow basic winterization steps if exposed to freezing temperatures.

What warranty and support does TDR Venus provide?

TDR Venus supplies presale and after-sale support plus a limited 180-day warranty. If you encounter setup questions or performance concerns, the manufacturer recommends contacting their support team for troubleshooting and replacement guidance.

• 180 days limited warranty from date of purchase.
• Email or phone pre- and post-sale assistance available.
• Replacement parts and service guidance provided when applicable.

Who is this for: The TDR Venus 12V booster pump is suited to RV owners, liveaboard boaters, small marine craft and anyone needing a compact, reliable freshwater pressure solution on a 12V system. It’s ideal if you need automatic on-demand water delivery, straightforward plumbing compatibility, and a pump designed specifically for clean freshwater applications rather than industrial fluids.
