Easy to set up and pulls water from rear of van easily to tap inside ### ⭐⭐⭐⭐ Great little pump with back-pressure shutoff *by on Reviewed in the United Kingdom 13 October 2025* Do not tighten mounting screws too tight as this will result in vibration/noise ## Frequently Bought Together - Seaflo 12V 1.2 GPM 35 PSI Water Pressure Diaphragm Pump - Water Pump Strainer, 3/8 Inch Hose Barb In-Line Strainer Twist-On Sprayer Filter for Water Pump 12V DC 80 PSI RV Camper Marine Boat Lawn - 3/8" ID x 25 Ft High Pressure Braided Clear PVC Vinyl Tubing Flexible Vinyl Tube, Heavy Duty Reinforced Vinyl Hose Tubing, BPA Free and Non Toxic --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/111198576-seaflo-12v-4-3-lpm-water-system-pump](https://www.desertcart.vn/products/111198576-seaflo-12v-4-3-lpm-water-system-pump) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-09-15*
