You would need a 1/2"FNPT to 3/4" Pex Fitting **Q: could this pump, pump water up 6 feet** A: Yes, this pump will both pull and push water up 6 feet. **Q: Why will my pump make noise but not pump water. It has been dry for 5 days of travel. Now we are parked and it’s not working.** A: 2 possible problems come to mind. The pump is self priming, as long as there is water in the tank getting to the pump it should work. There is a possibility that it was installed the wrong way, there is an intake opening and an output opening. Check that, it could be the problem. The pump could also be defective if there is water getting to it and it is installed correctly but still not working... ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well *by M***K on 29 October 2025* Great pump ### ⭐⭐⭐⭐⭐ Review *by E***N on 17 November 2025* キャンパーの給水システムに使用。 以前つけていたDCポンプに比べて、力もあるし静音性も良い！ 一年近く使用しているが、耐久性に問題なし。 ### ⭐⭐⭐⭐⭐ Review *by É***S on 5 August 2025* great pump super quiet , holds pressure now , my old one was loud and ran every 5 mins , super happy now ## Frequently Bought Together - SEAFLO Water Diaphragm Self Priming Pump 3.0 Gallons/min (11.3 Lpm) 45 PSI New Rv/Marine 12 Volt Dc / 12 V Demand Fresh - ML7-12 - 12 VOLT 7.2 AH SLA BATTERY - Mighty Max Battery brand product, black --- ## 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.hr/products/543190028-seaflo-12v-2-8-gpm-45-psi-water-pressure-pump](https://www.desertcart.hr/products/543190028-seaflo-12v-2-8-gpm-45-psi-water-pressure-pump) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-18*
