I have a 275 gallon water tank and need water pumped to the pressure washer.** A: Anything less then I believe its 55 pounds of pressure going to the pump and it turns on automatically. So if water comes out of your tank at a lower pressure the pump should sense it and turn on and pump water out at 55 lbs. **Q: Can this pump have bleach run through it without corroding?** A: Limit it to the 2-3ppm chlorine concentration of a city water supply. **Q: Will this work in a home that just has low pressure on top of the hill of the city to supply a house? Showers, sinks, toilets...** A: No **Q: What type of male threads are on the pump's outlets IT IS NOT NPT!!! are they GHT (Garden hose threads )? how to adapt them to USA NPT?** A: Comes with adapters and I hooked up to pex plumbing. I used pex pipe and crimps. You can buy adapters for pex or anything you need on Amazon just search for it. ## Frequently Bought Together - WASSERMANN Water Pressure Diaphragm Pump 115V AC 4.0 GPM 45PSI,Self-priming Booster Pump with Power Plug, for Kitchen Bathroom RV Marine, Yacht Garden - DERNORD PVC Tubing 3/8"ID X 1/2"OD Flexible Clear Vinyl Hose 10 Feet for Food Grade - Homebrewers Outpost - D1262 Pluto Beverage Gun - ABS --- ## 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/500084473-rv-water-pumps-fresh-water-pump-for-rv-kitchen-barthroom](https://www.desertcart.hr/products/500084473-rv-water-pumps-fresh-water-pump-for-rv-kitchen-barthroom) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-16*
