I used one to replace the check valve in my door drain in my walk-in tub which would only have at worst a 3 -4 inches of standing water in the tube and It allowed the water to pass. **Q: Will this work if tubing is laid sideways?** A: Yes it will work in any position. **Q: Where do I put this on a portable a/c condensation line. Close to the unit or down the line further. It will be on a 10 ft clear flexible tubing?** A: If you using a condensate pump put it as close to the pump as you can. If you not using a pump and using gravity draining you don't need it. **Q: Can this be used on a submersible 600gph water pump for the basement?** A: Check valves of this size are meant for use in smaller capacity pumps such as condensate pumps for air conditioners or dehumidifiers. Not for basement pumps. --- ## 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.dk/products/216534139-quickun-3-8-barb-hose-one-way-inline-check-valve](https://www.desertcart.dk/products/216534139-quickun-3-8-barb-hose-one-way-inline-check-valve) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-07-28*
