The height is just scaled down but roughly 22" to reduce the overall volume. Thanks **Q: What sizes are the threaded connections? It looks like theres 3 blue ones and one red one? Are those the only openings?** A: 3 of the ports (blue ones) are 3/8 threaded NPT female Typically a threaded barb connector is screwed in to attach reinforced vinyl tubing with a hose clamp. A blue blue one with the 1.25 size (red one) should be on the high side of the tank when mounted and the blue one is attached to a vent tubing. The other two blue ones mounted at the bottom of that side. One has a tubing going to drain valve. The other is typically vinyl tubing to the input side of a 12VDC RV water pump. The large Red one) is a 1.25 inch. No threads. For use with a slip over flex tubing with a hose clamp for a gravity feed fill tube. Ideally this red port should be on the high side when you mount the tank. **Q: If I’m using this as a gray water tank, how do I drain the water out of it? What equipment do I need for that?** A: The tank has many 1/2” threaded holes so you can mount it many ways. Use one of the 1/2” holes and add water line and off/on valve to it. We use Pex waterline from Hdepot. Or you could use clearctubing **Q: What is everyone using to connect the large red nipple? It’s not threaded. Are you just slipping a clear hose over it with a pipe clamp and hoping i?** A: Yes, hose and a pipe clamp ## Frequently Bought Together - 16 Gallon RV Fresh/Gray Water Tank 24" x 15" x 10" BPA Free (16 Gallon) - A.A Fresh Water Tank Accessory Hose Connection Kit - RV, Concession, Trailer, Camper --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/391786302-fresh-gray-water-holding-tank-combo-rv-and-camper-bpa](https://www.desertcart.co.za/products/391786302-fresh-gray-water-holding-tank-combo-rv-and-camper-bpa) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-10-23*
