A tank that's off by an inch in any direction may not seat properly, may stress your plumbing connections, or may not pass through the access opening in the chassis. The 449H is the OEM-specification replacement for the exact footprint it was designed to fill.\u003c\/p\u003e\n\u003cp\u003eElkhart Plastics and Ameri-Kart supply the majority of OEM tanks to RV manufacturers in Indiana.

If you can locate the part number stamped on the old tank, that's the fastest way to confirm compatibility. If your bay is deeper or narrower, browse our other RV holding tank sizes.

This 30 gallon RV holding tank from Elkhart Plastics uses advanced roto-molding technology where high-density plastic is rotated and molded into a seamless shape with equal wall thickness throughout. Unlike cheaper welded or seamed tanks that develop leaks at joints, this seamless construction eliminates failure points entirely. The right end recessed drain positioning ensures proper drainage and compatibility with your existing plumbing configuration, while the blank tank design gives you complete control over fitting placement. Whether you're replacing a black water tank, gray water tank, or configuring a custom waste management system, this tank delivers the durability and precision fit that RV owners and mobile technicians demand.\u003c\/p\u003e\n\n\u003ch2\u003eCompare 30 Gallon RV Holding Tanks\u003c\/h2\u003e\n\u003cp\u003eNot sure which 30 gallon holding tank is right for your RV?

Before installation, carefully measure your available mounting space to ensure proper fit—remember to account for the 3-inch drain fitting, vent connections, and mounting hardware which will add to the overall height requirement. The tank should be securely mounted using appropriate straps or brackets rated for the weight of a full tank (30 gallons of water weighs approximately 250 lbs) to prevent movement during travel.\u003c\/p\u003e\u003cp\u003eThis tank features a standard 3-inch termination fitting that's compatible with most RV waste systems, including standard drain valves, gate valves, and dump hose connections.

The similar EPI 2873 (H1128) is 29 gallons at 7\" height, while the EPI 4273 (H1256) is 30 gallons at 6\" height with a right end recessed drain. Choose based on your exact space constraints and drain location requirements.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this tank fit my RV?\u003c\/strong\u003e The EPI 4339 is designed for installations where you have at least 60\" length, 28\" width, and 6.125\" height clearance, plus additional room for fittings and connections. Measure your available space carefully, including clearance for the drain valve and vent pipe, to ensure proper fit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use this for both gray water and black water?\u003c\/strong\u003e Yes, this tank can be used for either gray water (sinks\/showers) or black water (toilet waste) applications. The black polyethylene construction and seamless design make it suitable for both types of waste water storage. Just ensure you use it for one purpose only—never switch between gray and black water use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if this is the right replacement for my damaged tank?\u003c\/strong\u003e Check your existing tank for part numbers—if you see EPI 4339, H1259000, or H1259003 stamped on the tank, this is an exact replacement. If you have different part numbers, measure your tank dimensions carefully (length, width, height) and note the drain location, then compare to this product's specifications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat makes Elkhart Plastics tanks better than aftermarket alternatives?\u003c\/strong\u003e Elkhart Plastics manufactures OEM tanks for major RV brands including Forest River, Keystone, Thor, and many others.

The EPI 4580 offers a balanced footprint that works well in most applications. For tighter vertical clearance, consider the low-profile Alpha 207BLANK or EPI 4339. For more compact floor space, the EPI 4733 provides a taller, narrower option.\u003c\/p\u003e\u003ch3\u003eManufacturing Note: Sealed Top Hole\u003c\/h3\u003e\u003cp\u003eYou may notice a sealed hole on the top of the tank. This is a normal part of the rotational molding manufacturing process - it's a venting hole used during tank creation and has no functional use for the end-user. This is standard on all rotationally molded tanks and does not affect performance or durability.\u003c\/p\u003e\u003ch3\u003eInstallation Considerations\u003c\/h3\u003e\u003cp\u003eThis blank tank design provides maximum flexibility for custom installations. Professional installation is recommended to ensure proper fitting placement, secure mounting, and leak-free connections. When installing, ensure adequate support across the tank bottom, proper venting, and secure all fittings with appropriate sealants rated for RV holding tank applications.\u003c\/p\u003e\u003ch3\u003eBlack Water vs. Gray Water Applications\u003c\/h3\u003e\u003cp\u003eThis tank is suitable for both black water (toilet waste) and gray water (sink\/shower drainage) applications. For black water use, the 3\" hub outlet is recommended to handle solid waste efficiently. For gray water applications, either the 3\" outlet or the 3\" x 1-1\/2\" reducer outlet works well, with the reducer option providing compatibility with smaller drain lines common in gray water systems.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eQ: Does this tank come with fittings installed?\u003c\/strong\u003e\u003cbr\u003eA: No, this is a blank tank without pre-installed fittings. This allows you to customize fitting placement for your specific installation. Fittings are available separately and can be added per quote.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: What's the difference between the 3\" hub outlet and the 3\" x 1-1\/2\" reducer outlet?\u003c\/strong\u003e\u003cbr\u003eA: The 3\" hub outlet maintains full 3\" diameter for maximum flow (ideal for black water). The 3\" x 1-1\/2\" reducer outlet steps down to 1-1\/2\" diameter (common for gray water drain lines).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: Will this tank fit my RV?\u003c\/strong\u003e\u003cbr\u003eA: Measure your available space carefully. This tank requires at least 30\" length, 21\" width, and 13\" height clearance, plus additional space for fittings and connections.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: Is this tank UV resistant?\u003c\/strong\u003e\u003cbr\u003eA: Yes, the black polyethylene material provides excellent UV resistance for long-term durability.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: What's the wall thickness?\u003c\/strong\u003e\u003cbr\u003eA: This tank features 0.180\" wall thickness for superior strength and impact resistance.\u003c\/p\u003e\u003ch3\u003eWhy Buy from Elkhart RV Parts?\u003c\/h3\u003e\u003cp\u003eAs an authorized Elkhart Plastics dealer, we guarantee 100% authentic OEM-grade tanks backed by manufacturer quality standards.

It's a venting hole used during tank creation and has been properly sealed by the manufacturer. This hole has no functional use for the end-user and does not affect the tank's performance, integrity, or warranty.\u003c\/p\u003e\n\n\u003ch3\u003eCan I install fittings myself on this blank tank?\u003c\/h3\u003e\n\u003cp\u003eWhile it's possible for experienced DIYers to install fittings, we recommend professional installation to ensure proper placement, sealing, and compliance with RV plumbing standards.
