The Valterra No-Fuss Flush system is a waste holding tank flushing system designed for factory or field installation. The system utilizes a direct water connection to flush the waste holding tank, and requires specific installation procedures and operational precautions. This article details the installation process, operational guidelines, and safety considerations based on available documentation.
Installation Procedure
Installation of the No-Fuss Flush system requires several steps to ensure proper functionality and prevent leaks. The process begins with preparing the waste holding tank.
- Hole Preparation: A 1-inch diameter hole must be drilled into the side or end of the waste holding tank. This hole should be positioned no more than 2 inches from the top and near the center of the tank.
- Flusher Insertion: The No-Fuss Flush flusher is inserted into the prepared hole, ensuring it is in the “top” position as indicated by the stamping on the flusher unit.
- Lead Hole Drilling: After inserting the flusher, 1/8-inch lead holes must be drilled into the tank.
- Sealing and Fastening: Clear silicone sealer (substitution is not recommended) is applied completely covering the inside of the flange, with a thickness of approximately 3/16 inch. The flusher is then fastened using #8 – 1/2 inch stainless steel screws provided with the system.
- Silicone Curing: The silicone sealant must be allowed to cure completely, following the manufacturer’s instructions on the sealant tube, before proceeding to testing.
- Vacuum Breaker Installation: A vacuum breaker-check valve must be installed a minimum of 6 inches above the highest flood level rim of any fixture connected to the waste holding tank. Both valves are directional and must be installed accordingly.
- System Testing: Once the silicone has cured and all components are installed, the system should be tested for leaks with a minimum water pressure of 40 PSI.
- Caution Sticker: An enclosed caution sticker must be affixed to or near the water inlet of the system.
Operational Guidelines
The No-Fuss Flush system is designed for straightforward operation, mirroring procedures commonly found at campground dump stations. However, specific guidelines must be followed to ensure safe and effective use.
- Sewer Hose Connection: Connect a sewer hose to the appropriate outlet.
- Dump Valve Operation: Open the dump valve and allow the tank to empty.
- Water Supply Connection: Attach a garden hose to the water inlet labeled “Sewer Valve Must be Open When Using This Inlet”.
- Flushing Procedure: With the faucet at full pressure, flush the system for approximately 2 minutes, or until water runs clear from the discharge hose.
- Hose Disconnection and Drainage: Disconnect the garden hose from the faucet and lay it on the ground to allow water to drain from the system before detaching it from the water inlet.
Important Cautions and Restrictions
Several critical cautions and restrictions apply to the installation and use of the No-Fuss Flush system. Adherence to these guidelines is essential for preventing damage, ensuring safety, and maintaining system integrity.
- Potable Water Hose Prohibition: The same hose used for the No-Fuss Flush system must not be used to fill the potable (fresh) water tank.
- Dump Valve Requirement: The dump valve must be open any time a hose (water supply) is connected to the system.
- Hose Disconnection When Not in Use: No hose (water supply) should be left connected to the system when it is not in use.
- System Alteration Prohibition: The system must not be altered in any way, such as by adding check valves or other modifications.
- Backflow Preventer Restriction: No other backflow preventers, beyond those included with the system, should be connected to it. A water inlet with a check valve should not be used.
- Component Replacement: If replacement parts are necessary, they must be equivalent to and installed in accordance with IAPMO TSC 27 A2065 Valterra Products, LLC.
Component Specifications and Compliance
The documentation references compliance with specific standards for component replacement. Replacement parts must meet the requirements of IAPMO TSC 27. The system includes a vacuum breaker-check valve, which is directional and requires correct installation.
Additional Notes
The documentation notes that if it is necessary to add any parts to this system, the parts shall be the equivalent of and installed in accordance with IAPMO TSC 27.
The provided source material is insufficient to produce a 2000-word article. Below is a factual summary based on available data. The documentation focuses primarily on installation instructions, operational guidelines, and safety precautions for the Valterra No-Fuss Flush waste holding tank flushing system. The system requires a 1-inch hole to be drilled in the waste holding tank, proper sealing with silicone, and adherence to specific connection and flushing procedures. Crucially, the documentation emphasizes the importance of not using the same hose for potable water, keeping the dump valve open during flushing, and avoiding any alterations to the system. Replacement parts must comply with IAPMO TSC 27 standards. The system also requires the installation of a vacuum breaker-check valve at a specific height above the flood rim of connected fixtures. A caution sticker must be applied near the water inlet. The documentation stresses the importance of following these guidelines to ensure safe and effective operation.
