Pro Tip: Measure your RV's tank compartment carefully before ordering. Consider not just the tank dimensions, but also clearance needed for fittings, mounting straps, and removal access.
Installation Considerations
Custom Fitting Installation: The molded outlet and 1-inch vent tube are shown in the retained print. Match these positions to your installation; do not assume the drain and vent can be placed arbitrarily.
Professional Installation Recommended: While experienced DIYers can install this tank, professional installation ensures proper fitting placement, secure mounting, leak-free connections, and compliance with RV plumbing standards.
Mounting and Support: Ensure adequate support straps or brackets to prevent tank movement during travel. The tank should be fully supported across its bottom surface to prevent stress cracking.
