Frequently Asked Questions
How do I know if the H3547 will fit my RV?
Measure your existing tank or underbelly compartment carefully. The H3547 requires a minimum space of 60" length x 24" width x 6" height. Check clearances around plumbing connections and mounting points. If you're replacing a Jayco 0160538 tank, the H3547 is a direct fit replacement.
Can I use this tank for both black water and gray water?
Yes, ICON holding tanks are designed for dual-purpose use. You can use the H3547 for black water (toilet waste), gray water (sink/shower drainage), or a combination system depending on your RV's plumbing configuration. The extra-thick polyethylene construction handles both applications.
Does this tank come with fittings and valves installed?
The H3547 comes with preinstalled drain and level sensors, but it does not include gate valves, vent fittings, or inlet connections. This allows you to customize the tank with fittings that match your specific RV plumbing setup. Shop our tank fittings collection for compatible accessories.
What makes ICON tanks better than standard replacement tanks?
ICON tanks are engineered with extra-thick polyethylene material (thicker than many OEM tanks), providing superior resistance to cracking, warping, and chemical damage. The seamless rotational molding process eliminates weak joints, and IAPMO/CSA certifications ensure the tank meets rigorous safety standards. Many RV owners report ICON tanks outlasting their original equipment tanks.
How do I install the H3547 holding tank?
Installation requires removing your old tank, positioning the H3547 in the underbelly compartment, securing it with mounting straps or brackets, and connecting the drain valve, vent line, and inlet plumbing. If you're replacing a Jayco 0160538, the sensor connections should match your existing wiring. Professional installation is recommended if you're not experienced with RV plumbing systems.
