Setting Up Your Retention Tank
- Position the Watts RT80 tank on a level, stable surface capable of supporting the full weight when filled (approximately 750 lbs total with water).
- Install an appropriate vacuum/pressure relief valve in the plumbing system as required for safe operation. Connect inlet and outlet piping to the top-mounted buttress-threaded fittings using the included 1-1/4" x 1-1/2" PVC solvent fitting kit.
- Install the 1" blow down drain at the bottom of the tank, adjusting the 360° orientation as needed for your drain line configuration.
- Fill the tank slowly while monitoring for leaks at all connections. Verify the vacuum/pressure relief valve operates correctly before placing the system into regular service.
System Integration
The Watts RT80 retention tank is designed for integration with commercial and residential water treatment systems requiring bulk storage capacity. The top-mounted inlet/outlet design easily accommodates vacuum breakers and standard PVC plumbing connections. Compatible with reverse osmosis systems, well water treatment setups, and other applications requiring pressurized water storage up to 75 psi. The corrosion-resistant fiberglass and polyethylene construction makes it suitable for both treated and untreated water storage within the specified temperature range.
