Setup and Installation
This section outlines the general steps for installing the PROFLO PF3712DF toilet tank onto a compatible toilet bowl. Ensure your toilet bowl is clean and ready for tank installation.
- Prepare the Toilet Bowl: Ensure the toilet bowl is securely installed and the mounting surface for the tank is clean and level.
- Install Tank Gasket: Place the large rubber tank-to-bowl gasket onto the threaded outlet at the bottom of the toilet tank. Ensure it is seated properly for a watertight seal.
- Position Tank on Bowl: Carefully lift the toilet tank and align the two bolt holes on the bottom of the tank with the corresponding holes on the back of the toilet bowl. Gently lower the tank onto the bowl, ensuring the gasket compresses evenly.
- Secure Tank to Bowl: Insert the tank-to-bowl bolts through the tank and bowl holes. From underneath the bowl, place a washer and then a nut onto each bolt. Hand-tighten the nuts initially.
- Tighten Bolts: Using a wrench, alternately tighten each nut a quarter turn at a time. Do not overtighten, as this can crack the vitreous china. The tank should be snug and stable on the bowl without rocking.
- Connect Water Supply: Connect the flexible water supply line (not included) from the shut-off valve to the fill valve shank at the bottom of the toilet tank. Hand-tighten, then use a wrench for a final quarter-turn. Do not overtighten.
- Restore Water Supply and Check for Leaks: Slowly turn on the main water supply valve. Allow the tank to fill. Inspect all connections (tank-to-bowl, water supply line) for any signs of leaks. If leaks are present, gently tighten the connections until they stop.
- Adjust Water Level (if necessary): The fill valve is typically pre-set, but if the water level is too high or too low, refer to the fill valve manufacturer's instructions for adjustment. The water level should be below the top of the overflow tube.

Operating Instructions
The PROFLO PF3712DF features a dual flush mechanism controlled by the left-hand trip lever.
- Light Flush (1.0 GPF): For liquid waste, push the trip lever down briefly and release. This activates the lower volume flush, conserving water.
- Full Flush (1.28 GPF): For solid waste, push the trip lever down and hold it for a longer duration (approximately 3 seconds) or push it upwards. This activates the full volume flush.
Maintenance
Regular maintenance ensures optimal performance and longevity of your toilet tank.
- Cleaning: Clean the exterior of the tank with a soft cloth and mild, non-abrasive cleaners. Avoid harsh chemicals or abrasive pads, as they can damage the finish.
- Internal Components: Periodically inspect the fill valve, flush valve, and flapper for wear or damage. Replace components as needed.
- Leaks: Regularly check for any signs of leaks around the base of the tank or the water supply connection. Address leaks promptly to prevent water damage.
- Water Quality: In areas with hard water, mineral deposits may accumulate. Occasional cleaning of internal components may be necessary to maintain efficient operation.
Troubleshooting
Refer to the following table for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Tank not filling or filling slowly | Water supply valve closed; clogged fill valve; low water pressure | Open water supply valve fully; clean or replace fill valve; check household water pressure |
| Tank continuously runs | Flapper not sealing; fill valve not shutting off; trip lever sticking | Inspect and replace flapper; adjust or replace fill valve; ensure trip lever moves freely |
| Weak flush | Low water level in tank; partially closed flapper; clogged rim jets in bowl | Adjust water level to correct height; ensure flapper opens fully; clean rim jets |
| Water leaks from tank base | Loose tank-to-bowl bolts; damaged tank-to-bowl gasket | Tighten tank-to-bowl bolts evenly; replace tank-to-bowl gasket |
