5. Setup and Installation
This section outlines the general steps for installing the PROFLO PF5114M Jerrit Toilet Tank onto a compatible toilet bowl. Ensure the toilet bowl is already securely installed according to its manufacturer's instructions.
5.1 Preparation
- Ensure the water supply valve is turned off and the toilet bowl is clean and dry where the tank will sit.
- Inspect the tank and all components for any damage. Do not install if damaged.
5.2 Tank-to-Bowl Connection
- Place the large rubber tank-to-bowl gasket over the flush valve shank on the underside of the tank. Ensure it is seated firmly and evenly.
- Carefully align the tank over the bolt holes on the back of the toilet bowl. Lower the tank onto the bowl, ensuring the gasket creates a seal and the flush valve tailpiece passes through the opening in the bowl.
- Insert the tank-to-bowl bolts through the holes in the tank and bowl. Secure them from underneath the bowl with washers and nuts. Tighten the nuts evenly, alternating between bolts, until the tank is snug and stable. Do not overtighten, as this can crack the ceramic.
5.3 Water Supply Connection
- Connect the flexible water supply line (not included) from the shut-off valve to the fill valve shank on the underside of the tank. Hand-tighten first, then use a wrench for a final quarter-turn. Do not overtighten.
- Slowly turn on the water supply valve, checking for leaks at all connections.
- Allow the tank to fill. Once full, check for any internal leaks or issues with the fill valve.
5.4 Final Steps
- Test the flush mechanism several times to ensure proper operation.
- Place the tank lid securely on top of the tank.
6. Operation
The PROFLO PF5114M Jerrit Toilet Tank operates using a standard flush lever mechanism. To flush the toilet, simply press down on the flush lever located on the side of the tank. This action lifts the flapper or flush valve, allowing water to flow from the tank into the toilet bowl, initiating the flush cycle. Once the tank is empty, the flapper closes, and the fill valve refills the tank to the appropriate water level.
7. Maintenance
Regular maintenance helps ensure the longevity and efficient operation of your toilet tank.
7.1 Cleaning
- Clean the exterior of the tank with a soft cloth and mild, non-abrasive cleaner. Avoid harsh chemicals or abrasive scrubbers, which can damage the ceramic finish.
- For internal cleaning, periodically add a toilet bowl cleaner designed for tanks (follow product instructions) or use a solution of white vinegar to help prevent mineral buildup.
7.2 Leak Checks
- Regularly inspect the base of the tank and the water supply line connection for any signs of leaks.
- Check the flapper or flush valve for proper sealing. A worn flapper can cause continuous running water.
7.3 Internal Components
- Periodically check the fill valve and flush valve for wear or damage. Replace components as needed with genuine PROFLO parts or compatible alternatives.
- Ensure the flush chain has the correct amount of slack; too much or too little can affect flushing performance.
8. Troubleshooting
This section addresses common issues you might encounter with your toilet tank.
| Problem | Possible Cause | Solution |
|---|---|---|
| Water continuously runs | Worn or misaligned flapper; fill valve not shutting off; flush lever stuck. | Adjust or replace flapper; adjust fill valve float; ensure flush lever moves freely. |
| Weak or incomplete flush | Insufficient water level; flapper closing too quickly; clogged siphon jet in bowl (not tank). | Adjust fill valve to increase water level; check flush chain for proper slack; consult bowl manual for clogs. |
| Tank not filling | Water supply valve closed; fill valve malfunction; clogged supply line. | Open water supply valve; inspect/replace fill valve; check supply line for kinks or clogs. |
| Leaks at tank base | Loose tank-to-bowl bolts; damaged tank-to-bowl gasket; cracked ceramic. | Tighten tank-to-bowl bolts evenly (do not overtighten); replace gasket; if ceramic is cracked, tank replacement is necessary. |
