Please note that the images are for reference only. The product shown in this article may differ from yours, but the information below is still relevant.
To remove and replace a flush valve, you must
- Close the shut-off valve.
- Drain out water in the toilet tank.
- Remove the existing fill valve.
- Setting the new fill valve height and float location based on dimension is recommended at the end of the article.
- Replace the new fill valve.
- Reinstall the refill restrictor and the refill tube.
- Refill the tank and test for leaks and for flushing function.
Please note: Before doing any work on your toilet, please shut off the water supply to your toilet.
Once the water is turned off, you are ready to begin.
Step 1 – Close the shut-off valve and drain out the water in the tank
- Shut the water off by turning the shut-off valve clockwise
Step 2 – Drain out water in the toilet tank
- Drain as much water out as possible by holding the tank lever down until water within the toilet tank is flushed out completely. Use a sponge or a cloth to drain out the remaining water in the tank.
Step 3 – Remove the existing fill valve
- Disconnect the refill tube from the flush valve overflow tube
- Loosen and remove the coupling nut.
- Loosen the locking nut to allow the fill valve to be removed.
Step 4 – Setting the new fill valve height and float location
- Loosen the lock ring to adjust the Total height of the fill valve(A) based on the dimension recommended at the end of the article. Then lock the nut.
- Adjust the float location to meet the recommended dimension B
Step 5 – Replace the existing fill valve
- Tighten the locking nut to make sure the fill valve seals well.
Recommended torque range is 5-8ft.Ibs（60-96in-Ibs） - Reinstall the coupling nut.
Step 6 – Reinstall the refill restrictor and refill tube
- Reinstall the corresponding colored refill restrictor based on the tank model number marked inside your toilet tank. Refer to the corresponding model number in the reference table at the end of the article.
- Reattach the refill tube to the flush valve overflow tube. Make sure the refill tube adaptor is attached directly to the overflow tube. Flow from the refill tube must be positioned directly into the overflow tube.
Step 7 – Refill the tank and test for leaks and for flushing function
- Reopen the water by turning the shut-off valve counter-clockwise to refill the tank.
- When the tank is refilled, verify if the water is filled to the level at the marked water line on the back wall of the tank. Adjust the water level if needed by turning the water level adjustment on the fill valve to move the float cup up or down to increase or reduce the water level in the tank.
- Press the tank lever down to activate the full flushing cycle. Verify if the toilet flushes and refills without issue, and the flapper seals well when the flushing cycle is completed.
