Toilette Fill Valve with Cleaning Tube HC660 and HC660C (Canada)

The award-winning HydroClean toilet fill valve solves the two biggest reasons for water loss in toilets – miscalibration and leaks. Ordinary fill valves send water to the bowl throughout the entire tank-filling cycle. The HydroClean can be calibrated to adjust the exact amount of water needed. It also detects leaks and signals when a leak is found. Proven in independent studies to reduce water usage by 36%, the feature-rich HydroClean cleans the tank, fits all standard toilets and installs easily without tools.

Invented by a fourth generation plumber, the HydroClean HC660:

  • Saves Water
  • Saves Money
  • Detects Leaks
  • Installs Easily Without Tools
  • Cleans the Tank

Fill Valve With Cleaning Tube FAQs

It’s possible that the valve is clogged. I have listed below how to “flush” the valve out and check the seal (inside the top blue cap) for any tears or punctures.

  1. Turn the water off going to the toilet.
  2. Place your palm on the top blue cap and push down with a little pressure.
  3. Turn the top blue cap counter-clockwise until it comes off and will hang on the thumbscrew.
  4. Cup your hand over the exposed part of the valve and slowly turn the water on going to the toilet.
  5. Let the water run for about 15-20 seconds, flushing any debris out.
  6. Turn the water back off.
  7. There’s a round black rubber seal in the center of the top blue cap. Please remove that seal and run it under water, looking for any tears or punctures.
  8. If no tears, please replace the black rubber seal inside the top blue cap and put the top blue cap back on to the valve by placing it on the valve body/stem and putting your palm on top and push down with a little pressure, turning the cap as far clockwise as it will go.

It is probably the leak detection. Use the steps below to verify that it is, in fact, a leak.

  1. Flush the toilet and let it fully refill.
  2. Mark the water level in the tank.
  3. Lock off the float lock on the HydroClean.
  4. Let it sit like that for about 30-45 minutes.
  5. If the water level has dropped, than there’s definitely a leak and must either be coming from the flapper or the flush valve. It’s possible that the flush valve has a scratch or tear in it and, therefore, is causing a leak.

This is normal operation. The HydroClean makes a distinct sound when it is refilling the tank because the jets first push air out of the valve then jets water to lift up all of the debris that may settle on the bottom of the tank. The jets also clean the inside of the tank, prolonging the life of the components.

This same sound is designed to alert you that there is a leak in the toilet. If you hear this noise when the toilet is not being flushed, see the previous FAQ.

Absolutely. You will lose about 80% of the cleaning, but you will still have leak detection and the valve will function properly.

Check the float to make sure it travels freely up and down and is not binding on side walls.

  1. Please place your palm up at the top blue cap. Push down with a little pressure and turn the cap as far clockwise as it will go.

If this doesn’t solve the issue, please try the following:

  1. Place your fingers at the top of the blue float and your thumb at the bottom, or vice versa, and squeeze those two pieces together, going all the way around the float.
  2. If it does not freely move up or down and is not binding on side walls you need to check the Float Lock
  3. See if the float lock is holding up the float.
  4. Float lock should be locked in approximately 1/2” away from the Float Screw during normal operations.

If it isn’t, make sure water is going through the supply line:

  1. Turn water off where it comes out of the wall.
  2. Unscrew the supply line from the base of the toilet tank.
  3. Put the open end of the supply line in a bucket or container.
  4. Turn the water back on slowly.
  5. The water should have strong flow. If not, please call a plumber, because the problem could be in the shut off valve or the supply line.

If water flows:

  1. Reconnect the supply line to the base of the toilet.
  2. Turn the cap of the valve counter clockwise to remove it.
  3. Check the seal on the cap for debris or damage.
  4. If there is debris remove it. If the seal has been damaged, replace the seal.

If there is no debris or damage:

  1. Place a cup or container over the top of the valve.
  2. Turn on the water very slowly. Water should flow through the valve.
  3. If the valve is plugged with large debris and sediment, this should remove the buildup.
  4. Turn water off.

When finished:

  1. Reattach the cap.
  2. Slowly turn the water back on.
  3. Test the toilet to see if the problem has been fixed.

Adjust the float to the proper height.

  1. Turn water off to the toilet at the wall.
  2. Turn the valve clockwise until you hear a click.
  3. Raise or lower the valve so that the center of float is approximately at the fill line inside of the toilet.
  4. Turn the valve counter clockwise to lock it back into place.
  5. Turn the water back on.
  6. Small corrections to water height can be made by turning the thumbscrew. Counter clockwise to lower the level, clockwise to raise the level (do not go past the threaded stop).

If the water is flowing over the over flow tube then the fill valve is adjusted too high. This means that the flapper could be leaking so fast that the fill valve cannot keep up.

  1. Shut water off at the shut off valve or by applying the Float Lock. If the water level drops, the flapper is the problem.
  2. Make sure the float moves freely up or down and does not bind or hit the side walls of the tank.
  3. Check the height of the float compared to the fill line inside the tank. If the height is incorrect, turn the water off where it comes out of the wall.
  4. Turn the valve clockwise until you hear a click.
  5. Adjust the float to the fill line inside of the toilet.
  6. Turn the valve counter clockwise to lock it back into place.
  7. Turn the water back on.
  8. Small corrections to water height can be made by turning the thumbscrew. Counter clockwise to raise the level, clockwise to lower the level.

Check the float lock.

  1. Float lock should be locked in approximately 1/2’ away from Float Screw.

If the float lock is functioning properly.

  1. Turn water off.
  2. Turn the cap of the valve counter clockwise to remove it.
  3. Check the seal on the cap for debris or damage.
  4. If there is debris remove it. If the seal has been damaged, replace the seal.

If there is no debris or damage:

  1. Place a cup or container over the top of the valve.
  2. Turn on the water very slowly. Water should flow through the valve.
  3. If the valve is plugged with sediment, this should remove the buildup.
  4. Turn the water off.

If there is only a minor drip, this is normal operation. All pilot valves are designed to weep during operation and will stop after the valve turns off. This does not waste water and is normal.

If it’s more than just a drip, check the seal.

  1. Shut the water off under the toilet tank
  2. Turn the cap of the valve counter clockwise to remove it.
  3. Check the seal on the cap for debris or damage.
  4. If there is debris, remove it. If the seal has been damaged, replace the seal.

Adjust the float to the proper height.

  1. Turn the water off to the toilet at the wall.
  2. Turn the valve clockwise until you hear a click.
  3. Adjust the float to the fill line inside of the toilet.
  4. Turn the valve counter clockwise to lock it back into place.
  5. Small corrections to water height can be made by turning the thumbscrew. Counter clockwise to lower the level, clockwise to raise the level.
  6. Turn the water back on.
