How do I get a brand new installation to Flush?

If your unit is a brand new installation that will not flush with the handle but appears to have filled correctly, the 2 lines that trace from the handle assembly to the center of the EcoFlush system may be restricted. Simultaneously, tap on the handle and begin to rearrange these hoses into a better position. Doing these two motions will eventually activate a flush at which point you may leave in this unrestricted position. 

How do I remove the handle?

The handle is a pressure fit and is removed by pulling directly forward on the handle. It maybe necessary to use a screwdriver to gain additional leverage. Be careful not to damage the tank or the handle

How do I replace my fill valve?

Replacing your fill valve with a WDI fill valve is simple. Watch this quick tutorial on how to replace your fill valve: 

Here are step by step instructions as well: 

Step 1. Disconnect the supply line

    • Turn off the water at the shutoff valve by turning the valve clockwise
    • Drain the tank by holding the flush lever down until toilet is completely flushed
    • Disconnect the old supply line
Step 2. Remove Old Fill Valve
    • Beneath the tank, loosen the lock nut that holds the fill valve to the tank
    • Remove the old fill valve
Step 3. Adjust New Fill Valve
    • The new fill valve will go on similar to the old one
    • Reattach the new fill valve and Adjust the height of the valve so the marking on top of the valve is at least 1 inch above the overflow tube
    • Turn the water back on.
    • Allow the tank to fill.
    • Test new fill valve and check for leaks. If leakage occurs, adjust water level as necessary
Step 4. Reconnect Water Supply Tube Back to the Tank

Step 5. Check New Fill Valve
      • Turn the water back on.
      • Allow the tank to fill.
      • Test new fill valve and check for leaks. If leakage occurs, adjust water level as necessary

    I've installed my EcoFlush pressure-assisting system and there is some water in the bottom of the tank. 

    This is normal. The height level of the water is approximately 1/2"-3/4". A drain located at the bottom of the vessel will discharge any water above this level. 

    Do I need to remove the zip-tie that connects the 3 locking tabs together?  

    No, this is for tamper resistance only. 

    I think there is a problem with my EcoFlush pressure vessel or WDI product.

    If you think there is a problem with your WDI or EcoFlush product, please turn off your water supply, consult your Owner's Manual as well as our problem solution guide under the support menu. If your problem still persists, please call our expert plumbing services team at 1(800) 391-9821.

    General Toilet Troubleshooting Questions: 

    My toilet's tank won’t fill completely.

    If your toilet tank won’t fill completely with water (to the manufacturer’s water line), your fill valve may need to be replaced.

    My toilet is making a squeaking sound.

    If your toilet is making a squeaking sound, your fill valve may need to be replaced.

    My toilet won’t stop running.  

    If the water in the tank is over the fill line and the toilet won’t stop running, then the toilet’s fill valve may be broken. If the water level is not abnormally high, then the problem may be related to something else (for example, the flapper).
    If the toilet won’t stop running and water is constantly trickling into your toilet bowl, your flapper may need replacement. You can check your toilet’s flapper for warping or cracks which may require the flapper’s replacement. Your flapper may also be the wrong size, to ensure that your flapper is the appropriate size for your toilet, please review your owner’s manual.

    My toilet is overflowing.

    Toilet overflows are most likely the result of either a blockage or an error in the tank float mechanism that regulates water flow.

    Step 1. Turn off Water Supply 
    • Remove the lid off the tank
    • Turn off the toilet's water supply by turning the valve counterclockwise to stop water flow to the toilet. 
    Step 2. Use a Plunger 
    • Align the rubber cup of a toilet plunger over the center of the hole of the toilet bowl. 
    • Apply downward pressure slowly at first, gradually increasing the speed and intensity. 
    Step 3. Use a Toilet Auger
    • If a plunger doesn’t work, use a toilet auger to fish out objects causing the clog that cannot be retrieved using a plunger.
    • Insert the tube end of the auger as deeply into the toilet hole as possible.
    • Apply gentle pressure to the cable and start turning the auger, extending the cable down the drain pipe of the toilet.
    • Pull the auger out of the hole.
    Step 4. Reattach the Supply Line
    • After the clog has cleared, reattach the water supply.
