Frequently Asked Questions

My flush is poor/not strong enough, what do I do?


  1. Please turn your water off and empty the tank before starting. This makes it easier to reach the parts needed.
  2. Remove the flush valve. If you twist the unit slightly and lift up the whole piece should pop right out.
  3. Before adjusting any dials, turn the unit over and check the seal on the very bottom. Make sure it is not damaged in any way.
  4. There is a small “ledge” you can fit your thumb on near the long, blue, plastic piece that looks like a ruler. Push this piece down all the way down until you see the number The piece should “click” in.
  5. To the left of that ruler piece, there is a small switch the size of your thumb. Make sure this is pushed all the way up. The arrow should be pointing at the “10.”
  6. You can then replace the flush valve, turn your water on and give a few test flushes.

These settings are the settings for maximum flush power.

*For all models except SM-1T803.

The water level in my bowl is very low, is there a way to adjust this?


In general, our toilets have a low water spot. If you wish to increase the water level inside of your bowl, there are small adjustments you can make.

Next to your flush valve inside of the toilet tank, there is a small cylinder. On the top of this tube is a small dial. You can set the dial to “8” and this will slightly increase the water level in your bowl.

Please note that it may take time for the changes to appear.

I need to make adjustments to my fill valve, how do I do this?


Please be sure to have your water off and tank empty before you make these adjustments

The float on your fill valve can be adjusted by twisting the little screw on the end of the arm, above the float.

If that is insufficient, you can make larger adjustments by reaching on the side of the fill valve and flipping the switch (it is about the size of your thumb). This will “unlock” the fill valve and you should be able to slide the unit up or down to fit your needs.

This is the first step. Please let us know if this does not work for you

It may be hard to flip at first. But, this will allow you to make larger adjustments with your fill valve.

If this does not work, you may need to check the seal on your flush valve..

My seat appears too short/long for my toilet, what do I do?


This is a simple fix, the following is our guide to making adjustments.

  1. Disassemble
    · Disassemble the cover cap and the hinge.
  2. Construct Hinges
    · Insert screw and nut into the hole on the hinge.
    · Attach blind hole screw fixing to the bottom of the screw
  3. Attach Hinges
    · Insert hinges with blind hole screw fixings attached
    into holes in the toilet bowl.
    · Lightly tighten hinges with a screwdriver to allow
    for later adjustment
  4. Adjust and Cover Hinges
    · Be sure the hinge is all the way forward for a proper
    seat fitting.
    · Place the covers onto the hinges
  5. Adjust and Attach the Seat
    · Align the seat to the hinges then firmly tighten the hinges.
    · Attach the seat to the secure hinges.
    · Adjust the seat to align with the bowl.

Toilet Seat Usage

  • To remove, push the middle button until you hear a “click”, then pull straight up
  • To re-install, align hinge posts with reference marks on the seat, then push down until you hear a “click”.
What is the weight limit for your toilets?


When properly installed, our one-piece toilets can support up to 1,000 pounds.

What is the waterline connection size?


Our one-piece toilets use a standard 0.88" waterline. We generally recommend the braided chrome style lines.

ADA compliance is dependant on the toilet model. Please see product details on the individual product page for certification information.
