  8. Flush Ball and Valve System – The flush ball system in this throne prevents water from escaping from within the bowl, thus maintaining clean water. Using the ball system in combination with a valve, the black box retains all the unwanted odors inside of it. This ensures the absence of any unpleasant odors in your entire bathroom.

Installation requirements

First of all, contact a qualified service professional for help in relocating your toilet.

Make sure that your current toilet:

  1. Has water supply lines can pass through the wall or floor of the building. A floor-mounted elbow adapter kit is required if the line exits the floor.
  2. Has two bolts perpendicular to the back wall attached to the floor.
  • The correct color Universal Mounting Kit is required if there are four bolts.
  • You may use a Universal Mounting Kit if you want to change the orientation of the toilet or you can replace the floor flange with the one that aligns with your preferred orientation.
  1. Has a level surface. It may be necessary to use a taller seal than the one provided if you are installing the flange in the sub-floor.

Also, make sure you have enough space for the new toilet to fit in perfectly. Compare the dimensions of both; the old and new toilets and also verify the door swing clearance.

How to Install

How to Install Dometic 300 Series Toilet

  1. Attach the new T-bolts to the floor flange. The new floor flange seal should be installed on the toilet’s base (It comes preinstalled on some models). The toilet should now be placed over the flange of the floor carefully.

  3. Fix the floor mount nuts firmly. Avoid overtightening.
  4. Install the ground mounting cap on the ground mounting nut. In case of a wet floor, to prevent water from seeping under the base of a toilet installed, apply a bead of caulk around its base.
  5. The water supply line should be connected and the connection torqued to 30–40 in. lb. Make sure you don’t overtighten. You will need to install a 1/2-inch water supply line if it is located on the floor.
  6. Now turn on the water supply. Perform several flushes and make sure there is no leakage.
  7. Pour water into the bowl and let it stand for an hour and then check again.
