Should there be water in the tank with a FLUSHMATE?

When you flush, a small amount of water might come out from the upper supply group. However, there is a drain located at the base of the FLUSHMATE® system that will remove most of this water. After flushing, you may notice a small amount of residual water (less than 1 inch) remaining in the china holding tank. This is completely normal and nothing to worry about.

How do I lower the pressure on my FLUSHMATE toilet?

To fix a toilet that is not filling up with water, follow these steps: 1. First, locate the water supply valve and turn it off. This valve is usually located near the bottom of the toilet, close to the wall. 2. Flush the toilet to relieve any remaining pressure in the system. 3. Next, disconnect the water supply line from the supply shank, which is the metal tube connected to the bottom of the toilet tank. You may need a wrench to loosen the nut. 4. Take a look at the inlet screen, which is a small filter located inside the supply shank, and remove any debris or objects that might be blocking the water flow. You can use a small brush or your fingers to clean it. 5. Once the screen is clean, reattach the water supply line to the supply shank and make sure it is tightly secured. Then, open the water supply valve fully to allow water to flow back into the toilet tank. By following these steps, you should be able to fix the issue of a toilet not filling up with water. If the problem persists, it may be necessary to seek professional assistance.

What is the minimum pressure for a pressure assist toilet?

Pressure-assist toilets function optimally when the water pressure ranges from 25-40 psi. When buying a pressure-assist toilet, it is crucial to ensure that the valve and bowl are compatible. A notable advantage of power-assist flushing is that the water is enclosed within the pressure tank, which is located inside the toilet tank made of china.
