Description

The Flushmate III system provides the highest performance capability available today in the ULF (Ultra-Low Fixture) category. At just 1.6 gallons per flush, this system consumes 20% less water per flush than traditional toilets. This remarkable performance is achieved by using compressed air inside the tank, which creates a “turbo-charged” flushing action for effective bowl cleaning.

This 503 Flushmate Kit fits in Gerber 21-012 One-Piece Toilets. It does not work with any other Gerber models, or other brands.

This Kit Replaces: F3G and F03

This 503 Flushmate Kit does not fit in American Standard 2045.013 One-Piece Toilets.

Features and Benefits

• Complete Replacement Tank Kit for quick and easy replacement of an existing Flushmate system.
• The peak flow of pressure-assist technology is more than double that of gravity-type fixtures at 70 gallons per minute.
• Since a pressure-assist bowl does not require a siphon to extract waste, the trap dimension is the same throughout. This allows for the easy removal of waste throughout the trapway.
• Flushmate equipped toilets stay cleaner due to a large water surface area and vigorous flushing action.
• Water is contained in the Flushmate vessel, and not in the porcelain tank. The result is a non-sweating toilet, so the floor around the toilet remains dry.
• Flushmate systems are designed so that their flush volumes cannot be adjusted. The water savings are sustained for the life of the fixtures.
• Uses less than 1.6 gallons (6 liters) per flush without sacrificing performance, which saves up to 20% more water than conventional technologies.

Operation and Maintenance

How this Flushmate System Works

1. The Flushmate vessel traps air, and as it fills with water, it uses the water supply line pressure to compress the air trapped inside.
2. When the pressure inside the vessel reaches 35 psi it is ready to flush. (The built-in water regulator limits the pressure to 35 psi)
3. When flushed, the compressed air pressure “pushes” water out of the vessel, through the toilet, and down the drain at more than two times the rate of a traditional gravity system. (A traditional toilet uses the gravity flow of the water in the tank to raise the water level in the toilet bowl until it overflows the drain spillway and creates a siphon which “pulls” the waste out of the bowl)
4. The vessel then refills and is ready for the next flush.

Flushmate Cleaning and Care

Use of petroleum-based lubricants or cleaning products containing chlorine (household bleach, drop-in blocks or tablets, disinfectants) that are applied or inserted into the toilet tank and/or Flushmate vessel will void your Flushmate Limited Warranty. The exterior of the tank and the entire bowl can be cleaned following the manufacturer’s recommendations or in the same fashion as any other toilet.

With each flush, a small amount of water may be emitted from the upper supply group. A drain at the base of the Flushmate system will eliminate most of this water. Depending on usage, you may see some residual water (less than 1”) in the china holding tank. This is a normal occurrence.

Flushmate Systems are designed to be used with a cold potable water system only, and use of non-potable water supply or a tempered or hot water supply will void your warranty.

Installing a Replacement Flushmate System

1. Turn off the water at the supply stop. Flush the toilet to relieve water and air pressure from the Flushmate system.
2. Disconnect water supply line from the supply shank (bottom left-hand side of toilet tank) and remove the plastic nut that holds the supply shank in place.
3. If necessary, disconnect the flush-rod from the flush-handle linkage. Remove the screws and clips that attach the flush-rod to the Flushmate vessel and use them to attach the flush rod to the new Flushmate vessel.
4. Loosen the nuts on the bolts protruding from the underside of the toilet tank. These nuts should be loosened by alternating between them instead of completely removing one at a time.
5. Once the nuts have been removed, lift the Flushmate tank straight up out of the toilet tank. Empty any residual water that may have accumulated in the china tank. Carefully set the tank down flat on its backside.
6. Remove the rubber washers from the bolts and install them on the new Flushmate tank.
7. If the Vessel-to-Tank gasket is attached to the old Flushmate remove it and place it on the new Flushmate. If a replacement gasket is required, the Gasket Kit is available.
8. If the Toilet Drain Valve Assembly is broken you will need to replace it.
1. At the inside bottom of the tank you will see a small the Drain Valve Assembly. Either pull it out or unthread it based on your fixture manufacturer.
2. If you have to unthread it out of the china tank you will need to put your fingers inside the large discharge outlet in the china tank and hold the locknut, while unthreading the Drain Valve Assembly.
3. Once you remove the Drain Valve Assembly, make sure that the small white plastic ball is intact. If the ball is missing you will need to remove it from the toilet bowl.
4. To remove this ball, you will need to remove the toilet from the floor, gently lay the toilet on the backside and gently rock the toilet back and forth from side to side until the ball rolls out.
5. Reinstall the toilet back onto the floor.
6. Install the new Drain Valve Assembly, do the reverse as you did to remove it.
9. Reinstall the Flushmate Vessel into the china tank by aligning the bolts through the holes and the threaded shank through the larger hole on the left-handed side.
10. Attach brass washers and hex nuts to each bolt and tighten securely. (When tightening the tank to bowl nuts, use the alternating method while putting downward pressure on each side as you tighten the nuts on that side. You must get the bolts tight enough to prevent any leakage (when flushed) between the tank and the bowl, but not so tight that you risk breaking the china.
11. Re-Install the handle and rod kit as appropriate.
12. Reattach water supply line to the supply shank and turn on the water supply valve.
13. Wait for Flushmate vessel to fill with water and flush the toilet.

Warranty Info

5 Year Limited Warranty

Product Message

Flushmate systems will NOT work in traditional gravity fed toilets. Flushmate equipped toilets have specially designed water passageways in the bowl, and the bowl outlet has a completely different design which is much more open than traditional toilet bowls.
