Shuts Off Water Supply to Faucets
Saves Water and Energy · Prevents Tub Floods
Requires No Electrical Supply or Maintenance
Automatic Reset When Faucets are Turned Off
Flowban stops Tub Floods. It shuts off the water to the faucets, so bathtub overflows are a thing of the past.
It can also be used on certain types of Lavs and Sinks to stop them overflowing.
Flooding from overflowing baths causes water damage that is expensive to repair. In high rise properties such as Multi Family and Hotels just one flooding bathtub can cause massive damage to multiple units and rooms.
Even when a tub doesn’t overflow, because the waste can take care of the incoming water, the water flowing down the drain is wasted, as is the energy that has been used to heat it. Flowban saves water and saves energy.
Flowban is an insurance policy against tub flood damage. Maybe you will never need it but you can rest assured that a catastrophic tub flood event will never happen where a Flowban is installed.
There are many leak and flood detection devices that tell you there is already a flood, but only Flowban can stop flooding before it even starts. It uses no electrical sensors or a “memory” of normal flow and usage. It is a purely mechanical system that reacts when the water reaches a certain level in the tub. It resets itself automatically as soon as the faucets are turned off.
How Does Flowban Work?
Flowban is connected to the overflow pipe between the outlet from the tub and the waste. The hot and cold pipes are connected to the supply ports either side of the float chamber. When the water level in the bath reaches the overflow outlet, water enters the central chamber and activates the float. As the float rises, the magnets that are set into each end of the float repel the magnets on the flapper valves in the supply ports. The flapper valves are pushed into the water flow where the water pressure holds them in the shut position. A trickle of water is allowed to bypass the flapper valve and out of the faucet. The trickle indicates the faucet is still open, but the water level will drop and the central chamber drain. This allows the float to revert to its rest position, but the flapper valves stay shut, held in place by the water pressure. Once the faucet is turned off, the pressure equalizes each side of the flapper valve, it is then drawn back to the open position by the magnet on the float. The faucet can now be opened again, and full flow will resume.
Location
Flowban must be installed in a location where there is access, enabling it to be removed in the rare event of it needing cleaning. It must be installed in a vertical plane and be attached to either 1 1⁄2” PVC or 1 1⁄2” brass waste pipe. It cannot be installed on a waste with a trip activator passing through the waste pipe. The water supply pipes are connected using John Guest push fit fittings. Female connectors are required on the bottom nipples and male inserts are required on the top. The flow direction must be from bottom to top. The supply lines can be either hot or cold water or pre-mixed. In the latter case the flow should be split below the unit and reconnected above it. If required, only one inlet may be connected. Faucets may be located anywhere on the bath tub as required. The faucet controls can be fitted either before or after the unit.

Efficiency
Flowban has only three moving parts. It uses no electricity, being entirely mechanical in operation. Resetting the system after shut off is simply intuitive. No user instructions are necessary and, if the installation is hidden by a bath panel, there is no need for anyone to know that a flood prevention device is fitted.
Maintenance and Servicing
Under normal usage conditions Flowban requires no maintenance or servicing. However it is recommended that a bi-annual check is carried out to confirm correct functioning of the unit.
If foreign matter is obstructing the movement of the float in the central chamber then cleaning will be required but access to the chamber is very simple.
