Flowban Stops Bathtubs & Sinks from Overflowing

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. Read more how Flowban stops overflows

In most conditions you would expect that the normal 1 1⁄2” overflow pipe fitted to a bathtub would be adequate to deal with the inflowing water. However, some installations have very high-water inlet rates to fill the tub quickly, especially jet tubs, so overflowing tubs are still common. On some jet tubs it takes eight minutes to fill it to the level where the jet tub can be used, but only five minutes later it will be overflowing. Even when the overflow does stop the tub flooding, water is being wasted and so is the energy used to heat it. Tubs left running for hours waste a lot of water and a lot of energy.

Flowban is fully mechanical in operation. It uses magnetically activated valves to shut off the water supply to faucets when the water level reaches the overflow and automatically resets when the faucets are turned to the closed position. No electrical connections or batteries are required.

How to Install Flowban

Flowban is a simple solution to the Bathtubs & Sinks Overflowing problem. Invisible to the bath user, it requires no extra sensor to be fitted inside the tub and no electricity supply to operate. It is intuitively self-resetting and Maintenance FREE. 

Flowban has been designed for easy installation using John Guest push fit connections. It must be located between the overflow outlet and the waste.

Faucets left unattended can result in bathtubs flooding which can cause expensive damage down multiple floors. Even if the overflow outlet can deal with the incoming water, something they often fail to do on jet tubs, the wasted water and the energy used to heat it is an unnecessary expense.

Faucets left running can easily be forgotten and within minutes the water can reach the overflow, a short time later it can be flooding the bathroom! Some people deliberately allow the faucets to keep running so they can continuously top up with hot water. This is very wasteful and can cause flooding as well.
