Is the water clean?
Yes, the water comes directly form the water supply line. It is no different than the water from your faucet.

Where does the water drain?
Properly installed, the water drains to the toilet bowl, not into the tank.

Does the sink “recycle” water?
Yes and no. The water running in the sink is clean tap water. The device simply provides access to clean water which is normally used to refill the toilet bowl. When used as a finger rinse, the water that drains from the sink is considered “grey water”, or used water. In this way, the bowl is refilled with grey water instead of clean water, which is considered recycling.

How does the sink save water?
Access to the clean water that would otherwise go unnoticed into the drain system (toilet bowl) can be considered a savings of water. When used as a finger rinse, an additional use of tap water is eliminated (this can add up to gallons of water per day). Even when not used as a finger rinse, the pleasurable and soothing presence of a fountain is an added benefit, gained from otherwise wasted water. Most importantly, the sink provides a visual indication of a sometimes “stealth”-like leak within the toilet’s plumbing system. Undetected toilet leaks have been calculated to account for an amazing 5% of our nation’s water supply.

How does the sink affect the toilet?
The sink has no effect on the toilet’s function. Since the device is connected to the toilet’s refill cycle, there is no impact on the toilet’s flush. It may be that the toilet’s water pressure must be adjusted, which only affects the time it takes the toilet to refill.

Why does the water run so long?
The water runs for as long as it takes to fill the tank, as it always has. The sink only makes you aware of the amount of water that is needed to refill the bowl. The toilet requires no more or less water than it ever has.

Can the tank lid sink replace my bathroom sink?
The tank lid sink is not intended to replace the bathroom sink. Most sinks are carefully designed to perform their many functions, and do so quite well. Though technically capable of performing many similar functions, the tank lid sink is ergonomically designed to accommodate only a finger/hand rinse and is physically designed to accommodate even the narrowest toilet tank.

Is the sink “code compliant”?
In the “lid replacement” format, the device is not code compliant (IAPMO Standards) and is considered a “user installed after market accessory”. However, codes may vary by municipality opening the possibility of the product to be accepted by local governing officials. A patented wall-mount version of the sink is currently being developed to meet national plumbing codes as well as the ADA’s assistive device requirements.
