American Standard 1660400.243 – Frequently Asked Questions
1) Where does an in-line vacuum breaker like this one get installed on a handshower setup?
In line between the supply outlet and the hose, not at the shower head end. The 1660400 threads onto the 1/2-inch NPT outlet and the personal shower hose threads onto it, so the backflow protection sits upstream of the flexible hose that can end up lying in a tub.
2) Will this vacuum breaker work with my American Standard handshower?
American Standard states the 1660400 is compatible with all of its Personal Showers, and the 1/2-inch NPT thread is the standard handshower supply connection.
3) What finishes does the American Standard 1660400 vacuum breaker come in?
Five: chrome (1660400.002), polished nickel (1660400.013), matte black (1660400.243), brushed nickel (1660400.295), and Brushed Cool Sunrise (1660400.GN0). Order the code that matches the rest of the shower trim, since the breaker is visible once installed.
4) Is this vacuum breaker brass or plastic inside?
Brass. American Standard builds the 1660400 from brass for prolonged contact with water, with the finish applied over it.
5) Do I need to order anything else to install the 1660400 vacuum breaker?
Yes. The breaker is the fitting only. You supply the wall or tub spout supply outlet and the personal shower hose, which American Standard sells separately.
6) Is the American Standard 1660400 vacuum breaker meant for residential or commercial work?
American Standard classifies it as a residential product, in its luxury bath line. For multi-family or hospitality bathrooms it is still a handshower-scale 1/2-inch NPT fitting, but heavy commercial backflow requirements should be checked against your local plumbing code.
7) How much room do I need behind the wall outlet for this vacuum breaker?
American Standard lists the part at 7.244 by 5.157 by 2.874 inches and 0.309 lb, so allow clearance around the supply outlet before the hose drops. It is a light fitting, no extra bracing needed.
