 Wall mount faucet height
Author: sum (FL)

Always take proper measurements. There must always be a 1 inch gap between the bottom of the faucet and the top of the sink. If the gap between the top of the sink and bottom of the faucet is more than 1 inch, the water will splash out of the sink.

Don't let the faucet go inside the sink -- that's a code violation. You need 1 inch of airspace between the top of the sink's flood level and the bottom of the faucet," he says. On the other hand, if the faucet is too high, he cautions, water will splash out of the sink.



Is this the general rule of thumb? The top of the sink, add one inch, is the elevation for the bottom of the faucet?

That is a code requirement, and no manufacturer makes a faucet that would violate the requirement, although YOU can install the sink in such a way as to violate it and create a health hazard. The "not higher than 1" statement, is however ludicrous. Many if not most faucets are more than that. Mine is 4" higher, and some designer faucets will go as high as 8" above the sink rim. The design of the faucet is what determines whether it will splash or not, and that has NOTHING to do with how high it is.

the spout (outlet) must be a MINIMUM of 1" above the flood level (countertop level) of the sink as per ALL plumbing codes .... this is termed 'maintaining a minimum air gap' in order to prevent any possible backflow of sewage into the potable water


the faucet aerator should prevent 'splashing' as most kitchen faucets are designed to allow pot and pan clearance ... lavatory faucets come in so many styles that a dimension is not possible to give (except for the code rquired minimum)


? maufacturer's instruction/installation booklet ?

ps. 'hj' beat my response frowning

YOu are assuming he is referring to a wall mounted vessel sink faucet. If it is one of those, I go even higher.

Cross connection is dangerous to the health of not just yourself, but ALL the unsuspecting folks using the water supply.
If the tip of the faucet was to sit in the water in your sink, and the water supply pressure dropped, the resulting vacuum will suck that dirty water into the clean water supply.
It's the reason why most(not all) garden hose bibbs/spigots come with a built-in Vacuum Breaker.

Walkerton, Ontario, Canada lost about a dozen good people to cross connection.
A lot of cities/towns are demanding backflow prevention devices/valves to be installed on new builds. Plumbers can install them, but cannot legally turn the water on until the device has been thoroughly tested/tagged by a licensed tester.
Then, the device HAS to be tested every 1 or 2 years after that(depending on Province/State.)

Height is immaterial, as HJ said.
But, please make sure of your airgap, lest you poison the people you love, and/or your friends and neighbors.

I am referring to a wall mount vessel sink faucet. It is a lav sink and not the kitchen sink. The rim of the vessel sink will be at 33-1/2" above finished floor elevation. I have set the center line of the faucet to be at 36" above finished floor elevation, which is 2-1/2" above the rim.

However, the spout of the faucet has a down turn nozzle, and that end of the nozzle takes it another inch lower, and the nozzle does not point perfectly vertically down, but 10 degrees off. So I am just wondering if I should adjust if higher.

The sink is not a traditional "cone" shaped sink, but a rectangular shaped sink (Villeroy & Boch's Loop and Friends series), see picture below.



Wondering if I should adjust it higher...

As you can see in the picture, the faucet is mounted about 7" above the sink.

This faucet has a pretty significant down turn nozzle that shifts the bottom of the nozzle down a good two inches, the one I have does not reach that low. But I guess the point is it is of no harm to be a couple of inches higher than minimum? I think the downside may be splash, or if the nozzle is out too far, and the sink is set to near the wall, the trajectory of the water coming out of the nozzle ends on the front wall of the sink instead of the bottom?
