I bought a Glacier Bay Pull-Down Faucet from Home Depot and we're trying to install it. The spicket head keeps swiveling back and forth and won't stay stationary because of the hose. Does anyone know how to tighten the spicket so it will move and stay over one sink or the other?

Either tighten the nut that attaches the hose to the faucet body until the hose does not try to twist, this should not take ove a half of a turn.
Also you might be able to turn the spray head on the hose to accomplish the same thing.

Let me know if this advice helped.

Can you give us its Model number ?
