Customer Questions & Answers

What is the small knob for on the top of the faucet?

Asked by: SeniorAdvice
That's not a knob. It's the vacuum breaker for the anti-siphon function.

If is repairable?

I have one of these and water leaks out from behind the large plastic knob. Is it repairable? Or do I have to replace the entire faucet?
Asked by: Taumax
Yes, most faucets like this eventually leak at the packing washer. Turn off water supply. Usually remove handle, packing nut (reverse thread), then remove insert by "opening" faucet. Go to local h/w and take the washer and stem assy with you to make sure you get a new washer that fits tight !

Is this faucet drinking water safe? How can I tell if an outdoor faucet is drinking water safe?

1/2 in. x 8 in. Brass MPT x S Half-Turn Frost Free Anti-Siphon Outdoor Faucet Sillcock.
Asked by: Henry
Per the manufacturer's website, models with a -LF on the end of the number are lead free. Since this does not have the -LF, it likely has lead and would not be drinking water safe.

Customer Reviews

1/2 in. x 8 in. Brass MPT x S Half-Turn Frost Free Anti-Siphon Outdoor Faucet Sillcock is rated 4.0 out of 5 by 3.
Rated 4 out of 5 by from Nice if installed correctly This works nicely during the winter in New England assuming you install it correctly. You must get the tube perfectly level or slightly sloped to the outside. Otherwise it will freeze up since water does not flow uphill. As for the quality, it is made nicely.

Rated 3 out of 5 by from Not happy with this product The faucet was almost an inch longer than specified and the buyer pickup label was wrapped around and glued to the faucet tubing that goes into the wall.rather than the faucet assembly being put into a box or bag. Removing the label fron the faucet tubing was time consuming and difficult..
