Questions & Answers
Is there any way not to have water spraying from the little holes each time we are done using the...
Asked by Mels January 11, 2021Yes. In our case we have a hose attached to it and we just press the nozzle on the end of the hose to let water out and then close the bibb while still holding the nozzle lever. This does two things for us: (1) It gets as much water out of the hose as possible, and (2) stops the water from spraying through those little holes
You can’t fit a quick connect hose fitting The white piece inside is in the way Bummer
Asked by Yoz November 18, 2020That is correct, the white part will prevent this.
do I need a 3/4” vacuum breaker for a 1/2” hose bib?
Asked by Mary October 2, 2020At our house we have 1 hose bib that uses 3/4" copper pipe and two that use 1/2" copper pipe and have appropriate hose bibs, but the threads on all of these hose bibs are standard and are 3/4" Garden Hose Thread, so this will work for your 1/2" hose bib

Asked by JImbo August 15, 2020Will go to internet for further instructions to install. Don’t know where the above statement ‘The product description says’ comes from as no instructions given on package.
Can the set screw be removed before installing the breaker?
Asked by sus August 8, 2020Yes, however I go an extra step and replace it with "The Hillman Group 4419 M5-0.80 x 5mm Metric Stainless Steel Socket Set Screw (10-Pack)" which allows you to tighten the set screw with an Allen (Hex) Wrench. This passes code in jurisdictions requiring the breaker to be on and not easily removable and the added bonus is it is removable with the wrench so if you have to replace the breaker or the hose Hose Bibb you don't have to buy a new Vacuum Breaker.
Will this fit the Mansfield hose bib?
Asked by JD July 29, 2020Most hose bibs have a 3/4" male hose thread (there are some old very rare ones that have a 1" male hose thread) so this breaker will fit all 3/4" male hose threads, so it should fit your Mansfield Hose bib.
What is the difference between this one and other expensive ($20+) ones or are both the same?
Asked by Sandy June 30, 2020They both function the same although the more expensive one might last a little longer than the brass one but will need to be replaced down the road. Service life is dependant on water quality and hardness. My brass Bibb lasted 6 years before I needed to replace it - we have very hard water. You can buy 3-4 of the brass fittings for the price of the more costly unit which may only give you a year or two more years of service.
All the vacuum breakers/back flow preventers are 3/4 to 3/4 inch and my hoses are 5/8 inch diameter. Will that work?
Asked by K8Cole June 15, 2020Your 5/8 inch diameter hose will work fine because it uses standard 3/4 inch Garden Hose Fittings on both ends.
What is the diameter for the female end?
Asked by KIngFF June 1, 20203/4

Asked by Chris May 24, 2020Just use a reducer from 1 1/4 to 3/4.
