Hi, this is Jeff. Today, I'd like to talk to you about backflow prevention, but before we begin, please note that it's important for you to check with your local municipality to find out their requirements regarding backflow prevention in your area. Backflow is the unintended reversal of the normal flow of water in a plumbing system. It's caused by one of two conditions: back siphonage and back pressure. Back siphonage occurs when the normal pressure in the system turns negative, causing a reversal of the normal flow of water in the system. Back pressure, on the other hand, is when the pressure on the outlet side of the fixture is greater, causing the water to reverse itself in the water system.
Fisher offers four general types of backflow prevention. We use an air gap, we use an atmospheric vacuum breaker, a dual check valve backflow preventer, and an anti-spill pressure style vacuum breaker. Each has its own unique application. Air gap is the distance between where the water comes out of the fixture and the flood rim of the sink. You need to maintain a minimum of 2" air gap. The dual inline check valve backflow preventer is used whenever you have a flexible air gap, such as on a pre-rinse where the outlet of the device could well be below the flood rim of the sink. Atmospheric vacuum breakers commonly found on kettle fillers and service faucets are designed to prevent back siphonage. The caution is that you are not allowed to have any shut-off valves downstream of the atmospheric vacuum breaker. Anti-spill pressure style vacuum breakers are commonly found on hose reel units. They protect against back siphonage, back pressure, and it's important to note that you can have valving on the inlet side of this and the outlet side of it. And they are not to be installed above ceiling tiles in the wall, it must be accessible for inspection. Backflow prevention can be quite complex, however, in the Fisher catalog we offer many kits and components to make the process quite simple. Be sure and check your local codes. Thanks for watching.

Hi, this is Jeff. Today I'd like to talk to you about 1/2" faucets. Whenever we talk about 1/2" faucets or 3/4" faucets, everyone wants to know the difference. Why is a 1/2" faucet a 1/2" faucet? Why do we call it that? And really, it's all about the pipe thread. On the 1/2" faucet, the inside diameter of the pipe is exactly a 1/2". That's why we call it a 1/2". The outside dimension is 3/4", which matches up a 3/4" outside, and a 1/2" on the inside, for a 1/2" faucet. That's what a 1/2" faucet is. Okay, so Fisher makes a variety of different types of different configurations of faucets. We make deck mount faucets, wall mount faucets, and backsplash mount faucets. When it comes to the spout, we make swing spouts, gooseneck spouts, double-jointed spouts, control spouts.... If you refer to the catalog, certainly you can find a faucet that would be perfect for your application. In addition to different styles of mounting and spout configurations, we also offer a variety of handles. Standard on all Fisher faucets is the standard lever handle; however, you can also pick up the optional cross handles and optional wrist blade handles. There's two things that we do differently that make Fisher the most specified brand in commercial foodservice. And that is... the first thing we do, is we use a stainless steel seat that's guaranteed for life. The reason why is that water is very corrosive and brass is very soft. Everyone else uses brass seats, so as the water flows in the bottom of the faucet and makes that first 90 degree turn to exist the faucet, the water will erode the brass seat. We use stainless steel seats that are screwed and glued into the faucet body, and we guarantee those for life. The second thing that we do is we use a two-part swivel stem, and what I mean by that is that at the end of the stem there is a seat washer. The seat washer is on a swivel, so that as the stem screws down the faucet body, as the seat washer makes contact with the stainless steel seat, it becomes a plunging action, rather than if this were all one piece, it would be a twisting and grinding action. Others all use a one-piece stem similar to this stem where the seat washer is attached right to the stem; so as this stem screws down through the body of the faucet and it makes contact with that seat, this seat washer is being torn up by an eroded brass seat. With Fisher, because it's on a swivel, as soon as this seat washer makes contact with the seat, it becomes more of a plunging action. This means longer life, lower maintenance. This is why we are specified. Just to recap, Fisher uses stainless steel seats that are guaranteed for life a two-part swivel stem for lower maintenance. So there's our 1/2" faucet line. Thanks for listening.
Don't be fooled into thinking that all faucets are made the same! Fisher engineers their 1/2" faucets for maximum longevity and minimum maintenance, providing you with a product that's guaranteed to last.

Hi, this is Jeff. Today I'd like to talk to you about the difference between our 1/2" faucet line and our 3/4". On a 1/2" faucet, we learned on an earlier video that a 1/2" faucet is always defined by its inlets. The inlet of a 1/2" faucet is 1/2" on the inside. Using our close elbow... we always use those so we can fit this 90 degree turn within the 2" backsplash of the stainless steel sink. On a 3/4" faucet, the inlets are 3/4" inside diameter, and with a 3/4" faucet, the elbows are always included with the faucet for easy mounting onto a backsplash. So the elbows go on like that. Now, just to illustrate the difference again between the 3/4" and 1/2", 3/4" and 1/2" - big, big difference. One of the other differences between our 1/2" faucets and our 3/4" faucets is that we put an aerator on all of our 1/2" faucets. This aerator is a 2.2 gallon per minute (gpm) aerator, which happens to meet the standard code throughout the country. Now, if you happen to be chasing any LEEDS points, we make aerators from 5 gallon per minute all the way down to 0.5 gallon per minute. So, depending upon your application, we can supply the correct flow rate on any of our swing spouts for you. A 3/4" faucet, you'll notice, does not have an aerator on it, because it's a fill faucet, and we don't put an aerator on it, because we don't want any restriction at all. We want lots of water coming out of it. The faucet itself, just like our 1/2" line, has got stainless steel seats that are guaranteed for life, and a two-part swivel stem for low maintenance. The big difference of the stem assembly, of course, is that we use a full 3/4" opening through this seat to allow large flow out of the spout. With both these valves open all the way at about 60 pound of square inch of water coming in the back, we're going to get 33 gallon per minute coming out of this faucet. I like to picture a 55 gallon drum being filled up in about 1 1/2 minutes. That's a lot of water! As compared to a 1/2" faucet that would fill that same 55 gallon drum up in 25 minutes. So, whatever application you're using where you want a lot of water to fill something up quickly, you always want to go with the Fisher 3/4" faucet. Some of the applications where you may consider a Fisher 3/4" faucet would be pot sinks, scullery sinks, steam jacketed kettles, large pots, and anywhere where you really want a lot of water to fill a vessel. Fisher 3/4" faucets come in 8" on center backsplash, 8" on center wall, single wall, and a variety of swing spouts that are a full 1" diameter for the flow rate.... from 14" all the way down to 8", so these are designed to fit virtually any application that you might need a lot of water very quickly. Thanks for watching!
