Training Webinar: Chrome Plated Supply Stops

By Monica Phelan

Chrome Plated Supply Stops are great for this application because they have a wide range of connections including copper solder connections, PEX connections, and compression connections.

A Chrome Plated Supply Stops is a shutoff valve and it would be necessary right before an appliance when you need to turn the water off right at the appliance in an emergency or for servicing. Since water supply lines typically come in through the wall or up from under the floor, the supply stop acts as the shutoff valve accessible right at the appliance opposed to a valve at the beginning of the supply line in another part of the house.


The video below is the Chrome Plated Supply Stop training webinar will focus on a general overview of what these products are, where they are used, and different styles available. 



No Lead Chrome Plated Supply Stops valves are certified to the NSF/ANSI Standard 61 & 372 and the CSA Standard B125.1.  Available in a multitude of designs and sizes to meet your connection needs.


Q&A continued

Will we be adding water hammer arrestors to the washing machine valves?

This is now under consideration. We will advise on any future changes.

Are all Boshart chrome plated supply stop handles and stems plastic?

The color coded washing machine valve handles are metal; ALL other supply stop handles are plastic.

The dual outlet/dual shutoff valves (MULTI TURN) have plastic stems; ALL other supply stops (1/4 TURN) have metal stems.

Has Boshart considered adding supply valves with a Rehau Inlet?

Again, this is something that we are now taking under consideration.

Is it code to have a supply valve at every appliance?

Supply valves are required by some codes. Check the plumbing code in your jurisdiction before installing appliances.

Are the multi-turn valves serviceable? 

This is true. The packing nut can be removed and components like the plunger, stem, packing nut, and handle can all be serviced or replaced. Currently, Boshart’s cannot offer the replacement components but this is also under consideration. That said, the ¼ turn valves have a more simple, robust design that can expect longer life expectancy.

The presentation today will cover a basic understanding of what chrome plated supply stops are; when, where, and why they are used. We’ll go over some key features that we offer in our supply stops here at Boshart Industries as well as what we look for in these products during quality inspections. You may hear me refer the chrome plated supply stops as just supply stops or supply valves in this presentation so just be aware of that to avoid any confusion. They are also commonly referred to as fixture valves.

In this first section we’ll get into just WHAT chrome plated supply stops are. This will be perfect for those of you watching that are looking for an introduction into these types of valves.

Quite simply, these valves are used before appliances, such as sinks or toilets, as a shutoff valve. A shutoff valve would be necessary right before an appliance when you need to turn the water off right at the appliance in an emergency or for servicing. Since water supply lines typically come in through the wall or up from under the floor, the supply stop acts as the shutoff valve accessible right at the appliance opposed to a valve at the beginning of the supply line in another part of the house. Chrome Plated Supply stops are great for this application because they have a wide range of connections including copper solder connections, PEX connections, and compression connections. We’ll see a full list of connection types later or you can view them on our catalog.

Now, let’s get into where these valves are used.

You’ll find chrome plated supply stops in rooms where there are typical water using appliances such as kitchens, bathrooms, and laundry rooms for appliances like sinks, fridges, toilets, and washing machines. Also, the chrome finish on these valves make them much more attractive in those high traffic rooms than other supply valves with, say, a brass or a bronze finish.

There are 4 major designs in these valves, and they are a straight through design, a 90-degree elbow design, a dual outlet or “T” design and a dual outlet/ dual shutoff design.

A straight valve would be used when the inlet and outlet are in line with each other. These are commonly used when the supply line comes up through the floor and go straight up to an appliance.

The angled supply stop would be used when the inlet and the outlet need to be perpendicular. An example of this is when the supply line comes through the wall and needs to go up to an appliance. The supply stop would make a clean 90-degree elbow in the supply line up to that appliance. Really, the key thing to think about when deciding between these first two is that you don’t want the supply line leaving the chrome plated supply stop heading towards the appliance to be bent too sharply which could result in a kink.

Thirdly, the Dual Outlet supply stops are used when you would like two appliances to run off one supply. A common example of this would be hooking up a drinking water faucet and a refrigerator on one line.

The Dual Outlet Dual Shut-off supply stop could be used when you’d like two appliances to run off the same supply but would also like to be able to service one appliance while keeping the other running. This is the only chrome plated supply stop that Boshart Industries offers with a multi-turn design.

Now we’re going to look at some of the different designs of these valves and when they are used. We’ll talk about the difference between a quarter turn supply valve and a multi turn valve. There are two types of operating design for chrome plated supply stops and they are 1/4 turn ball types and multi-turn types.

Most people are comfortable just knowing that for 1/4 turn valves, you only need to turn the handle 90-degrees to turn water on and off and for the multi-turn valves, you need to turn the handle several times before the water is turned on or off. It really comes down to preference of these two actions when choosing an operating design. For instance, some may find it easier to turn the 1/4 turn valves in a tight space than to turn the multi turn valves, which require more action. For those who are looking to know the technical differences, the 1/4 turn ball types operate by turning the handle which turns the semi open ball inside the valve 90-degrees to shut off flow. You can see arrow number 1 on the line drawing pointing to the ball and arrow number 2 pointing to the handle. Aside from the easy operation of the ¼ turn valves, the 1/4 turn design is also gaining in popularity because they are less apt to seize than the multi-turn valves after being installed and left alone for a long time. How they get seized is that there are a lot multi turn valves that have metal stems and packing nuts which, left unused, can corrode or have mineral buildup that will cause the valve to seize in the open position.

A multi turn valve operates by screwing a stem and plunger down onto an opening in the valve. Arrow number 1 on the line drawing is pointing to the plunger, which is pushed down on the opening, so this particular valve would be closed. And arrow number 2 is pointing to the handle and stem assembly. Here at Boshart Industries, our multi turn chrome plated supply stops have plastic stems, which has helped us to avoid the seizing problem.

Boshart Industries offers several models with quite a few connection variations.

The inlets vary pretty evenly from the list there. As I’ve said before, you can see all the connection variations in our catalog. Just a note about the copper solder connections; the chrome plated supply stops we offer have plastic handles that could be damaged when heating up the connection, so we recommend that the handle is removed before heating the valve and then reattached when the connection is complete.

Most of the outlet connections, which is where the water flows out of, are 3/8” compression connections because most flexible supply tubing fits this size. There are a few exceptions to this; one of the straight valves with a 1/2” PEX outlet, all of the ice maker valves which have ¼” compression outlets, the washing machine valves which have 3/4” garden hose thread outlets, and some push fit variants with ¼” compression outlets. A feature on Boshart Industries compression connections is that the threads were made longer to meet the SAE J512 standard. The chamfer that compresses the sleeve was made to that same standard as well. We will go over why this was changed a little later.

Let’s go over some design features that the specialty supply stops offer.

The Washing Machine supply stops have forward facing handles that are accessible from the front for easy operation when they are installed in the washing machine water box. The handles are color coded, red and blue, for hot and cold and the valves have a 3/4” Male garden hose thread outlet to support washing machine supply hoses.

The Ice Maker Supply stops have 1/4” compression outlets to work with ¼” supply hose which is typically used in ice makers.

The Retro-Fit supply stops provide a quick fix solution in the event of an old supply stop seizing up. The valve has a 3/8” compression fitting on the inlet side to thread onto the 3/8” outlet compression thread of the existing, seized open valve after removing the nut and the sleeve. You might see these in places like student housing because it’s an incredibly easy, quick, and therefor cheap fix. They’re great as a temporary solution in any home as well.

Now we’ll go over a few of the items that our QC department is looking for when we receive these supply stops and go over why certain features were changed for the better.

We keep a close watch on the connections of the valves, making sure that they have been manufactured to the standards that they are designed from. This is done quickly with a calibrated gauge for national pipe threads and solder connections. We also have tools to monitor the alloy of the material to make sure that the correct brass alloy is being used in the valves. The R&D team here at Boshart Industries has engineered gauges that can quickly test push fit connections. As I had mentioned before, we changed the compression connections to meet the SAE J512 standard. This was changed to accommodate the use of flexible plastic supply tubing which would cause the compression nut to bottom out before making a proper seal. The threads were made longer and the chamfer for the sleeve was made to the new standard which has made sealing to plastic supply tubing effortless. R&D has designed gauges that quickly test the compression ends to the SAE J512 standard. Something else that we inspect is the disassembly torque.

We’ve created a Boshart specification for the force it takes to break the seal on the body joint which is 20 ft/lbs. This is particularly necessary in the off chance that a compression nut is seized and while trying to remove it, the body joint seal is compromised which would mean the entire supply valve would need to be scrapped and a new one installed in its place.
