3M Filtrete 3US-PS01 Under Sink Filter System Installation Video Transcript

Hey everyone, Tony the Filter Doctor here, and welcome to our installation series. Today we’ll be installing the 3M Filtrete 3US-PS01 under sink filter system. This is a system that does not require a separate dedicated drinking water faucet. It filters water at a rate sufficient to supply the regular kitchen faucet, and we’re going to install it for you, right now here today. Watch how easy this is. In the box you’ll find a hardware packet with a variety of fittings and some screws, the valve head assembly with a mounting bracket attached, the filter cartridge, some 3/8 inch polyethylene tubing, and a set of instructions. The first thing we need to do is turn off the water supply of the cold water line. Since we’re attaching this to the cold water line, I’m turning this valve clockwise, all the way snuggly, now the water is off. Now that the water is turned off, I need to remove this 3/8 inch braided line. Using a wrench or an appropriate sized plier, loosen this nut from the valve. Once it’s loose, you should be able to remove it by hand. It would be perfectly normal for water to drip out of here, although it doesn’t always happen. Next, locate this fitting in your hardware packet. One end are male threads and the other end is a quick-connect fitting. Now that we’ve removed this from the valve mechanism, we need to attach this connection piece directly to this. Simply screw it into the end and then hold the one end with a plier, and with a 5/8 inch wrench tighten it the remainder of the way. Now take one of the two blue pieces of 3/8 inch polyethylene tubing and insert one end into this quick-connect fitting. It will sort of snap into place. Now locate the compression fitting hardware from the hardware packet and take the other piece of 3/8 inch blue poly tubing and take the brass 3/8 inch fitting with the threads toward the end of the tubing and slide it over the tubing. Then take the ferrel with the thin tapered end toward the end of the water line and put it over the tubing. And then lastly, insert the tubing insert into the end of the tubing. Now we can take this entire assembly and attach it to the valve mechanism. Now we’ll take the entire assembly and insert it into the valve mechanism, and then attach it. Hand tight as far as possible, of course, and then with either a plier or a 5/8 inch wrench, tighten it the remainder of the way. Now with the plumbing out of the way, we can focus on the mounting bracket and where we want to locate the system. You may want to avoid mounting the system on the back wall of the cabinet for a couple of reasons. One, the backs of cabinets are typically thin and flimsy. If you know that you have a sturdy back then that might be a fine location. But the second disadvantage is you have to climb all the way through to the back of the cabinet every time you change cartridges. It may not be the most convenient location. I prefer to mount my filter systems on the side wall of the cabinet, somewhere mid-way between the front and the back for easier access, and because the side walls are typically thicker and can handle the screws necessary to support the weight of the system. So, knowing where I want to go, I need to measure the height necessary for the bracket, and it’s important that I get this right because this type of system needs about 2 ½ to 3 inches of space below the cartridge for cartridge changes. You see, when I remove the cartridge, it needs to drop down out of the way before it can be fully removed. If I had it mounted too close to the bottom, I’d never get the cartridge out. So a minimum of 2 ½ to 3 inches of space beneath, so I simply need to know the distance from the holes on the bracket to the bottom of the cartridge, which looks like approximately 12 inches. So I’m going to add another 3 to that and I’m going to mark my line at 15 inches from the bottom of the cabinet. I’m going to do that now. Now I’m going to mark the holes for the bracket itself. Now using a 1/8 inch drill bit I’m going to drill a couple of pilot holes. Now I want to leave the screws out about ¼ of an inch so that I can slide the bracket over and then I’ll further tighten them the rest of the way. Now we can attach the water lines to the quick-connect fittings on the valve head; this is super easy. The lower of the two quick-connect fittings is the inlet line, so we obviously want to use the water line coming from the valve mechanism. And again, these quick-connect fittings are super easy, simply stick the water line in and it pops into place. And that’s it. And then the outlet line is the line that we attached to the water line going up to the faucet. Again, it’s just pop it in and that’s it. It’s not going anywhere. And now we can install the water filter cartridge. So here is the filter cartridge, simply screw it in place and we’re done. Folks this really wasn’t just the magic of television, this system really is easy to install. Again, it’s the 3M Filtrete 3US-PS01, an under sink filter system that does not require a separate dedicated drinking water faucet. This is our installation series, and I’m your host Tony the Filter Doctor. Thanks for watching.
