Note that this combination product consists of a regular Sharkbite angle-stop shut-off valve, plus a connecting supply hose to a toilet - except that, distinctively, the joint between the valve assembly and the connector hose isn’t the usual compression connection made in the field, rather it is a permanent connection made in the factory. So it pretty much eliminates one possible failure point, one possible failure mode, by making that join permanent in the factory. And that’s pretty much all that’s distinctive about this combination product. The valve component is Sharkbite’s, and the connector supply hose component is Fluidmaster’s, both about the best in their respective businesses. So you just know this combination device is really well made. And so too it has just got to be a really great idea, right? Well, I sure thought so - for about the first hour after I first saw it on Amazon, and got enthusiastic and excited and carried away and ordered one. Whoops! After about an hour of living with the idea - just after the easy opportunity to cancel the order expired - it came home to me that this device is actually a mistake, a bad idea. It’s not like the wedded combination of the two components saves you noticeable money. All it does for you that any combination of shut-off valve and connector supply hose doesn’t do is it eliminates the risk of failure at the join between the two main components. The problem is that that join is NOT a likely failure point. The overwhelmingly likely failure point in this combination device is (drumroll please!) the big plastic nut that joins the connector hose to the toilet fill valve. And when that big plastic nut fails - and it will eventually fail, and almost certainly way before anything else in this assembly - you will have to replace not only the ~$6 worth of connector hose, which by itself is relatively cheap and quick and easy to replace, you will also have to replace the permanently-joined ~$10 worth of Sharkbite angle-stop shutoff valve, which, being a Sharkbite, is also pretty easy to replace, but still a lot more work and cost than just replacing the connector supply hose. You’d be almost certainly much better off getting a separate angle-stop shut-off valve and a connector supply hose. This combination plumbing device is kind of like buying a table lamp that comes with a light bulb permanently soldered into place: That eliminates a possible failure point, but an unlikely and easy-to-fix failure point - just screw down the light bulb as necessary - and when the inevitable happens, when the light bulb burns out relatively soon, it forces you to dump and replace the whole lamp. Bad idea. So don’t buy this combination plumbing device, there’s virtually no plausible scenario under which it’s an overall winner for either purchase cost or labor. Instead buy a separate Sharkbite angle-stop shut-off valve, plus a good connector supply hose. This way, when the plastic nut to the toilet inevitably fails, you only have to replace the connector supply hose for around $6, can leave the angle-stop shut-off valve in place. Best of all, don’t buy the Fluidmaster connector hose either, or any hose with a plastic nut attaching to the toilet, because that plastic nut is the overwhelmingly likely failure point in that arrangement. Instead buy one of the few available toilet connector supply hoses that still comes with a brass (instead of plastic) connector nut to the toilet, like the Everflow 27413-NL is the one I chose, seemingly available on Amazon as the Highcraft 49635, crazy inexpensive too. This way, with no plastic under stress, the whole connection should last decades. Meanwhile, I reckon I’ll rate this combination valve and hose product 3 stars, right in the middle of the scale, because I’m sure it’s quite well made and well-supported, but you really don’t want it!
