Midline Valve 822M223 Premium Brass Full Port Ball Valve 1 in. Compression Connections, 1

The valve seems to be solid in construction. The walls are thick and the ball and handle open and close freely.I removed a 1 inch gate valve that had failed. I like the quarter-turn ball valves. They are either open or closed with one easy motion. The compression fittings allow for solderless connections in areas where water is present, making the use of a torch not feasible. If the compression fittings are tight, there will be no issue with leaking.

I am going to use this valve when I install a new shower valve in my granddaughter's bath. I have used this compression type valve before. Very easy to use, no need for solder. Just cut in the copper tubing and this valve installs easy. Tighten the compression nuts and turn water on. This valve was the most competitive price after searching several pluming suppliers. And the quality is equal or better than the others I have used in the past.

Purchase 3 of these. Replace old multi turn values by installing before the old values. Worked great. Much easier no soldering. Will be purchasing 3/4" and more 1/2" values. Good value because there is no rubber washers that need to be replaced the next time you need to shut the water many years later.

Well cast, smooth operation, and easily installed.

Fast ship..havent installed it yet

At first I though I was going nuts. I purchased and installed several Everflow 1/2" and 3/4" ball valves. Some of the 1/2" valves required an inordinate amount of tightening in order to fully seal and two kept dripping.They seem to be made well enough but finally I discovered the problem is that they just do not fit the copper pipes very well.It could be that the rings are too thin at the leading edges or (more likely) the nuts are a bit too big where they fit around the pipe, or perhaps both but the end result is the rings actually start to slip through and past the nut so no matter how tight the nut is, the connection still leaks. (See the image)I will need to remove at least those two and replace them with others that fit properly but my concern is that the rings will be so compressed that they will not come off the pipes which will make removing near impossible.NOT A GOOD DAY !!!Eventually I will look into returning them but I'm not there yet.(Edited Oct 5)Spent a good bit of the day Sunday fixing part of the issue and was more right that I wished.Because of the over tightening, the copper pipe was compressed which indeed made removal near impossible. Ended up having to cut out the valves and solder new sections to make up for the length which really set me back. One of the main reasons I selected compression fittings for this job in the first place is the work space is inconveniently located in the crawl space with lots of wood and insulation nearby, making work with a torch problematic.At Home Depot I purchased new rings and compression nuts (which actually fit the copper pipe) so for one of the repairs I used an extra Everflow valve (I originally purchased 5 but one came incomplete so I used it now). That extra is installed and seems sealed. For the second that is still jammed on the cut off section of pipe, I simply bought a replacement at Home Depot which fits the pipes just fine.I am still concerned about the remaining two 1/2" valves but have not looked under the floor yet today... The 3/4" valves still seem OKWill be calling the manufacturer so more to come...Edited Oct 6thThe Home Depot replacement valve is fine while the Everflow valve which I put in using the new nuts and rings is better than the one it replaced but it is still dripping so I guess I will cut it out again and buy a new valve from HD. This is getting really old but its become an interesting research project..As I noted earlier, one of the valves shipped incomplete. Amazon (great service once again) sent a replacement. It came today.Thinking about what could possibly be causing the valves to not seal 100%, it occurred to me that perhaps the seat where the ring presses against the valve is malformed or not well machined. Have a look at the two images (IMG _1325-rough and IMG_1332-polish) 1332 is the one that just arrived. The seat and the barrel are not perfect but they are clearly quite smooth while you can easily see the machining marks in 1325. Definitely not polished. This could also be part of the issue.As a follow up to the nut size issue, see (Pipe gap with two nuts.jpg)The two pieces are relatively uniform size wise. As you can see, the original nut on the left allows a .025 wire gauge to fit between the pipe and the nut while the one on the right would probably not even let a piece of paper fit between the pipe and the nut.

I went to install this valve and the Compression Ferrell is Undersized for 3/4” copper pipe. The size wasn’t even close, even tried sanding the pipe with emery cloth to slightly reduce the diameter however still didn’t fitI had to purchase a new compression Ferrell from my local hardware store which fits fineOther than that issue the quality was excellent no leaks, cracks, etc
