I bought this item because I liked the way it brought all 3 plumbing functions of a washing machine into one recessed-in-the-wall box. While it does what it has to do (two quarter-turn valves, one drain line), the flimsy plastic box needs help to prevent it from flapping in the wall once mounted. Here''s what I mean:
The box itself is only 9" wide, and uses very thin (under 1/8" thick) plastic nailing flanges that you can see in the picture of the product. These flanges are VERY flexible, although I doubt they''ll easily break under load. Assuming you mount the box to a pair of 2x4 wall studs on 16" centers, then there will be 14.5" - 9" = 5.5" of span distance on these flimsy flanges. The result is that the entire box easily moves in and out from the wall once mounted. Attaching the water hoses, or the drain line, causes the entire box to twist and turn in the wall, which to me had the feeling of being pretty fragile. I could just see applying a little torque to the water lines and bending the box.
What I did was nail the left side as close to the left wall stud as I could get. I then used Gorilla Glue to glue a scrap of 2x6 to fill the gap on the right side, and then nailed the right side to this 2x6 scrap. This then secured the box tightly against the wall and removed just about all wiggle to it. See my uploaded picture of my arrangement to get an idea of what I am describing.
The second annoying thing about the Oatey box is that the two water valves are mounted deeply (2") in from the front of the box. I mounted the box so that it would be right above my washing machine with the hope that I could use right angle hoses to immediately send the hoses downwards, behind the washing machine. But because of this 2" offset, and the fact that all of the right angle hose connectors that I have found make the right angle turn in under 1.5", then you can''t make such a connection without the hose interfering with the front of the box.
To get around this issue, I bought a
Gilmour 1/2-Inch Brass Double Female Hose Connector 5FP7FH
fitting, and a matching
Nelson Industrial Brass Pipe and Hose Fitting for Female 1/2-Inch NPT to Female Hose, Double Male 50570
fitting, connecting the 1/2" pipe threads together. This combination then attaches to the Oatey hose connectors, extending the hose outlets forward about 1", allowing you to finally attach a right angle hose to the Oatey box and cleanly sending each downwards, not outwards. Of course, you have to do this trick twice, one set of adapters per hose outlet. I also have not managed to find a washer hose pair with right angle connections on each end (only on one end), so I had to buy another brass elbow adapter for this purpose (Camco 22505 90 degree elbow), three adapters per hose! Brass isn''t cheap these days, so these 6 brass pieces more than doubled the cost of my Oatey box project! But what''s a little extra cost when it comes to doing it right?
With these two tricks, the box is securely mounted and I can send attach my Oatey box to my washing machine that sits below it with the hoses heading down, flat against the wall.
I took off one star for the flimsy plastic mounting tabs and another for the deep offset of the water valves that force you to buy a lot of brass extras to connect a right angle hose to the Oatey box.
