Unmovable union fittings


Finally got around to changing that old laundry faucet. But of course, ran into a problem. I cannot get the union fittings to move at all highlighted in the picture.

And before anyone says "I need to remove the nuts below first." I did that already and got stuck afterwards. This picture was taken after I put the old faucet back on. Then I thought I would just reuse the old unions and nuts since they weren't leaking and so tight, but no! The hot side fits on the new faucet, but not the cold side.


Is there a special tool I should be using? I've tried pliers and vice grips already. Or am I going to have to remove more pipes just to get at these unions? Not shown in the picture is a pair of shut off valves for the washer hoses. I can take more if necessary.

With the union nuts loose, two 14" pipe wrenches will do it to it if you turn the correct way. Be aware the pipes will be getting longer by 3,4 or possibly 5 thread pitches as you unscrew.


Pliers, channel locks and vice grips are a sure sign of amateur plumbers.

#1, So far your using the wrong tools. Vise grips are going to crush the fitting and there's not enough leverage.
#2, 100 % sure your turning them in the right direction? Should be turned from left to right.
If you can get that spout off it would give you more room to work.
Try using a real open end wrench. May have to give the wrench a tap with with a hammer to break them free.
If that does not work may have to go to about a 14" pipe wrench.
Are those Pex supply lines?

Too lazy to change more of them. But get this, the guy I talked to yesterday at HD told me my channel locks would be enough. Sure enough, I took all of your suggestions and brought 2 pipe wrenches and they came right off with ease.

Smart person, ignored the big box store and listened to those here.

Maybe they were short handed in plumbing that day and moved a guy over from the crafts department.
