Comments: Had limited space under cabinet for plumbing external return pump. Ball valve/union cut down on amount of valuable space used. Heavy duty construction, and most of all no leaks.

Comments: yes, read the note. do not shut the valve off then disconnect the union. the ball pops out and i put about 20 gallons of water from my sump on my carpet.

<br />worthless product.

Comments: Found out the hard way that if you actually use this the way it was designed you will get water everywhere! If you close the ball valve and then try to disconnect the union and there is any pressure (like water or gravity) then the ball comes right out of the ball valve. It was designed with a removable ball, but the problem is that the ball is designed to come out when the valve is closed and you disconnect the union!
