Single Union Ball Valve - Slip X Slip Information

Note: While this fitting has a union, it is not designed to seal/hold water when the union is removed. The union is primarily for maintenance of the ball valve.

**Variations of this product can be found in many online stores. The version we carry is of the highest quality. Although this item is eligible for price matching under our Low Price Guarantee, please be certain the product you want to price match is the same make and model.

Hate it

Comments: You can't hold water behind the valve and disconnect the union. I thought that was the whole point of having a ball valve in front of the union. If you disconnect the union, the ball valve comes apart and doesn't seal.

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.

Horrible design

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!
