      Q:Can it be used upside down is that also a drain on top

      Answer This Question

      A:  The box may be turned upside down to when installing, but the drain should remain on the bottom. If you do turn upside down, make sure you move the valves. For further questions, please give us a call at 888-229-2874.

        A:  No, it is not designed for use upside down. Mike

        Q:The photos seem to show that the cold water handle hits the side of the box when opened. Can you confirm or deny this? Does it impede the use of that control? Does the hot water control hit the side when closed?
        by|Sep 20, 2022
        1 Answer
        Answer This Question

        A:  Both the cold and hot water valves do not touch the side of the box when opened or closed.

            Best washing machine outlet box available
            This Apollo expansion pex (or pex-a) washing machine outlet box and included valves are great quality. The valves that come with it are solid and feel like really high quality. I installed a competitor's (start's with a U) box/valve kit where the valves were loose and leaky, and replaced it with this Apollo one - night and day difference. My only complaint is that the brackets felt a little flimsy but I still think it's a five star product. I've had it installed for 3 months now, it is solid.
