    Great quality product fits perfect in the space. Only issue i have is there’s only a 1/2” fitting on the top part of the tank this makes draining your sink and shower super slow. Adding a 1 1/2” fitting to the top or even a 1” fitting would make this product Perfect

      Hi, we find it best to drain into a lower port for the grey water and using the top 1/2″ port for the vent/ overflow. This creates a natural pee trap and allows the water to flow freely.
      Thank you for the order.

    I’m very happy with my tank

    Fit and installation are a breeze. The brackets do not come with any protective lining between the tank and bracket so I added a rubber liner to the bracket. It would also be nice to have one 1/2″ FITTING on top of the tank for the breather.

    I’m using this on the driver side, not recommended but definitely possible! Quick delivery, great customer support.

    Love this tank. Super easy to mount. I use it as a gray water tank, I would have never thought to empty into the bottom of the tank but it works great.
