    I forgot when filling it with water to have a way for air to escape - I didn’t notice and this thing was huge - maybe 20% bigger and hadn’t popped.

    I instantly removed the water and air was released and the tub went back to shape. Huge win on the quality. Wish there were more options for where the inlets are but it’ll do.

    Fittings badly placed
    Reviewed in the United States on July 8, 2020

    Full content visible, double tap to read brief content.

    The fittings should be at least one on top and one on bottom, so you can fill the tank to 100% capacity and discharge 100% of the water, Instead the fittings are on the sides, so you loose 10+10% of usable capacity (unless you drill your own fittings, but how do you bond HDPE?)
