Jojo water tanks fails on design and support

JoJo Tanks sells tanks where the water inlet fitting has no retaining ring or nut on the inside. The fitting simply plugs into a hole in the tank. That’s it. No mechanical lock. Nothing securing it in place. It’s like putting a bolt through a hole without a nut and hoping for the best.

I assumed mine was defective, so I checked multiple retailers. Every single tank was the same. The top inlet pipe pushes into a fitting that just sits in the hole. There is absolutely nothing preventing it from pulling straight back out.

I tried to make it work by gluing the fitting from the inside. Eventually it failed, pulled out, and my inlet dumped thousands of litres of water. Completely avoidable.

When I contacted JoJo, the response was frankly ridiculous — claiming the design is “to help installers.” That explanation makes no technical sense. A fitting that can fall out under normal conditions is not an improvement. After I challenged the explanation, I was ignored.

Even the sales staff at Chamberlains acknowledged the problem. They said they sell generic retaining rings because so many customers complain about this exact issue — they were just out of stock at the time.

Releasing a product with such an obvious design flaw is inexcusable. Save yourself the frustration, the water loss, and the unnecessary workaround. Buy a competing product that uses a properly secured fitting
