I always have problems with my water tubes every year. Are the Aqua Blocks any better?
Reply
The Aqua Blocks are made to stay flexible down to 50°F below zero. They will not crack or leak even in the coldest weather. The Aqua Blocks come with a secure snap-lock cover and are U.V. treated to last for years. They are available in a 6 pack or 12 pack as well.

(4 out of 5 stars) Better on a warm day.

They serve as advertised, but durability is limited. The plastic becomes stiff and prone to damage or leaking when it is cooler. Probably better if installed or removed on a warm day. Fortunately the price is not too bad, should some need replaced.

(5 out of 5 stars) Dog Proof

Cons: Hard to open in the spring.
We've gotten cheaper ones. There are more expensive ones. These do the trick though. Even in the winter when we've had other tubes become brittle and easily punctured by dogs running around out back—these held up all winter.
