Check it over before buying

Would Recommend

I installed it everything was fine until we got a very bad rain storm and I came home to my house with water all over the place. And no it wasn’t the pumps fault.

Cheap but fragile and noisy.

It fit and was cheaper than others, but is noisy (clunks when closing) and the first one cracked within a week.
