Just curious, but why would you rate Stenner pumps over a Hasa Liquidator. Is it because you can run from a larger chlorine source requiring less manual addition? The benefit to the Liquidator is it keeps some mineral salts from the bleach out of the pool as they are precipitated in the bottom of the liquidator tank. It also requires no electricity, is cheaper, and is made of simple cheap parts if any maintenance is ever required. But as it has a lifetime warranty on all parts, this should not be an issue. I got one this summer and am curious if it was the best decision. So far I have seen no real downside.
