Review: Works great for 1 hp pool pump - Replacing an aging 1 hp Hayward pool pump that had a twist lock plug going into a twist lock outlet. New pool pump has a standard 3 prong plug. Got this, hooked it up, runs just fine. The plug that goes into the outlet on this is pretty big, so if you have a weather cover on your outlet you are going to have to bend this to get it to fit. Surprised how heavy duty this is for the price. First impression out of the box is how sturdy and well made it is. Bottom line is it works for my pool pump.
Review: Well made plug - This adapter is just what I was looking for to be able to use a standard plug in the twist lock outlet for my pool pump. It is well made and heavy duty. It enabled me to use an extension cord and supply power for an outdoor tool without any difficulty. Very pleased with this purchase and worth the price I paid.

### ⭐⭐⭐⭐⭐ Fits the bill
*by B***. on August 14, 2022*

I had to replace the pump on my above ground swimming pool which turned out to be a lot more complicated than I expected. Just about every pool pump on the market comes with a standard three prong house plug. Unfortunately (or fortunately depending on how you look at it) my house has an L5-20P receptacle on a grounded, separate circuit as per the latest building codes. The previous owner rewired the old pump with a compatible plug, but I’m not up to that task. If L5-20P is the new code, why do manufacturers build them the way they do? Who knows. But, after some research, I figured out that this little gadget was what I needed. Works great so far! So if you’re replacing a pool pump, this is what you need.
