This box has 2 buttons that push air through tubes to control an underwater treadmill made by Hudson Aquatics. It’s mounted as shown but it has picked up water and I have to replace it as water has made its way into the tubing. It arrives next week. I have decided to mount it on the pool deck, completely out of the water. Does anyone have any suggestions on how to mount this? I’m thinking some type of stainless steel or clear plastic that could be screwed into the coping and hold the box firmly just about 6 inches above where it is now. I have an automatic pool cover so I can’t have it sticking up above the waterline out in the pool water.
