Hello, I recently replaced the float/valve in my auto pool leveler. Im having problems adjusting the float level as it seems to have to be angled very high to be at correct pool water level. The arm of the float is under the valve opening, so when it’s angled so high, it touches it. Can I install it upside down? Does the float arm need to be loose because if it’s tightened it won’t move with the water level?
