I want to install a gauge on the discharge side of my pump. I want to use the gauge to calculate flow. My issue is that I have a Hayward SP1486 union going from the pump to the multi-port valve. The SP1486 is a 10" long lexan elbow. The valve end is a self aligning union and the pump end has a compression fitting that threads into the pump.
Has anyone tapped this for a 1/4" NPT thread? Does any one know if it can be done?
