Pool Dial Diverter leakage

I recently relpaced a pool dial diverter after the spring broke in the original. Now I am getting some water going to the return line while the dial is on “filter”. Any ideas why?

Hello MuthNathan - Water leaking from the backwash line is usually the sign of a bad spider gasket. What is the make and model of the valve?

I replaced the spider gasket when I replaced the spring. Valve is on a Jacuzzi 250L.

There are a couple different valves used on the 250L. Which valve model do you have and what was the part number of the spider gasket you just installed?
