we had to take apart and reassemble our hayward multi-port valve and after putting it back together, i noticed we were losing water during Filter. So we took it apart again and i added RTV to the spider gasket to stick it to the bottom of the valve and I added tube lube to the top of the gasket. Now in the filter setting, we're not losing water anymore, but I noticed that we lose water during Rinse. I thought during Rinse, the water is just suppose to swish around the filter. I thought we only lose water when we set it to Backwash and Waste. Is that right?
