My returns have had bubbles coming out of them and there are large bubbles visible in the lid of my filter pump. My PB installed a jandy valve to allow some of the water exiting the filter pump to bypass the filter and heater and return directly to the pool/spa. Is this normal? I haven't been able to talk to them so maybe they are just trying to figure out where the bubbles are coming from?
