I have a new ecostar but the strainer basket never fills up and now it is losing prime and when restarted it take forever to autoprime.
I'm changing the skimmer and maindrain valves as pump could be sucking air from these as they are kinda old. Also bypassing an old heat pump to see it that helps.
Is there anything else I need to look at? I already cleaned the filter. Is it normal for the water to never fill the strainer basket?
