To echo a post from 2016.....Got delivery of a brand new Bullfrog A7L last week. Everything went smoothly, got it hooked up to electrical, filled it up, heated to 100°.
Then on first test, I notice that on 1 side, the jet are weak even on highest speed. On that side, 1 corner seat emits a loud noise as soon as there is pressure on it (someone sitting in that seat). It makes a strange loud buzzing noise and vibrates. I switched the JetPacks a couple of time but same issue with all of them in that seat. So far, only 1 side (pump1) with 2 jetpacks is working fine. I've eliminated the possibility of it being a jetpack issue since the same seat has the problem regardless of what Jetpack I place in that position.
Any recommendations or experience? Its a brand new 2020 Bullfrog A7L.
Thanks!
