For 3 days we are facing OP starvation, the distributor engineer found that there always air bubble inside OP tube. They already replaced electrovalve and butterfly valve, also take out the bubble, but seems air bubble keep appear inside. HP engineer came yesterday, but didn't help much. Is there alternative action to maintain air bubble free of OP tube? Or may be simplest way to detect and take out air bubble from tube? Thx, Rensi
