Cleaned the blaster and got it all set and leveled and now it keeps overflowing bubbles. I have it going back into the sump but last night I had the drain tube going into a container and within 30 min. it has bubbled off 4 quarts of refill water that is why I set the tube to drain back into the sump. This morning it is still bubbling over. I have closed the red valve completely and still bubbles. As soon as I put the drain tube back into the container it will fill it and drain the sump dry. Bubba
