When I first turn on my pressure cleaner after it has been off for a day, a large amount of air spills out from between the wall and the cleaner fitting/regulator. It takes about 30 seconds before you start to see the bubbles after the cleaner pump comes on and stops after about a minute. All the connections at the pad seem ok. My theory is that after several hours with the SWG on all the bubbles are being diverted up the cleaner suction line and are trapped it the U. When the cleaner first turns on, it pushes all of it out. Everything is stable after few minutes and it can't be repeated until its be off for a long while. My pb didn't seem to have a clue and was going to send out a tech. Has anyone seen this issue?
