Laserwash 4000 Undercarriage Issue

I noticed that occassionally my undercarriage is struggling to get to full pressure. I think it is happening when there hasn’t been a wash for a while. I let the wash sit last night for about an hour and then ran through and the undercarriage took about five seconds to get to full pressure. I ran through again immediately and it worked fine. I’m guessing that air is getting in the line, but not sure where to start looking. Thanks in advance for any guidance.

The water is draining from the pipe/hose while it is idle. Installing a check valve in the line as close as possible to the UC manifold will prevent the water from draining out, getting you a nearly instant response.
