Any problem with installing check valve in high pressure to stop drips?

[Buzzie8]

I noticed that most of the drips from the gantry are coming from my high pressure tips in my boom arm causing problems with my blowers drying the vehicle. I want to install a check valve somewhere near where the high pressure hose meets the boom arm manifold. I noticed that all my other check valves are on low pressure functions. Maybe I only need to do it on my spot free because this is my last pass. Can check valves be installed on high pressure? Also, where is the best place to install? I am running Jim Coleman water Wizard 1.0

Are you talking about the blow down cycle at end of wash?
if so I would like to know the solution also, I have spoken w/coleman and they say there is nothing we can do too control this???
I have tried to change it in the red lion with no success.

I am assuming you want the blow down cycle to last longer. I notice water dripping out of the tips on the far left of the boom after the blow down cycles. I think that if I put a check valve in the spot free or high pressure hose that feeds the boom manifold it might stop the drips. I am not sure how a check valve would react to the blow down or the high pressure while they are operating. What do you think?

A check valve on High Pressure works fine I used to use them on a old
Mark VII Rotoclean. Just make sure they are the same size as Your HP hose.

In order for it to do what you want, it needs to be a high cracking pressure check valve. It won't take much, 5 psi or so, to prevent the siphoning.

Isn't there a solenoid valve on the drivers side of the boom that opens when you are done rinsing and bleeds the HP line? I'm gonna look at my 2.0 today to see how it's set up. I have drip problems from water accumulating on the top underside of the gantry. A combination of mostly spot free and HP rinse water from the side oscillating nozzles.

Buzzie, Before installing a check valve, look at the 90 degree high pressure swivel that connects to the end of the boom that connects the hp hose.
If this swivel if bad it will let air into the hose when the pressure if off and therefore allow the water in the manifold to drip out.
If this is a problem that just started this could be one of the problems.
A shot in the dark anyway.
