Laser 4000 undercarriage

[Ontario Car Wash]

Hello,
Noticed water coming from under carriage randomly when arch is spraying. I assume there shouldn't be any?
Thanks

How much? Probably a lexair valve issue. Do you have a rebuild kit?

 

[Ontario Car Wash]

Not much little soapy at times
I originally thought it was just the weep being on
I think it's the weep check valves are bad
No soap in rinse tank

I have a check at right before my undercarriage manifold. If it is bad, a little water can pass through.

Ya it's not much we're​ is that check valve in the bay ? Or on the stand?
I have one in the bay just before the undercarriage is that the one u speak of.
Thanks

Question should the water be soapy or is a low pressure solenoid also not closing ��

That's the one. It should be clear rinse water. So it might be a check valve in the manifold
