Low or no Pressure on soap, however High pressure on Rinse

[Nknjeim]

Self Serve Carwash with Coleman equipment.
Too many things broke down due to freeze we had last week in Texas...
In one of the bays, I have a low or no pressure on soap (usually high pressure) however high pressure rinse is still working normal.
Anyone can help?
Thanks

The check valve under the tank is stuck closed.

Isn’t it the same valve that feed high pressure rinse too?
I am getting soap but no pressure

Rinse is fed by a solenoid. Water for soap comes through the check valve under the tank.

Check for a leak, if it is spurting, it is probably because air is in the line. Check if air is in the line, and check for leaks. It is also a good idea to call for maintenance if the problem is deep in the machine or you don't know what the cause it.

Agree with Mep. I am in Texas as well running 3 JC pump stands and already replaced 3 check valves because they froze and got shot. Along with that you may have replace the seal kit in the pump as well. I had similar problem replaced the check valve then had to replace the seal kit.
