no soap on high pressure

no soap on high pressure ..hypro 2410 .. seems like its actually putting water in the soap tank ,through the check valve

There are multiple ways to get soap into your high pressure line. Hard to diagnose without knowing your setup. All we know right now is that you are getting no soap when on high pressure, but are you getting any high pressure? Also, something backing up into the soap tank, but are you getting high pressure? If so, and assuming the soap is drawn in with a check between the pump and the soap tank, then you might be onto diagnosing your issue. Replace the check.

The typical car wash setup is to have open tanks for soap, wax, and hot water, with rinse fed from a solenoid at city pressure. If this is your case, you may have a check valve on one or more bays that's bad. The check valve will be at the pump where the soap and wax lines come together.

Have you checked this strainer in your mixing tank?

I have 2 SS bays ,one of the bays and pump dispense soap .during wash ... The new pump does not put soap ot with wash..They both use same line ..and check valve from tank. They each have a solenoid at the pump to let soap com in to the lines.

Have you checked the solinod to make sure it has power and opening no trash in the solinid or line. Thats a good place to start. (Also since you recently changed the pump make sure you instailed the check valves in the right direction.)

Happened to us with new equipment last week. Had to take the solenoid apart, wash parts in hot water, and use an air can to clean out. We also keep two spare Kip replacement kits (from KR) so we can swap the parts and clean when we have time.

I had a similar problem in one bay and it turned out to be a bad rinse solenoid which allowed the pump to pull rinse water rather than wash water/soap. It may have been getting some of both, but soap was so dilute it was useless. Rebuilt valve and problem went away.

Good luck and let us know what you find.

Still no soap .. The setup is . the water source from stainless tank (1 Inch gravity flow to the pump ) and 3 solenoids
inline before the pump .. 1 for clear coat ,1 for pressurized from city -hot water and 1 for soap(gravity from check valve in stainless tank).. when soap wash is selected I do get hot water but no soap.
when I disconnect the hot water solenoid I get soap but no hot water .. Thanks, for all the help

Buy a replacement Kip from KR ($16), swap it for the one giving you and issue - then clean the one removed at your leisure. We took ours apart to clean and remove the junk causing us the issue in the solenoid.

Are you saying the hot water is pressure fed?

YES, From On Demand

pressure fed water won't draw soap, it would have to be gravity fed.

 

[Flamingo]

The main water is gravity fed on all functions ..The hot water is fed from a solenoid valve. so the hot pressure water from the
solenoid is overriding everything ,keeping it from pulling soap thru the other solenoid? . what's strange is the soap and hot water was working before I swapped pumps.

 

[Main Street Carwash]

Maybe the new pump doesn't draw as much suction. Is the same model as the previous one? Can you throttle the hot water inlet down any? I'm not sure how soap could be drawn off of a gravity tank into a pressurized inlet unless the suction of the pump is overcoming the flow and pressure of the inlet creating a lower pressure than the soap inlet pressure. Maybe someone here with more experience than myself will chime in here and help.

Thank you, I think you might have nailed it .. The new pump draws 5 gallons per minute /the old one draws 8 gallons per minute..I might try to throttle the hot water down some .

What kind of pump did you remove and what kind of pump did you install? On my setup the only way I can get the pump to draw chemical is to reduce the incoming water pressure with a Generant water regulator and use a DEMA 203C injector. Both my Hot and Cold water is fed with reduced city water pressure.

replaced a Hypro 2414 with a Hypro 2410
