Either or both inlets' water is pumped to either or both outlets.

One or both can be used, same with outlet ports, makes for more installation configuration variations. Example: you could use one inlet port for water supply, the other for the regulator bypass return.

Some units use an unloader. When water is not flowing out of the system the pump is "unloaded" and the gauge will read zero. When you trigger your cleaning tool, pressure will build and show on the gauge. Be careful turning the pressure adjustment knob when unloaded, it can cause a spike when...

Having the orifice swapped would cause the issue you are seeing. The water would circulate from the heat exchanger at a much higher rate than designed. The water box would heat up quickly, the water going to the pump would boil , acting like an air leak. (vapor). I have seen the hoses reversed...

Do not wear fear on your face.

Keep the unit stock. I have professional advice if you would like. It looks like a clean old machine. 25 yr technician here. Ask away. WWG1WGA

I'm glad to hear that the issue seems to be solved. A bit of pulsation is normal with chem systems, and a bit of air will be trapped on the cat pump side of the diaphragm. It should work it's way out.

You're welcome. Good to hear that you're busy.

Exactly. There needs to be a path for the pulse to reach the chem pump.

The Cat pump valve plastic spring " cage" needs to be drilled out for the chem pump to work properly. If the pump was rebuilt, including valves, this small but critical detail is often overlooked.

You could try replacing the overheat shutdown relay. It is the relay with wire colors yellow/black and black/blue included in the connector. Having the pressure pump switch off allow the unit recover is an indication of a possible fault in that circuit. The relay is easy and inexpensive to...

I have seen blower belt slippage often described as "bogging". The blower is the majority of the sound the machine makes. When the belts loose grip, the blower slows, and gets quieter, you will hear the clacking engine sound, it's still running full speed. Once you take the load off of the...
