Pressure rupture discs prevent over-pressurization damage to the pump and are essential on every jetting unit. Always use correct color rupture discs for proper pressure protection, and never use a substitute such as a penny which often results in pump damage.

FAQ

Can I change the gun mode on my sewer jetter to operate at 4000PSI?

Yes, call your USJ rep and they can walk you through the steps to adjust this setting.

Do I need an unloader valve?

No, because this gun has the dumping feature, it does not require an unloader valve.

Water is coming out of the end of my dump gun even when I pressure down. Is that ok?

Yes, the dumping feature means that when you release the trigger of the gun, instead of dead heading the water pump, the water is relieved at low pressure out of the end of the top barrel on the gun. This protects the pump against over pressurization.

Why does my engine bog down when I use this dump gun?

If your engine is bogging down, you likely need to open your bypass valve to divert some water back to the tank since the gun is only rated for 8GPM.
