It is possible the restriction is in the tank itself.I have seen build up restrict the spray ports in the tank and causes this fault here in lots of cases.If the hoses all look o.k. and the anti siphon is installed correctly I suspect this is the cause here and it may need to be removed and manually cleaned ( by a professional in a safe and sanitary way ) to then clear up and resolve this issue here.In a worse case scenario the tank may need replaced.

Are you sure that the valve out of the tank is actually open? It may be that the blade came loose from the handle or cable. This happens more than many would realize. Or I have seen cases in my shop where the plastic disc that was cut out for the entry of the black waste pipe was left in there and got washed down to the mouth of the tank and blocked the waste and water from exiting the tank. Depending on which chemical you use it can be just a large amount of undigested waste that has accumulated at the mouth of the tank. I use Happy Camper Extreme Cleaner in my shop for all my customers and that is the best for cleaning and breaking down any debris. Available on their website or Amazon if your dealer doesn't stock it. And then you can try using a clip on waste valve and HydroFlush unit so you can back flush the tank some from the hose connection. That would help push anything back from the mouth of the tank and it is clear so you can tell what is coming out once you open up the clip on valve. Most RV shops sell these or numerous companies online. Those would be the steps I would take in my shop here. If the valve is broken, that will become apparent quickly and then some steps taken to repair or replace it. Taking some of the underbelly down is needed to access that area. Hope that gives you a place to start. I wouldn't judge our service by one reply. I have successfully assisted over 11,000 customers over the last 8 years and many are repeat customers.
