Is there a better dump valve?
I have cable operated Valterra/Bladex dump valves that failed to operate. I know that the cable type can be troublesome, so I explored the reason for the hard operation. I found the cables were not ...

The usual cause of debris in the valve body cavity is the practice of LEAVING the valve OPEN while camped. This allows the slower moving liquid/solids to fill into the normal gaps in the valve cavity. When you dump a tank with liquid in it, the rush of debris/water is enough to keep the debris from settling in the valve cavity. Once the debris is in the cavity, there is NOTHING to do except pull the valve and manually clean it out. Cable operated valves, it is easier to clean out once the valve is pulled. Rod(Handle) driven valves are harder to clean because the odds are the debris has been FORCED into the valve body because you can push harder and the cable will just flex. But, backflushing or trying to install a chemical will not get rid of the debris in the valve body. You have to dig it out with a screwdriver. Doug
