hi all,
we have a lavac head which uses a henderson manual pump. the henderson pump is very similar to a whale diaphragm pump. the pump is mounted so the output joker valve is vertical. this valve then takes the brunt of the discharge since residue will gather around it. it also means it's the first part to fail. disassembly and cleaning works for a while but the valve physically deteriorates and need replacement long before the input clapper or diaphragm. the valve id unique sice it is held in place by 4 screws that hold it in the output port. the rebuild kit costs about $75. so in reality my joker valve costs about $75.
my question: 1) does anyone know a source for just the joker 2) is anyone aware of a replacement which is readily available?
