If the sucktion vaves do not close, also water keeps on circulating. Also there could be a fault in the sucktion valves. In this case change the spill valve with a new one. If when the trigger is pulled and the bottom part of the spill valve does not close, then water keeps on circulating and hence no pressure. When the trigger is released, the spill valve compresses to let water circulate from its bottom part. When the trigger is pulled, the spill valve is in normal position. This is sometimes refered to as the Spill Valve. 92 Answers SOURCE: Dear dennis_partr, In general all pressure washers have a control valve.Original replacement parts from KEW through our European and Asian Parts Service.
