An education on replacement pressure washer pumps. ETS Bolt-N-Go Pump Packages are a great choice for replacing that worn out pump. Why put $300-$1,000 of parts & labor into fixing a pump when you can remove your old pump and Bolt-on a brand new one? All you need is a gas engine and a straight shaft (where your pump connects to the engine).

Don't compare pumps just on price! We have listed the list prices on the repair parts to completely rebuild your pump (this includes pistons/plungers, check valves and water seals) should it stop working, leak water or lose pressure. Keep in mind the average bolt-on unloader costs between $80-120. The pumps that have unloaders built into their manifold (pump head) require replacement parts that typically run $60-80
