I was given a low hour, 10 year old, CH PW205002LE 6.5 HP gas vertical shaft 2000 PSI/2.5 GPM pressure washer with a Lavor pump. It did not work - no pressure. I found a broken o-ring on the brass unloader valve and replaced it with a ring as close in size as I could find as the part break down doesn't state size. Everything was very clean. I coated everything with silicine grease and reassembled, seating the brass piston? as deep as it would go. I had to press the trigger in order to get the mo

I recently replaced the water seals, V-packing & all six check valves in a CW-3504-4MGH pump on a MiTM 3504 pressure washer that had very low pressure. Usually this would fix most pressure problems on most machines, but in this case it had little to no effect. I suspect that the unloaded is the culprit in this case, but since I have had little experience in repairing unloaders (let alone adjusting them). I would appreciate feedback from anyone that has experience in this area. Thanks

I have changed the unloader valve, checked all the valves and seals ad they seem to be fine. What could be the problem?

I have a HD 2701 DR pressure washer that starts and runs fine and usually works fine the "first" time but if you let go of the trigger and then try to use it again you just get a trickle out of the end of the wand. Usually if you hold the thing open for a while it will kick in (sometimes it takes forever...). Any ideas? It sounds like some of the "unloader valve" problems are similar but I do not see an "unloader valve" in the parts lists for the 2701...
