Northstar Hot Water Pressure Washer (model #157322) While using the pressure washer the safety relief valve activated venting steam and hot water from it...

It will build a small amount of pressure, spray for a few seconds, then the pressure dropps to almost nothing. Any help ap

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 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...
