I have a honda pressure washer that has an issue. After you let go of the water pressure trigger you have to almost throttle it down all the way to get it to be able to spit water out again. I'm picking it up from the father in laws this weekend so I actually haven't played with it myself so I'll have more details tomorrow if need be. I'm just assuming this is a common thing with pressure washers and someone here has delt with this before. THX |
Just go get a new one from Wal mart Is a joke. There was a guy a while back who slipped out of Walmart with a pressure washer on the bottom shelf of his cart that he cashier didnt see. He posted here expecting to get a pat on the back but it didnt happen. The thread went on for several pages and he ended up getting teh bannation over it. |

Sounds like someone adjusted the unloader valve to a higher pressure than the unit is rated for. It is impossible to properly adjust it with out a pressure gauge and a new nozzel. That's just a guess. It could be that the unloader has just failed and it wasn't operator error.  |

Most pressure washers have a relief valve (ETA: unloader) to bypass the water when you let go of the trigger. It sounds like the relief valve is sticking in the bypass position. Throttling down may reduce the pump output enough to un-stick the valve. The valve usually has an external spring and you may be able to see the valve shaft. A tap in the right place with a hammer will sometimes work. Or you may need to disassemble the valve and polish some parts. Or replace the valve. The relief valve is a highly stressed component on any pressure washer. The valve cycles every time the engine is started and every time the trigger is operated. Good luck! |
THX for the help. The relief valve on the honda is PLASTIC and it seems to be seized into the threads. WHen I put a socket onto it and torque it, feels like it wants to snap in half. I think you pinned my issue down for me. Now I just need to find a new valve and find a way to get the current valve off. |
Post a pic of this valve. An unloader valve isn't plastic, in fact no components on the hi side are plastic. It is entirely possible that it is a stuck unloader valve and tapping on it might unstick it for now but if you want it fixed, it probably does to be replaced. BUT it might be something else, like and easy start valve. There are in fact many different styles of unloaders than work in completely different ways. most cheaper units use a pressure actuated unloader and these trap pressure in the hose between the valve and the trigger gun. Is your doing this? There are so many questions that need to be answered be fore you just start changing parts. |
It's always funny when someone thinks we all are crooks and gets the BOOT! |
