Pressure Washer Leaking Pump Head Repair 

Have now used this to clean house siding and it performed well ru-vid.comUgkx43QMbQqu67IZadu9ou8Sg1BdrunMRNqX I also bought some wand extensions which enabled higher washing without needing a ladder. I recommend both. This unit arrived quickly, was easy to assemble (only had to attach the handle), and arrived in perfect condition. The only very slight downgrade from a perfect score is the design has a low handle and requires pulling from the side. My old washer was an upright model, while this one is more horizontal. Other than that, it's perfect for my needs. It has a great deal of pressure and more easily cleaned the house siding, porch rails and concrete than did my older model. The engine is a bit louder, as well, but the total time to clean was reduced by the more powerful spray. Did I mention it starts on the first or second pull every time?!! I am definitely happy with this model.

melted = run dry, or run with trigger NOT depressed. Do not run engine unless moving water. That is why electric which sghut-off when trigger not pulled last longer (but crapier quality). Thanks for video. Comments from all people also priceless.

Going to be replacing my pump here very soon,great info and nice job on the repair.

Doing the same job. Oh, you can find a completely new pump from AR (made in Italy), but at $320.00 plus shipping.... most will purchase a new P/W. I found all my parts to do a major overhaul on pump head (because top half was not leaking oil) online and now waiting for all the kits to arrive. I'm doing this repair for a friend and it's a Craftsman P/W. Note: Get an RV male water hose to air compressor adapter and with low air pressure make sure to blow all the water out of the pump for winter storage; less than 10 PSI. Great video Dave.

Noticed you bled the line, turned water valve off then started the machine and opened the valve again, your problem will happen again, never start it dry even for a moment and never let it run for an extended period of time without using the power washer.

the easy way to get the valves out is to use needle nose pliers to pull the plastic, then use an easy out for the other piece.

You should also keep trigger pulled while starting and cutting off always hold trigger on wand.

Most of the time it’s the head that needs replaced, because it frozen and cracked Keep all of the old ones for parts Seals leak

They all over Amazon

one thing you didn't mention is the pump housing can corrode - check it very carefully. pitting on it can cause water leaks

The shiny pistons need to have the rubber removed from them or over time it may destroy your new seals

I’m confused, you did a video 3 years ago where you replaced the pump, is the the new pump that went bad?

Looks like the pressure was not released and over heated it

Washer or o ring s

I have the same issue. Do you have the parts numbers by chance?

I recently acquired a pressure washer with the pump head off, and the bolts missing. Do you know what size bolts?

Sold everywhere. Its an AR (Annovi Reverberi) parts sold everywhere All Parts Equipment to name one. You make it seem harder than it is. Simple fix.

Where u find the pump head at

How much oil should I pour into the pump?

Any particular position for the plastic washers?

Bad relief valve

Do you have hard water?

What are the part numbers and what did you search on amazon tks

I hate videos where they repeat the same thing over and over again.
