Repair of a lower pumping unit of a power washer.? Answered

A couple years ago we purchased a 31/2 hp power washer for those really tough grimy jobs around the house.  Last winter we left it outside by mistake and I suppose there was enough water in the lower unit to freeze and bust.  Anyway now it won't work, it just spews water everywhere coming from the lower unit.  I called the company and asked to purchase the lower pressure unit to replace myself, but they would not sell it to me. In fact the lady told me that the lower unit could not be purchased, but that I would have to buy all the necessary parts to disassemble it and replace the parts. When I told her it looks as if the pressure unit bolts onto the bottom of the motor with 3 bolts and perhaps was keyed onto the shaft with a keyway, she then changed her story and gave me the name of a hardware store in a small town about 20 miles away who could repair it. I took it there and the owner told me that "Sure you could buy just the lower pressure unit and he could fix it for $175.00"  I realize it was my mistake leaving it outside under my deck in the cold weather, but gee I only paid $198.00 for it brand new and the Briggs & Stratton engine still works fine. Can anyone help me?  Thanks--Debra Kay


Cheap pressure washers are exactly that. CHEAP. When you buy the one on special sale at home depot or whatever. They naturally don't have a long running life and if they break it's usually just better to get a new unit, with a new warranty. They do make better quality pumps, and they are usually connected to Honda GX engines. But they will probably start around 800 US and go way up from there. PSI also isn't always the greatest thing. You should also look at the gallons per minute that it uses (GPM) IE a squirt bottle that a hair dresser uses to wet your hair may spray at 50 psi (i'm making this number up) and your garden hose may have 10 psi. now which one would you want in a water fight? alright sorry enough of my babbling.

Buy a new unit and keep the old engine as a spare and take the old broken pump to the metal recyclers. cheers

As with cars, buying parts and labor piecemeal is a lot more expensive than buying the mass-manufactured unit off the shelf.

Suggestion: Ask him how much he'd give you for it as it stands. If he offers you more than $25, take the money and buy a replacement, possibly used; you'll come out ahead of what he's offering now.

The other solution would be to find someone who'd be willing to order the parts for you -- or to set up a business of your own, at least to the extent of printing letterhead, and ordering the parts wholesale. (Don't forget that if you do that, it's your responsibility to pay sales tax when you "sell" the parts back to yourself.) I know several folks who have done this to order from companies that normally don't sell retail. Of course, if you botch the installation you'll have only yourself to blame... again...
