My Craftsman/Briggs pressure washer has stopped dispensing soap from its reservoir.

Filter inside reservoir clean, right soap nozzle, all indications are the suction valve. Easy to remove -- steel ball, spring, o ring. Unit lightly used, the components look good, move freely and no back leakage with full spray nozzle.

Pics below show a threaded brass plug between the suction unit and the input connection for the garden hose. If I remove that plug, tons of suction at the suction pump input nipple. No suction with the brass plug back in.

Simple rebuild kit for the suction pump or something else? I was afraid to get any deeper into things, figured I'd booger up some gaskets.


Brass plug in, no suction --





Brass plug out, max suction --





From underneath, brass plug circled, suction pump removed. And what is that spring loaded adjuster in the center?

The spring mechanism is adjustable to let it flow depending on pressure or to allow more or less, as seen in the bottom picture you would put a flat screw driver in the flat threaded shaft, then back off the nut and tighten the flat shaft for more flow, back it off for less flow, then when you have it where you want it, tighten the nut down while holding the shaft from turning.

I have come to find I like those bottles that snap on the end of the wand to dispense soap. I have two - one for the car and one for the dog run that I add clorox bleach when I use it.

I haven't seen those, I'll check them out.

I'm wondering if my wand/soap head is the problem. They have to flow differently than the spray heads, create the right pressure to pull from the soap reservoir. The dispenser works great, a good concentrate soap goes a long way...when it works.

My pressure washer has an onboard soap dispenser also but I think these do a better job of foaming up the soap.

I think you just have to figure out what size quick disconnect you have.

Thanks, Rey HRH, I'll give it a go. Very good reviews, crazy low price, ordered.

Thanks again. Ordered Sunday a.m., got it today. I'll need to tweak the amount of soap concentrate but I was ballpark close enough to see these work well.

Reading the reviews, more than a couple people broke the reservoir bottle at the neck. Easy to figure how having that on the end of the wand could be a problem for the clumsy.

I'll rate this product as tied with Walmart's Ozark Trail Yeti knockoff cups for the deal of the millenium.
