I'm having technical difficulties with my pressure washer. I'm hoping someone can confirm for me that it's the unloader.

I started losing pressure while washing, and the engine kept making a weird revving noise that would ramp up and then suddenly drop. For a while, the pressure would return after a few seconds, so I continued working, but eventually it seemed permanently lost.

At first I assumed it was a water supply issue, but that was ruled out. There's no blockage in my wand or hose. The engine seems fine so I'm pretty sure it's something to do with the pump. AI suggested it's either the check valves or the unloader.

I took off the unloader to take a look. See video in first comment for a quick demo (forgot to include, duh). I don't know how to get right inside it, from how it's operating in my hand, I think the spring must be broken.

Can anyone confirm or deny this? Or tell me now to get inside this thing to check the spring? Thanks y'all.

My client has 2 wood fences he wants cleaned. One is old and looks like bare wood. It's dirty and dingy and basically needs to be restored, after which he plans to stain it. I was planning on using metasilicate first, then pressure wash at low pressure, and then follow that with oxalic acid. Is this an appropriate workflow? Maybe overkill?

The other fence is much newer and has been stained with something semi-transparent. The coating appears to be in good shape. He basically just wants the dirt and algae cleaned off. How can I clean it without stripping or otherwise damaging the finish? Will metasilicate work for this or is that only for bare wood? Should I just use water pressure without chemicals?

Thanks for any guidance. I'm a noob chemical-wise. I only use percarb currently and usually only for killing roof moss.

I've done a little experimentation with the few blowers available to me. Both CFM and MPH seem important. From a purely performance perspective, maximizing both would be best. But the higher cost, weight, and noise of more powerful blowers must set a limit on what is practical or desirable. Where's your sweet spot? If you have any specific blowers to recommend, I'd love to hear it.

Just in case you're not familiar, leaded windows (aka came windows) are windows made up of many small panes of glass held together by lead channels called cames. Decorative stained glass windows are came windows. More commonly, at least on houses, they are simple grids similar to how french panes are arranged, although they are sometimes on the diagonal.

So, to those of you who know what I'm talking about, how do you clean them? Do you take any special safety precautions (because of the lead)?

I encounter these fairly often on older houses. I've always treated them the same as frenchies, washing and detailing each individually, but I'm wondering if there's a better way. WFP is not an option. At best, you'd get water leaking through. At worst, you'd just break them.
