I started to clean up the RV again this week. First I had to repair the pressure sprayer--when I got it out of storage it had a nice hole in the hose that could not be patched, so I bought a new hose from HD but the 22 mm connector did not fit the gun on my Harbor Freight sprayer. So I returned that and got a hose with a new gun from Amazon. But the wand from the HF sprayer didn't fit in the new gun either, not in any of the 4 adaptors that it came with. Fortuntely HD had a wand and a nozzle on clearance! Lucky me. Normally the price is $29 and the nozzle another $29 or $35 depending on the style. Those prices would have make it more economical to buy a new sprayer. As it was I spent $40 and three days of mismatched parts to fix the old one. A new one would be $89 at Amazon. Well, kept it out of the landfill before its time anyway.:S
