Answer to above Quiz question?
Another cleaner, this one out of San Antonio, he gets it...the Injector Swap Program.
He bought my Lifetime stainless Injector blocks, got them into his fleet, then immediately turned around and sent in his bad ones for repair. They needed it too. He sent them in on Friday and he'll have them back in his hands on Monday. I made sure of this because he went to the trouble of providing me a postage paid ($6.45) return envelope. So all I had to do was make the repairs then drop them into the envelope he provided me and beeline it to the Post Office. Easy.
Like the guy from Michigan above, he saved himself money by using US MAIL FLAT RATE ENVELOPES.
Only thing he could have done better was use cardboard envelope inside, and a padded envelope outside.
Both of his bad ones were savable and the repair costs were right at the average (see the repairs below) so he will have 6 good ones for the price of 5. Plus 4 of them have a Lifetime warranty. You guys will start realizing the built-in value of these Lifetime warrantys when you see that your metering blocks just won't die. Hell no! They're made of stainless steel instead of what you were conditioned to accept - cheap brass. Like brass jets. Who even uses brass jets anymore?!?!
Here's his packaging and invoice where he originally bot into the Swap Program, and the bad injectors he sent for repair:
In almost every repair, the draw tube and knurled knob are extremely worn and need replacing.
So if I were to make an Injector Rebuild Kit, it would definitely include the Draw Tube Assembly yet none do. Shameful.
Just look how beat up the insides of his knurled knobs were...
They're supposed to look like this.
They are hardly ever worth saving so you guys waste $35 bucks on a useless rebuild kit then go buy a whole new sprayer cuz you couldn't get it to work with the Rebuild kit they sold you. It's all part of con game your suppliers have you conditioned to accept. Get pissed. Throw up your hands and go buy another brand new sprayer.
No way that check valve is going to work right cuz it's bone on bone; steel on steel that is, the stainless ball has no rubber to seat against so hot water is gonna drain down into the jug the whole time the sprayer is in use. Not good.
The other thing all these brass injectors need is stainless nozzle bushings, not brass. A good rebuild kit would include a stainless nozzle bushing.
And just look at the rusty screw clamp and lame zip-tie.
No way anybody's gonna fix this. Can you see why Oetiker clamps are so important? Oetiker earned a US Patent for being the first clamp to breathe, that is, contract and expand as temperature & pressure changed. The patent has long since expired but I will always support the inventor.
The repair went as usual, replace the draw tube assembly, replace the nozzle bushing and clean em up a little and test. Like magic, dead injectors made as good as new again...
I gave him some new foam sleeves for being supportive of the Swap Program.
I'm gonna be helping this guy for years.
