I’d consider buying equipment from real vendors. Amazon has its place but not for most of your biz purchases.
Start here at this site’s store or try Pressure Tek. You can have confidence in what both will sell you.
@marinegrunt I look around but all of the consumer and light industrial pumps I saw are all shaft driven. Is that what you mean?
@qons Thanks man. I was just using amazon as a place for general prices and pretty pictures. Haha. I plan on sourcing most of my equipment locally if I can help it. Cuts down on shipment costs or having to pick up an entire machine at a freight station.
Even better—Find a local guy you can build a biz relationship with.
That’s a really good idea. Thanks man!

@Justus here is an excellent equipment list detailing most of what is required to get into professional residential cleaning.
It was created by @TexasPressureWashing
Begginer Equipment List - Google Sheets
Here’s my Envirospec pump and GX390 unit
Built mine for about $1600 and it’s a house washing beast. I give credit to @Patriotspwashing for turning me onto the Envirospec deal last year.
And you should be able to locate anything PressureTek carries through an alternate vendor.

@Infinity thanks for the recommendation on the hour meter/tachometer from Amazon from an old post. Works great and super easy install

I have an Allison pump and haven’t had a lick of trouble with it. For the price you just can’t beat them. I think I paid like $550 for a gear drive 7 gpm. My only reason for getting one at first is because I needed a pump asap and they could have me one in two days. I’m really glad it all worked out the way it did because I now know there’s nothing wrong with their pumps and I’d have no regrets buying another one in the future. Their customer service was top notch too.

Yeah the Allison gear drive has been great so far. Although I ordered the TSG 5638 they shipped the 6835 but I don’t care b/c I wanted the flow. Even with the GX390 it still pumps 6gpm and puts out about 2300psi at the surface cleaner, plenty to clean residential concrete with the 16” Whisper Wash. Of course I pre/post treat. Paid $508 shipped and gear drive and pump were both pre-filled with oil. On solo jobs I’ve been using it more than the GX690 7/4000 unit probably because i love the ZK1 unloader

I just ordered a zk1 unloader. Did the treads seem like they weren’t npt? The 3/8" “in” is npt but the bypass and “out” are 1/2" and don’t seem like they’re npt. I have some fittings to adapt down to 3/8" but they only want to screw on a thread or two. According to another thread the K7 has British threads or something. I wonder if the zk1 is the same way? I know @Racer uses one too so maybe he’ll know.
My K1 has 3/8” in and out. Bypass is 1/2”. I got a 3/8” unloader block from Bob and the K1 came from PWP. I rigged up some fittings from ACE to convert the bypass from 1/2” male to hose barb. Bypass line is 5/8” heater hose
Sure seemed like NPT to me.

All the descriptions say mpt so they must be. Maybe the coupling I was trying to screw on is different threads. It won’t even screw on more than 3/4 of a turn.
I didn’t even see the zk1 with the 3/8" out when I ordered. I went through Kleen-Rite just because they were $20 cheaper. I should’ve looked a little better and I wouldn’t need to add a bushing. I guess I could drill out and tap the unloader block to 1/2".

TBH I’ve seen most sites describe (2) 1/2” ports and (1) 3/8”. Don’t remember which was in/out/bypass so I had it in my mind to order a 1/2” unloader block and be prepared to do some coupling work. But the one from PWP is listed as a K1, not ZK1 and it only has the 1/2” bypass. Here is the description from GP website. Notice the threads are BSP-M/F. Maybe the “Z” designation is Europe?
I believe @Jake_Lambert said he has one with BSP threads. If Kleen Rite sold you a product with BSP they need to be kicked in the nads. That’s ridiculous for a US based vendor to send a US based customer a non US standard unloader. That’s all we use is NPT. Yes i know there’s 22mm or whatever fittings. I’d demand a refund.
Mine is labeled as K1 only too so pretty sure they’re the same except for the outlet size. At least it has a sticker on it that says “K1 Made in Italy”. I don’t see K1 stamped on it though. PWP sells both the 3/8" and 1/2" outlet. I think Jake was talking about the K7. He said something to the effect that the reason they don’t switch over to NPT from BSP is it adds too much cost to the product. He was told by some vendor that you’re fine using npt with the bsp. It won’t twist on as far but shouldn’t leak. You’re only talking about a couple threads though. I don’t like the idea of that too much.

All of it is BSP from unloaders to pump manifolds. You just thought it was NPT this whole time. For simplicity sake they ARE they same. Look it up, the difference in them is negligible. You’ll find the same with AN and JIC fittings
If it’s manufactured in Italy it is in fact BSP but we’re talking brass here so it will deform just run it

Thanks for the clarification on Jake’s post.

That’s interesting. The outlet on this one just seems different. Every other pressure washer fitting I could at least turn the other fitting a few rotations. This one doesn’t even make it one turn. Actually, I just checked and it only turns 1/4 turn by hand.

You’ll see the same thing with NPT, like they didn’t go very deep with the tap
