I was under the impression that all PWing pumps were made in one factory in Italy?
No, some guys here think that, but that’s like thinking one place in Detroit makes all brands of cars. My Landa guy has visited a couple of the Italian plants.

So there’s multiple factories but they’re all in Italy?
There are a lot of factories close to each other in Italy, but not all of them are made there. Suttner makes a ton of the industries unloaders, there are just branded for different companies. Cat sources several places for unloaders, but they don’t have facilities to make their own. General makes some of their own, but they aren’t really on par with Suttner.

Wait a minute I saw you promoting your Landa dealer earlier this year. What machines do you use?
Your Landa guy? Not prodding just trying to figure out what you use. You are the guru after all
My Landa guy builds how own machines in house, as well as selling Landa equipment. I run his custom equipment.

As nobody can present any reasoning nor evidence for why one shouldn’t adjust the pressure with the purpose-built unloader, we can safely assume it’s a pressure washing form of bro science. “Trust me bro”. Nah.
Let me educate you grasshopper. Safety is the number 1 reason because of pressure spikes and stress on equipment. An unloader valve set to maximum spring tension could require up to twice the pressure to go into bypass mode depending on spring rate. Most quality things in this industry are designed to what’s called a society of automobile engineers’ standard for hydraulic components, what that standard is, is a 4 times burst pressure of standard designed operating pressure for safety. The fun begins when you buy a crappy no name fitting or gun with no such stringent testing example being a 2000psi rated gun or hose, what happens when you spike to 3-4 thousand psi on mass produced garbage? well you guessed right it could blow up in your hand or hose could blow up in your face. That’s why you set the unloader to the psi you want and use tips to govern pressure the unloader will take care of the rest. There’s a reason for everything my friend you just have to be teachable.

Good stuff @MuscleMyHustle ! I was just reading about it actually. @jcfin do some research AR article discusses it. I respect a lot of these guys and trust a lot of what they say but I’m also old enough to “trust but verify” which means taking what they say and digging into it so I actually understand what’s being said.
Also from General Pump on unloaders: “Once an unloader is set it should never have to be adjusted again unless there are modifications done to the system.” Article
@Innocentbystander I noticed on the blue pickup that you have a 6"-8" air gap above your buffer tank. Is that a requirement to fill from hydrants? Are you still required to have a backflow restrictor when you have an air gap? Just curious. Love the service bodies, very efficient setup.
Different cities require different things. Some require me to provide my own meter and back flow preventer, some provide their own meter and require an air gap. It’s just easier to run an air gap on all the trucks, even if hooked up to a garden hose at someone’s house
Thank you.
My youth is showing here, but what is an air gap used for?

It prevents backflow. Otherwise, chemicals/nasty water could conceivably go back into the municipal supply and taint it
