I have plenty of opinions now to make a decision now but I’ll keep the post up for anyone who just wants to chime in. Thanks to all who validated my concern!

Hey all so I think looking at the picture you can kinda tell I’m going to ask if these are good welds. I’m not a welder but I see issues in my eyes.

For reference, I’m a water treatment ( junior ) operator and we have a centrifuge system with a screw conveyance system. The people who rebuilt our centrifuges did not use our old cradles they it sits in, therefore the new cradles feet had to be relocated. The company who’s rebuilding our is rebuilding our conveyor system sent their welder out to relocate the feet further out. Well this is the result, I don’t want to be an ass and diss someone’s work, especially a welders but this is not something to play around with, a centrifuge is no joke when it comes to hard vibration, high speed rotation, plus the unit is about 5/6k pounds. To me I see pin holes, and it looks like the guy pretty much just cut and weld, didn’t even grind the paint down before trying to weld. Is this something that I need to show my site supervisor and project manager? Could these weld quite literally be dangerous over time on a heavily abused system?

Oh and an edit because they didn’t even close the gap on the back side of the leg… they just left a wide open hole. I’m not really liking what I see the more I look.

I guess this could fall under any tag? Any how, good morning to those un the usa.. so the past week ive been tasked with watching a trend/ pumping well- Vaults out. In this current moment what i do know is we DO NOT (NOT) have artesian wells. idk the name i just know its not that type. As you all can see we have whats shown as one vault but this is the same for 4 other wells in the same area all within...id say 150-300 ft inside of a circled area.

as a junior not knowing much about wells other then how pump, motor, pipe and pitless go together at this point. I suggested that we look into an actual well driller or company 🤷🏼‍♂️ My boss ( who is also my dad ) doesnt seem to want to listen because he thinks he can figure it out in his own without any tools or outside professional help...

so for my own sanity at what point or what things am I able to check for out in the field before i or we say that its beyond our field of expertise. What are some diagnostics that i can do to figure out why we have such a strong inflow of water into our vault.

edit: a few hours later after posting this ( automod had it removed) i had pumped down the vault and it seems our carrier pipe is leaking back into our vault.

edit 2: pretty sure we solved the why. So the sample port off the main pipe had blown off, water from our well was spraying out, eventually the vault got full untill the water was discover. we had the pump from the well off ( so we never saw the sample port hose disconnected. After draining the sump we had seen the carrier pipe leaking back because ( me being dumb not thinking) the water went into that weep hole and filled the line, which then went to another well, which filled up high enough it filled the carrier pipe through the weep hole again. We had 6 well vaults under water. I can see how gravity works now 🤣💀 there was just so much water it looked like a pipe break but its really hust because of elevation changes between the wells and that one flooded vault ended up flooding the rest of them.... fking crazy man.

So by title i am looking for advice from those who deal with instrumentation and calibration for probes.

Probe model is the title if not obvious

So in the picture you can see instructions, i read the user manual but it doesnt clearly specify and so that is why im here.

I want to make sure i handle the new probe correctly, its my first time doing this. In the oicture my brain reads this as “ Is this saying to remove the cap, shake it 3 times i a 90 degree position ( assuming due to air bubble reasons ) and then soak it in a 7 buffer prior to wiring the probe to the SC controller? “

Or “ do i wire it to the SC200 and then bring a 7 buffer outside to the coag tank let the 7 buffer sit for 45 minutes, then move to the 2 point cal using 4 & 7 buffers, wait for it to accept calibration and finally put it in the physical process? “

I assume my first question is what i should do UNLESS the probe solution they shipped with is already soaked in a 7 buffer. Which i don’t think so?

Appreciate the help as this sub has always been very good with me, please ask any question that you may need answered.

Hey all, so i picked up a 4l60e off market place 500 bucks it all looked the same except for the output shaft seal. The transmissions my old one ( on the right ) is a 6CJD the one on the left is a 0CAD but the gentlemen said he had it in a bmw and a 2006 chevy tahoe. My truck is a 2006, im confused. If the code says 0 and mine say 6 but the 0cad was in an 06… i thought 2000s models could work on a 2006 ?? The torque convertor fits flawlesslessly so it all seems the same, even at the electrical plug my harness fits on it, should i worry about fitment or should all the computer programming be fine if your even able to say…

Well i was in process of learning how to use a centrifuge for the first time ever being trained by the “ expert “ and everything went well until he opened the bypass valve on the polymer pump.

I had asked him why i wasnt seeing polymer go through the static mixer ( because i know what it looks like at our polymer station for actual plant treatment) and he couldnt tell me why.

Turns out when he opened the valve that water pressure yknow being greater than polymer, flooded back into the tote and when i saw the tote, well needless to say i got out of the way. I mean im laughing my ass off, but in the moment i was quite terrified i was gonna get soaked by a polymer explosion. Tote still hasnt blown up. I guess its a good learning experiance, dont open a bypass valve 😂

Hey all, so ive been doing a rebuild on my truck, as you can see its cab off circled in white fenders facing the front. The frame went off to powder coat so could a standard flat bed tow truck operator pull the cab onto the bed fenders first? When i had the telehandler i lifted the cab by the front windshield pillars and 2 support straps to the front radiator frame support and the fenders were fine. I just didnt know if it was safe for the fenders for a tow truck to winch it on?
